    In the authors business of providing district energy services, competition is the key to his being able to have a positive impact on the environment, business stability, and economic activity. In the district energy industry, the competitive options are for property owners to continue to self generate energy to meet their needs, purchase energy from a company that utilizes electricity during off-peak hours to produce chilled water or take advantage of a total solution of purchasing tri-generation energy from Trigen-Peoples District Energy Company. Tri-generation is an innovative technology which involves the simultaneous production of steam, chilled water, and electricity. The McCormick Place cogeneration project calls for producing steam and chilled water (co-) for use by the Metropolitan Pier and Exposition Authority (MPEA). The plant will produce electricity (tri-) to run the production equipment.

    To meet BPA`s contractual obligation to supply electrical power to its customers, BPA proposes to acquire power generated by Klickitat Cogeneration Project. BPA has prepared an environmental assessment evaluating the proposed project. Based on the EA analysis, BPA`s proposed action is not a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act of 1969 for the following reasons: (1)it will not have a significant impact land use, upland vegetation, wetlands, water quality, geology, soils, public health and safety, visual quality, historical and cultural resources, recreation and socioeconomics, and (2) impacts to fisheries, wildlife resources, air quality, and noise will be temporary, minor, or sufficiently offset by mitigation. Therefore, the preparation of an environmental impact statement is not required and BPA is issuing this FONSI (Finding of No Significant Impact).

    The Waste-to-Energy Cogeneration Project at Centennial Park has allowed methane from the closed Centennial landfill to export excess power into the the local utility’s electric grid for resale. This project is part of a greater brownfield reclamation project to the benefit of the residents of Munster and the general public. Installation of a gas-to-electric generator and waste-heat conversion unit take methane byproduct and convert it into electricity at the rate of about 103,500 Mwh/year for resale to the local utility. The sale of the electricity will be used to reduce operating budgets by covering the expenses for streetlights and utility bills. The benefits of such a project are not simply financial. Munster’s Waste-to Energy Cogeneration Project at Centennial Park will reduce the community’s carbon footprint in an amount equivalent to removing 1,100 cars from our roads, conserving enough electricity to power 720 homes, planting 1,200 acres of trees, or recycling 2,000 tons of waste instead of sending it to a landfill.

    This report describes a two-phase energy project currently contemplated for joint implementation at the Victorias Milling Company, a large sugar mill and refinery on the island of Negros in the Visayas region of the Philippines. The Energy Efficiency (EE) phase is expected to reduce of eliminate VMC`s fossil fuel consumption, which will have a direct and substantial impact on carbon emissions. Phase I is an EE project which involves the installation of equipment to reduce steam and electricity demand in the factories. Phase II, will involve retrofitting and increasing the capacity of the steam and power generation systems, and selling power to the grid. By increasing efficiency and output, the cogeneration project will allow the factory to use only bagasse sugar cane fiber waste as fuel for energy needs. The cogeneration project will also eliminate VMC`s electricity purchases and supply additional power for the island, which will offset generation capacity expansion on the island and the Visayas region.

    Wheeling electric power, the transmission of electricity not owned by an electric utility over its transmission lines, is a term not generally recognized outside the electric utility industry. Investigation of the term`s origin is intriguing. For centuries, wheel has been used to describe an entire machine, not just individual wheels within a machine. Thus we have waterwheel, spinning wheel, potter`s wheel and, for an automobile, wheels. Wheel as a verb connotes transmission or modification of forces and motion in machinery. With the advent of an understanding of electricity, use of the word wheel was extended to be transmission of electric power as well as mechanical power. Today, use of the term wheeling electric power is restricted to utility transmission of power that it doesn`t own. Cogeneration refers to simultaneous production of electric and thermal power from an energy source. This is more efficient than separate production of electricity and thermal power and, in many instances, less expensive.

    The Department of Energy, under the Clean Coal Technology program, proposes to provide cost-shared financial assistance for the construction of a utility-scale circulating fluidized bed technology cogeneration facility by York County Energy Partners, L.P (YCEP). YCEP, a project company of ir Products and Chemicals, Inc., would design, construct and operate a 250 megawatt (gross) coal-fired cogeneration facility on a 38-acre parcel in North Codorus Township, York County, Pennsylvania. The facility would be located adjacent to the P. H. Glatfelter Company paper mill, the proposed steam host. Electricity would be delivered to Metropolitan Edison Company. The facility would demonstrate new technology designed to greatly increase energy efficiency and reduce air pollutant emissions over current generally available commercial technology which utilizes coal fuel. The facility would include a single train circulating fluidized bed boiler, a pollution control train consisting of limestone injection for reducing emissions of sulfur dioxide by greater than 92 percent, selective non-catalytic reduction for reducing emissions of nitrogen oxides, and a fabric filter (baghouse) for reducing emissions of particulates. Section II of this report provides a general description of the facility. Section III describes the site specifics associated with the facility when it was proposed to be located in West Manchester Township. After the Cooperative Agreement was signed, YCEP decided to move the proposed site to North Codorus Township. The reasons for the move and the site specifics of that site are detailed in Section IV. This section of the report also provides detailed descriptions of several key pieces of equipment. The circulating fluidized bed boiler (CFB), its design scale-up and testing is given particular emphasis.

    Cogeneration is very important to spread the use of natural gas in Brazil. Most of the existing cogeneration plants are of considerable size, as used in industries or commercial centers. Places with low demand on electrical or thermal energy (e.g. small industries, blocs of houses, etc.) could also benefit of cogeneration, but there is no available data about micro-cogeneration in Brazil. In order to verify the technical and economical viability of small size systems of cogeneration, FINEP/PETROBRAS/COPERGAS financed a project of micro-cogeneration at the Federal University of Pernambuco (UFPE), involving experiments on a micro turbine and a generator group, both with 30 kW power. The laboratory is also composed by two heat exchangers to regenerate the heat from the micro-turbine and generator group, a single effect absorption chiller, with 10 TR capacity, two thermal storage tanks (for hot and cold water) and a compression split of 5 TR. Data to build performance curves of the equipment will be stored and analyzed, in order to build their performance curves, allowing the overall cogeneration efficiency to be found. Most probable situations of thermal and electric power demands will be simulated. The aim of the simulations is to achieve the optimal situation for micro-cogeneration, which will offer the best efficiency, the lowest cost for buying the equipment and the lowest operational cost. A software was also developed, which optimizes micro-cogeneration systems. (author)

    As part of the promotion of new energy technologies the Flemish government has attached a subsidy of 35 per cent for the investment costs of a cogeneration installation in combination with an absorption refrigerating machine to the company Anala that is specialized in anodizing aluminiumprofiles for third persons. The Flemish Institute for Technological Research is doing an evaluation of this demonstration project by order of the Department Natural Resources and Energy. The energy flows were measured and registered and based on these measurements the technical performances, the achieved energy savings, the diminution of the CO2-emission and the profitability were evaluated. During the measurement period the cogeneration installation has been working for 2.785 hours, at which 398.656 liter gas oil was consumed and 1.507 MWh of electricity was produced. This corresponds with an average electric capacity of 541 kW. The average electric efficiency of the cogeneration installation is about 38 per cent and the average thermal efficiency is about 35 per cent, which takes the total efficiency up to 73 per cent. The total energy relation is for the most of the months about 0.9. The electric efficiency with full load is between 40 per cent and 41per cent. The global efficiency and the total energy relation would be higher, if the heat for the oil cooling and the intercooler would be usefully used next to the heat of the engine block cooling and the flue gas cooling, which was normally provided for the production of distilled water. The primary energy consumption of the installation is 18.778 GJ/year. The primary energy use with separate generation is 23.879 GJ/year. The savings on primary energy use are 5.101 GJ/year. The CO2-emission of the cogeneration is 1.371 ton/year for the measurement period 1997. With separate production, the CO2-emission would be 1.796 ton/year. The reduction of the CO2-emission during the measurement period is 425 ton/year, or 24 per cent compared

  17. Flexibility and uncertainty in agribusiness projects: investing in a cogeneration plant.

    Full Text Available Energy generation from biomass has become a source of increasing interest due to growing environmental concerns and the depletion of the world’s fossil fuel reserves. In this paper we analyze a sugar and ethanol producing plant in Brazil which has both the option to expand and to add a cogeneration unit to allow the sale of surplus energy, generated by burning sugar cane bagasse, where the existence of the second option is conditional to the exercise of the first option. We model sugar, ethanol, and electricity prices as geometric mean reverting processes and apply the real options approach to determine the value of these managerial flexibilities, considering that these options have three distinct underlying assets. The option to expand production is a function of the expected future prices of sugar and ethanol, while, on the other hand, the decision to invest in the cogeneration plant will depend on the future prices of energy. Both decisions are modeled as American Compound Options over their respective underlying assets. The model is then solved using the non-censored binomial mean reverting lattice proposed by Bastian-Pinto, Brandão, and Hahn (2010 using the software DPLTM. The results indicate that a significant value can be derived from the flexibility to choose the optimal timing of investment in both options: the investment in the cogeneration unit adds an amount equivalent to the value of the expanding sugar and ethanol production, and represents up to 44% of the project’s static NPV of R$ 195.9 million. We conclude that given that only half of the sugar cane crushing mills currently have cogeneration units installed and given the increasing demand for clean and renewable sources of energy, this may indicate there is a significant potential for investment and further development of bioelectricity cogeneration power plants, and even in the retrofit of older cogeneration units, and that government incentives have been effective in

    In 1982 Shell and Heineken entered into a basic agreement on investing and exploiting a cogeneration installation for the Heineken production department in Zoeterwoude, Netherlands. For this purpose the Energy Conversion Company Zoeterwoude (ECMZ) was founded. The ECMZ purpose is to converse gas and water into electric power and steam. Before realizing the construction of a cogeneration plant a feasibility study was done, of which the results are given. Details of the cogeneration installation are explained with the help of illustrations. The installation is in operation for more than two years and in technical respect not disappointing. Financial-economical the project did not come up to expectations as a consequence of decrease in energy prices in 1985.

    Thanks to a new inciting tariff of electricity purchase, the cogeneration market is making rapid strides, especially in the 1 to 4.5 MWe power range. The energy efficiency subsidy will lead to more efficient and profitable installations with a better heat recovery quality. The needs of high quality and high reliability current for the E-business will offer new opportunities. Moreover, the existence of a low voltage tariff will favor the development of micro- and rural-cogeneration or cogeneration from biomass fuels. The aim of this seminar is to debate about the place of cogeneration in the French energy policy: 1 - which opportunities for the new cogeneration (new trends of the European Commission in the development of decentralized power production, which perspectives for the French cogeneration); 2 - optimization of cogeneration profitability (new regulatory conditions of electricity purchase, problem of the connection of decentralized power production facilities to the grid, how to cover the gas price risk); 3 - the adaptation of the technique to the offer (situation of combustion turbines in the framework of new contracts, the truth about micro-turbines, the cogeneration engines in the new tariff environment, technologies for biomass-fueled cogeneration units); 4 - the new markets of the decentralized production (the high quality and high availability power supplies market, the cogeneration in district heating networks, the tri-generation, the rural advantages of small cogeneration units (<1 MW)).

    This final report for the Swiss Federal Office of Energy (SFOE) proposes an alternative for micro-cogeneration based on a scroll expander to produce electricity from relatively low-temperature heat sources (less than 250 {sup o}C), thus allowing the use of renewable energy resources such as biomass, solar thermal and geothermal energy. The authors note that such a system could produce cost-effective 'green' electricity as well as heat (near 60 {sup o}C) for space heating and domestic hot-water preparation. The design and validation of a new concept for a double-stage scroll expander ('HT-Scroll') operating at high and low pressures and high temperatures is discussed. Design, modelling and construction of a 5 kW unit have been carried out. The organic fluid Rankine Cycle concept is described, the modelling of the turbine, its construction and tests carried out are discussed. Problems encountered and future work are noted.

    China`s energy production is largely dependent on coal. China currently ranks third in global CO{sub 2} emissions, and rapid economic expansion is expected to raise emission levels even further in the coming decades. Cogeneration provides a cost-effective way of both utilizing limited energy resources and minimizing the environmental impacts from use of fossil fuels. However, in the last 10 years state investments for cogeneration projects in China have dropped by a factor of 4. This has prompted this study. Along with this in-depth analysis of China`s cogeneration policies and investment allocation is the speculation that advanced US technology and capital can assist in the continued growth of the cogeneration industry. This study provides the most current information available on cogeneration development and market potential in China.

    The consumption of electricity, natural gas, or fuel oil was surveyed. The potential electricity that could be generated in the SCE service territory using cogeneration technology was estimated. It was found that an estimated 3700 MWe could potentially be generated in Southern California using cogenerated technology. It is suggested that current technology could provide 2600 MWe and advanced technology could provide 1100 MWe. Approximately 1600 MWt is considered not feasible to produce electricity with either current or advanced cogeneration technology.

    1982-07-01

    This report summarizes two interdependent studies which explore the underlying factors in the decision by private, private non-profit, and public sector facility owners to invest in cogeneration technology. They employ factor analysis techniques to explain the decision to invest and discriminant analysis to group the survey respondents into non-cogenerators and potential cogenerators. Data for both studies come from a survey of commercial, industrial, and institutional electric energy consumers who used more than 750 kW demand in any one month of 1981 for a selected electric utility in the Boston area. There were 129 usable responses to the survey of 32.2% of the population. The studies reported here confirm that a number of factors other than purely economic considerations may prevent use of cogeneration technology at the present time. These factors include: uncertainty caused by regulatory action; desire for energy self sufficiency by the organization; financial flexibility; experience with electricity cogeneration or self generation; and capital budget planning methods. These studies provide a ranking of the factors involved in the cogeneration decision explaining most variance to least variance. However, the ranking of factors provides no measure of the importance of these factors in the decision to adopt or not adopt cogeneration technology. The results of these studies can be used to provide a rough estimate of capacity (kW) and energy (kWh) available from potential cogenerators in this electric utility service territory and the probability that a facility can be a cogenerator. These studies project a maximum potential of 106 MW and 559,000 MWH of cogenerated electrical energy in the utility service territory between 1982 and 2002.

    BPA is considering whether to transfer (wheel) electrical power from a proposed privately-owned, combustion-turbine electrical generation plant in Oregon. The plant would be fired by natural gas and would use combined-cycle technology to generate up to 440 average megawatts (aMW) of energy. The plant would be developed, owned, and operated by Portland General Electric Company (PGE). The project would be built in eastern Oregon, just east of the City of Boardman in Morrow County. The proposed plant would be built on a site within the Port of Morrow Industrial Park. The proposed use for the site is consistent with the County land use plan. Building the transmission line needed to interconnect the power plant to BPA`s transmission system would require a variance from Morrow County. BPA would transfer power from the plant to its McNary-Slatt 500-kV transmission line. PGE would pay BPA for wheeling services. Key environmental concerns identified in the scoping process and evaluated in the draft Environmental Impact Statement (DEIS) include these potential impacts: (1) air quality impacts, such as emissions and their contributions to the {open_quotes}greenhouse{close_quotes} effect; (2) health and safety impacts, such as effects of electric and magnetic fields, (3) noise impacts, (4) farmland impacts, (5) water vapor impacts to transportation, (6) economic development and employment impacts, (7) visual impacts, (8) consistency with local comprehensive plans, and (9) water quality and supply impacts, such as the amount of wastewater discharged, and the source and amount of water required to operate the plant. These and other issues are discussed in the DEIS. The proposed project includes features designed to reduce environmental impacts. Based on studies completed for the DEIS, adverse environmental impacts associated with the proposed project were identified, and no evidence emerged to suggest that the proposed action is controversial.

    Dispatchable renewable power generation is usually associated with expensive storages or additional back-up systems. Solar-hybrid systems can combine solar energy with an additional fuel and thus reliably provide electric power. If renewable fuels (e.g., biofuels) are employed, power generation becomes 100% sustainable at zero net emissions. Systems based on gas turbines are suited for cogeneration or combined cycles, making them very efficient and cost effective. These cycles require high temperatures and pressures, thus the solar energy has to be concentrated by a heliostat field onto the top of a tower and transferred by a solar receiver into the gas turbine cycle. At smaller power levels, cogeneration of heat and power is an attractive option by making use of the high exhaust temperature of the gas turbine, thus getting an additional benefit. The aim of this proposal is an significant extension of the objectives of the recently started SOLHYCO project by means A profound knowledge for market introduction will be gained by the assessment of the Brazilian market concerning solar resources, biofuels, electricity markets, heat markets and social needs. A detailed design study for a first demonstration unit will deliver all necessary economical, social and environmental data and accordingly 3 case studies have been defined. (author)

  12. Industrial cogeneration optimization program

    Energy Technology Data Exchange (ETDEWEB)

    1980-01-01

    The purpose of this program was to identify up to 10 good near-term opportunities for cogeneration in 5 major energy-consuming industries which produce food, textiles, paper, chemicals, and refined petroleum; select, characterize, and optimize cogeneration systems for these identified opportunities to achieve maximum energy savings for minimum investment using currently available components of cogenerating systems; and to identify technical, institutional, and regulatory obstacles hindering the use of industrial cogeneration systems. The analysis methods used and results obtained are described. Plants with fuel demands from 100,000 Btu/h to 3 x 10/sup 6/ Btu/h were considered. It was concluded that the major impediments to industrial cogeneration are financial, e.g., high capital investment and high charges by electric utilities during short-term cogeneration facility outages. In the plants considered an average energy savings from cogeneration of 15 to 18% compared to separate generation of process steam and electric power was calculated. On a national basis for the 5 industries considered, this extrapolates to saving 1.3 to 1.6 quads per yr or between 630,000 to 750,000 bbl/d of oil. Properly applied, federal activity can do much to realize a substantial fraction of this potential by lowering the barriers to cogeneration and by stimulating wider implementation of this technology.

    Two interdependent studies which explore the underlying factors in the decision by private, private non-profit, and public sector facility owners to invest in cogeneration technology are summarized. The employ factor analysis techniques to explain the decision to invest and discriminant analysis to group the survey respondents into non-cogenerators and potential cogenerators. Data for both studies come from a survey of commercial, industrial, and institutional electric energy consumers who used more than 750 kW demand in any one month of 1981 for a selected electric utility in the Boston area. There were 129 usable responses to the survey of 32.2% of the population. The studies confirm that a number of factors other than purely economic considerations may prevent use of cogeneration technology at the present time. These factors include: uncertainty caused by regulatory action; desire for energy self sufficiency by the organization; financial flexibility; experience with electricity cogeneration or self generation; and capital budget planning methods.

    Cogeneration is quite spread in Denmark. Approx. 50 % of the power supply and 80 % of the district heating supply come from cogeneration. Combined heat and power is produced on both centralized (large) plants and decentralized plants. Decentralized combined heat and power plants (typically based on natural gas) use gas motors or gas turbines for power and heat production. Cogeneration of heat and power saves primary fuels and a directly derived effect from cogeneration is CO{sub 2} emission reduction. If fuels with higher specific CO{sub 2} emission than natural gas (e.g. coal, oil) are substituted, additional CO{sub 2} reduction can be reached. (BA)

    Achieving geoscience literacy of the general population has become increasingly important world wide as ever more connected and growing societies depend more and more on our planet's limited natural resource base. Building citizen understanding of their dependence on the local environment, and the geologic processes which created and continue to change it, has become a great challenge to educators at all levels of the education system. The Special Place Project described in this presentation explores use of a place-based case study approach combining instruction in geoscience content with development of observation, reasoning, writing and presentation skills. The approach allows students to select the locations for their individual case studies affording development of personal connections between the learner and his environment. The approach gives instructors at many grade levels the ability to develop core pedagogical content and skills while exploring the unique geologic environments relevant to the local population including such critical issues as land use, resource depletion, energy, climate change and the future of communities in a changing world. The geologic reasons for the location of communities and key events in their histories can be incorporated into the students' case studies as appropriate. The project is unique in placing all course instruction in the context of the quest to explore and gain understanding of the student's chosen location by using the inherently more generalized course content required by the curriculum. By modeling how scientists approach their research questions, this pedagogical technique not only integrates knowledge and skills from across the curriculum, it captures the excitement of scientific thinking on real world questions directly relevant to students' lives, increasing student engagement and depth of learning as demonstrated in the case study reports crafted by the students and exam results.

    Cogeneration, simply, is the generation of energy for one process from the excess energy supplied to another process. Cogeneration, then, is nothing more than an economically sound method for the conservation of resources. Thus, the benefits from the use of cogeneration may be cited as energy conservation, environmental improvement and financial attractiveness to investors. In the near future energy efficiency must no longer be a choice, but a commitment - hence the timely importance of this review. (author)

    A mathematical linear programming (LP) model was developed to optimize the decision-making for managing a cogeneration facility as a potential clean-development mechanism project in a hospital in Palestine. The model was developed to optimize the cost of energy and the cost of installation of a small cogeneration plant under constraints on electricity-and-heat supply and demand balances. In the model, the sources of electricity are either from cogeneration or public utilities and it was calculated the least cost to supply electricity and heat to the hospital. The hospital is using heat for their operation and that made the application for the cogeneration to be attractive and feasible. In this study, we will develop the LP model and will show the results and the time schedule for the cogeneration. This developed LP model can be used and run to any cogeneration application with little modification. (orig.)

    A feasibility study was carried out in 1993 by Skellefteaa Kraft AB, to analyse the technical and economical possibilities to build a new baseload district heating production plant. The conclusion from the study was that, as a first step, a new cogeneration plant, based on a circulating fluidised bed boiler, should be built. The commissioning of the cogeneration plant took place in autumn 1996. The plant was prepared for a future integration with a biofuel drying process for pellets production. During spring 1996 an investment decision was taken and the fuel factory was erected in may 1997. Vaermeforsk Service AB has financed this research project and the Swedish state energy program (Fabel) has contributed with 33,7 Million SEK to the financing of the recovery electric power generation part of the fuel factory. The aim with this research project has been to evaluate and compare the integrated cogeneration plant fuel factory concept with a conventional co-generation plant, specially when it comes to increased power generation. The fuel factory comprises of fuel feeding system, fuel dryer, steam converter from fuel moisture to low pressure process steam, low pressure condensing turbine, cooling water system, fuel pellets production and storage with ship loading plant in the harbour of Skellefteaa. The steam to the fuel factory is extracted from the cogeneration turbine at a pressure level between 12-26 bar and the extraction flow has then already generated power in the cogeneration turbine. Power is also generated in the low pressure condensing turbine of the fuel factory. The low pressure steam is generated with fuel moisture in the steam converter. During the first years of operation there has been both conventional commissioning problems but also technical problems related to the new process concept. The last are for example corrosion and erosion problems, fouling problems of heat exchangers, capacity and leakage problems. The performance goals of the fuel

    Cogeneration cycle is an efficient mean to recover the waste heat from the flue gases coming out of gas turbine. With the help of computer simulation, design parameters may be selected for the best performance of cogeneration cycle. In the present work a program is executed in software EES on the basis of mathematical modelling described in paper to study cogeneration cycle performance for different parameters. Results obtained are compared with the results available in literature and are found in good agreement with them. Real gas and water properties are inbuilt in the software. Results show that enthalpy of air entering the combustion chamber is higher than that of the flue gases at combustion chamber outlet. For different operative conditions, energy and exergy efficiencies follow similar trends; although, exergy efficiency values are always lower than the corresponding energy efficiency ones. From the results it is found that turbine outlet temperature (TIT) of 524°C is uniquely suited to efficient cogeneration cycle because it enables the transfer of heat from exhaust gas to the steam cycle to take place over a minimal temperature difference. This temperature range results in the maximum thermodynamic availability while operating with highest temperature and highest efficiency cogeneration cycle. Effect of cycle pressure ratio (CR), inlet air temperature (IAT) and water pressure at heat recovery steam generator (HRSG) inlet on the 30MW cogeneration cycle is also studied.

    1993-07-01

    District energy systems are a major part of the energy use and delivery infrastructure of the United States. With nearly 6,000 operating systems currently in place, district energy represents approximately 800 billion BTU per hour of installed thermal production capacity, and provides over 1.1 quadrillion BTU of energy annually -- about 1.3% of all energy used in the US each year. Delivered through more that 20,000 miles of pipe, this energy is used to heat and cool almost 12 billion square feet of enclosed space in buildings that serve a diverse range of office, education, health care, military, industrial and residential needs. This Census is intended to provide a better understanding of the character and extent of district heating, cooling and cogeneration in the United States. It defines a district energy system as: Any system that provides thermal energy (steam, hot water, or chilled water) for space heating, space cooling, or process uses from a central plant, and that distributes the energy to two or more buildings through a network of pipes. If electricity is produced, the system is a cogenerating facility. The Census was conducted through surveys administered to the memberships of eleven national associations and agencies that collectively represent the great majority of the nation`s district energy system operators. Responses received from these surveys account for about 11% of all district systems in the United States. Data in this report is organized and presented within six user sectors selected to illustrate the significance of district energy in institutional, community and utility settings. Projections estimate the full extent of district energy systems in each sector.

    2016-07-01

    Full Text Available Benefit analysis of emergency standby system combined with absorption chiller promoted to cogeneration system is introduced. Economic evaluations of such upgraded projects play a major part in the decisions made by investors. Time-of-use rate structure, fuel cost and system constraints are taken into account in the evaluation. Therefore, the problem is formulated as a mixed-integer programming problem. Using two-stage methodology and modified mixed-integer programming technique, a novel algorithm is developed and introduced here to solve the nonlinear optimization problem. The net present value (NPV method is used to evaluate the annual benefits and years of payback for the cogeneration system. The results indicate that upgrading standby generators to cogeneration systems is profitable and should be encouraged, especially for those utilities with insufficient spinning reserves, and moreover, for those having difficulty constructing new power plants.

    The advanced cogeneration technology economic optimization study (ACTEOS) was undertaken to extend the results of the cogeneration technology alternatives study (CTAS). Cost comparisons were made between designs involving advanced cogeneration technologies and designs involving either conventional cogeneration technologies or not involving cogeneration. For the specific equipment cost and fuel price assumptions made, it was found that: (1) coal based cogeneration systems offered appreciable cost savings over the no cogeneration case, while systems using coal derived liquids offered no costs savings; and (2) the advanced cogeneration systems provided somewhat larger cost savings than the conventional systems. Among the issues considered in the study included: (1) temporal variations in steam and electric demands; (2) requirements for reliability/standby capacity; (3) availability of discrete equipment sizes; (4) regional variations in fuel and electricity prices; (5) off design system performance; and (6) separate demand and energy charges for purchased electricity.

    The emissions of Greenhouse Gases (GHG), the resulting intensification of the greenhouse effect and its relation with climate change, have been pointed out as serious global problem. For this reason, the Kyoto Protocol was established, within the United Nations Framework Convention on Climate Change (UNFCCC), with the objective of setting up directives and goals to the stabilization and reduction of GHG emissions. In its Article 12, the Kyoto Protocol institutes the Clean Development Mechanism, an important flexibility instrument to Annex 1 Parties in achieving their emission reduction targets through project implementation in developing countries (non-Annex 1 Parties), promoting Sustainable Development and incurring and lesser costs of emission reductions. Any project, to be qualified within the Clean Development Mechanism, must fulfill the eligibility criterions fixed by the Kyoto Protocol, which are: promotion of Sustainable Development and assurance of the project additionality. In Brazil, the sugarcane industry is a promising opportunity of developing these kind of projects, specially by means of the cogeneration from sugarcane residues. This paper analyses the Additionality of this sort of projects, in the light of the criterions defined by the UNFCCC, with special attention to the two Brazilian cases registered in the CDM Methodologies Panel.

    In this paper, presents a methodology of how to calculate the emissions of CO{sub 2} (Carbon Dioxide) in cogeneration of plants for evaluate future cases with the type of fuel and fuel flow used in the plant. The methodology was in spreadsheets developed a series of stoichiometric balances. The methodology was done for three types of fossil fuels: solid, liquid and gas. The analysis is made only to the percentages of the items contained in the fuel flow automatically used and results in the combustion products in tons per hour. This method was compared with the results obtained in the software Thermoflow Inc. (Used in Gerencia de Procesos Termicos of Instituto de Investigaciones Electricas for evaluate various process systems that produce energy power) using different cogeneration systems, that is to say about the technology used emissions compared according to the amount of excess air for each type of technology and at one point before the gas cleaning systems. The results can be evaluated for emissions avoided through the fuel type used and developing a cogeneration plant compared to a conventional plant.

A male rugby player performed 49 maximum-effort kicks using projection angles of between 20 and 50°. The kicks were recorded by a video camera at 50 Hz and a 2 D biomechanical analysis was conducted to obtain measures of the projection velocity and projection angle of the ball. The player’s optimum projection angle was calculated by substituting a mathematical expression for the relationship between projection velocity and projection angle into the equations for the aerodynamic flight of a rugby ball. We found that the player’s calculated optimum projection angle (30.6°, 95% confidence limits ± 1.9° was in close agreement with his preferred projection angle (mean value 30.8°, 95% confidence limits ± 2.1°. The player’s calculated optimum projection angle was also similar to projection angles previously reported for skilled rugby players. The optimum projection angle in a rugby place kick is considerably less than 45° because the projection velocity that a player can produce decreases substantially as projection angle is increased. Aerodynamic forces and the requirement to clear the crossbar have little effect on the optimum projection angle.

    Energy Technology Data Exchange (ETDEWEB)

    1978-12-01

    The objective of this report is to provide a better understanding of the institutional problems involved in the use of coal-fueled cogeneration. The viewpoints of industry, utilities, and government were probed extensively through indepth confidential interviews. To provide a real-life basis for this investigation, two existing industrial sites in the Gulf Coast area were studied. The projected effects of the installation of coal-burning cogeneration plants supplying steam and electricity to several industries, replacing existing oil and gas burning boilers, were studied for each site. This report provides insights into the overall institutional problem that will be useful at other locations. It covers the regulatory, economic, financial, engineering, operating, contractual, and corporate relations aspects of cogeneration. It concludes with suggestions for future action by the Federal government, state governments, industries, and utilities that should be helpful in removing the institutional constraints that are retarding cogeneration installations and the use of coal.

    The aim of the project is to investigate, design and increase the energy efficiency in new cogeneration/cooling systems, which are based on new developed mini gas turbines. Hereby cogeneration can primarily based on natural gas and bio-fuels be distributed to new market segments. The advantages of mini gas turbines (electric power output 20 - 250 kW) are that they have only one rotating part, are simple and small and ought to have a low specific plant price, as they are mass-produced and represent a further development based on turbo-chargers equipped with high speed generators. By means of recuperation even in small plants relatively high electric efficiency of over 30% are obtained. The biggest advantage is, however, very low operating cost, high level of reliability and small environmental impacts. Therefore, it is expected that the technology could have a large impact on new markets for small and medium-sized enterprises, resulting in renewed large-scale conversion to cogeneration. In the present project the varias conditions related to the following are investigated: 1) Use of mini gas turbine as oil-/gas burner. 2) Simple cogeneration plant with recuperation gas turbine. 3) Mini gas turbines in cogeneration/refrigerating plants for supermarkets. 4) Mini gas turbines for drying plants. 5) VOC destruction in mini gas turbines. 6) Direct driven compressors. 7) Conditions related to part load. 8) The economy of the different mini gas turbine applications. 9) Environmental issues by use of mini gas turbines.

  11. Typical off-design analytical performances of internal combustion engine cogeneration

    Xiaohong HE; Ruixian CAI

    2009-01-01

    Based on experimental data, typical off-design characteristic curves with corresponding formulas of internal combustion engine (ICE) are summarized and investigated. In combination with analytical solution of single-pressure heat recovery steam generator (HRSG) and influence of ambient pressure on combined heat and power (CHP) system, off-design operation regularities of ICE cogeneration are analyzed. The approach temperature difference Ata , relative steam production and superheated steam temperature decrease with the decrease in engine load. The total energy efficiency, equivalent exergy efficiency and economic exergy efficiency first increase and then decrease. Therefore, there exists an optimum value, corresponding to ICE best efficiency operating condition. It is worth emphasizing that Ata is likely to be negative in low load condition with high design steam parameter and low ICE design exhaust gas temperature. Compared with single shaft gas turbine cogeneration, Ata in ICE cogeneration is more likely to be negative. The main reason for this is that the gas turbine has an increased exhaust gas flow with the decrease in load; while ICE is on the contrary. Moreover, ICE power output and efficiency decrease with the decrease in ambient pressure. Hence, approach temperature difference, relative steam production and superheated steam temperature decrease rapidly while the cogeneration efficiencies decrease slightly. It is necessary to consider the influence of ambient conditions, especially the optimization of ICE performances at different places, on cogeneration performances.

    1996-09-01

    The advantages and disadvantages of simultaneous implementation of cogeneration systems and energy efficient investments were presented, together with the factors which must be present before implementing a cogeneration system. Cogeneration has been shown to be a cost-effective investment, with significant environmental benefits such as reduction of carbon emissions. It was suggested that it would be a good opportunity for businesses which have sizeable heat energy requirements to combine the concept of cogeneration, energy efficiency and open access. The combination would allow the business to sell excess electrical energy to a power pool. When planning, the electricity generation capability should be large enough to meet the needs not only of the existing facility, but also current and future electricity needs. 10 refs.

    2015-08-01

    A feasibility study was performed to assess the technical and economic merits of retrofitting biogas-based cogeneration systems to district heating networks. Three district heating plants were selected as candidates for accommodating heat recovery from nearby waste treatment stations, where a massive amount of biogas can be produced on a regular basis. The scenario involves constructing cogeneration systems in each waste treatment station and producing electricity and heat. The amounts of biogas production for each station are estimated based on the monthly treatment capacities surveyed over the most recent years. Heat produced by the cogeneration system is first consumed on site by the waste treatment system to keep the operating temperature at a proper level. If surplus heat is available, it will be transported to the nearest district heating plant. The year-round operation of the cogeneration system was simulated to estimate the electricity and heat production. We considered cost associated with the installation of the cogeneration system and piping as initial investments. Profits from selling electricity and recovering heat are counted as income, while costs associated with buying biogas are expenses. Simple payback periods of 2-10 years were projected under the current economic conditions of South Korea. We found that most of the proposed scenarios can contribute to both energy savings and environmental protection.

    In this paper, we give a relationship between projective generators (resp., injective cogen-erators) in the category of R-modules and the counterparts in the category of complexes of R-modules. As a consequence, we get that complexes of W-Gorenstein modules are actually ?W-Gorenstein com-plexes whenever W is a subcategory of R-modules satisfying W ⊥W, where ?W is the subcategory of exact complexes with all cycles in W . We also study when all cycles of a ?W-Gorenstein complexes are W-Gorenstein modules.

    This paper describes the evolution of a project that involves cogeneration of power and steam for continuous injection in oil wells in the fields of Alto do Rodrigues and Estreito, in Rio Grande do Norte, Brazil. The project combines a PETROBRAS intention for recovering heavy oil in that area with partners intention of generating power to connect in a critical point of the Brazilian Electric System. PETROBRAS studies began in the nineties, when oil wells in that area became old end showed the necessity of some oil recovery technology. In 1999, PETROBRAS and Guaraniana made a partnership for implementation of Termoacu Combined Cycle, that would begin operation as a cogeneration plant for thirteen years, and as combined cycle from that point. The profile of steam injection has been adapted to a new one to comply with the powe r capacity of the Plant, and will operate eight years as a cogeneration plant , four years as a combined cycle with cogeneration and after twelve years as a complete combined cycle with 500 MW of capacity. The project integrates a gas pipeline, a Thermal Power Plant, a Transmission Line to connect to the grid and a Steam Pipeline for steam injection at Estreito and Alto do Rodrigues fields. (author)

    Sapporo Therme is a multi-purpose resort including a hot-water jumbo swimming pool having an area of about 130,000m/sup 2/ and a circumference of 800 m, 13 additional swimming pools with additional sizes, a hot-water slider, 16 types of saunas, an artificial sunbathing system, an athletic system, a restaurant, a cinema, tennis courts, and other outdoor facilities. Sapporo Therme uses a cogeneration system consisting of using LP gas(95% or more propane gas) to drive a 1,200 PS gas engine and supply motive power and lightening. At the same time, the cogeneration system collects gas engine waste heat and combines this heat with that from hot-water and steam boilers to supply hot water to swimming pools, roads, and room heaters. The ratio of waste heat collection rate to power generation efficiency is about 5.0. Sapporo Therme is thus the optimal facilities for cogeneration. (1 figs, 3 photos)

    2000-07-01

    With its energy demand in the early 1990's growing at a high rate due to the country's strong economic growth, Malaysia studied various options to improve the efficiency of its energy use. Since its natural gas reserves are almost four times that of its crude oil reserves, efforts were therefore centered on seeking ways to boost the use of natural gas to mitigate the growing domestic energy need. PETRONAS, the national oil company, subsequently studied and chose the District Cooling System using natural gas as the primary source of fuel. The Kuala Lumpur City Center development, which houses the PETRONAS Twin Towers, was subsequently chosen as the first project to use the Gas District Cooling (GDC) System. To acquire the technology and implement this project, PETRONAS created a new subsidiary, Gas District Cooling (Malaysia) Sendirian Berhad (GDC(M)). In the process of improving the plant's efficiency, GDC(M) discovered that the GDC system's efficiency and project economics would be significantly enhanced if its is coupled to a Cogeneration system. Having proven the success of the GDC/Cogeneration system, GDC(M) embarked on a campaign to aggressively promote and seek new opportunities to implement the system, both in Malaysia-and abroad. Apart from enhancing efficiency of energy use, and providing better project economics, the GDC/Cogeneration system also is environment friendly. Today, the GDC/Cogeneration systems is the system of choice for several important developments in Malaysia, which also includes the country's prestigious projects such as the Kuala Lumpur International Airport and the New Federal Government Administrative Center in Putrajaya.

  1. Protecting Place Through Community Alliances: Haida Gwaii Responds to the Proposed Enbridge Northern Gateway Project

    Science.gov (United States)

    Crist, Valine

    This research contributes to the emerging dialogue concerning power relationships and the alliances that are challenging current frameworks in an attempt to create positive change. Worldwide, local people in rural places are threatened by development paradigms and conflicting social, political, economic, and ecological values. Large-scale development, such as the Enbridge Northern Gateway Project (NGP), provide a tangible example of our failing systems and make the interplay of these elements palpable. Increasingly, communities are coalescing to challenge the current models and economically motivated agendas threatening Indigenous sovereignty and local lifeways. Central to these coalitions are Indigenous peoples who are aligning with non-Indigenous neighbours to renegotiate power relationships. This research examines these dynamic alliances and uses Haida Gwaii's resistance to the NGP as an example of the formidable strength of community coalitions mobilized by intersecting values. To contextualize the NGP within the broader discourse, I problematize Canada's environmental assessment process and consider how media portrays the growing resistance to the proposed project. Drawing on information presented through the environmental assessment, I analyze the main messages and shared values of Haida Gwaii citizens opposed to the NGP. This thesis focuses on this unanimous and galvanizing resistance, which is largely motivated by the reliance on local food sources and an embodied connection to Haida Gwaii shared by Island citizens. The continued denial of Aboriginal title and rights was inherent throughout this consideration and is an underlying theme throughout the analyses.

    Semiconductor works, now facing declined semiconductor prices, must pursue more effective utilization of energy for cost reduction. Cogeneration systems have been attracting attention for the above purposes, and also for abatement of greenhouse effect gases, as the abatement targets have been agreed in the third session of the conference of the United Nations Framework Convention on Climate Change parties, held in Kyoto (COP3), and for satisfying the ISO14001. Fuji Electric has proposed total cogeneration systems, covering power supply from commercial lines, existing substation facilities and remote monitoring systems, and has been received an order for a 3,200 kW gas turbine cogeneration system for a new semiconductor production lines in a new building. Power and heat are secured by a commercial power line and boiler system for the existing building. For the new building, the cogeneration system supplies power and heat (steam), improving energy efficiency and, at the same time, reduces CO2 emissions. (translated by NEDO)

    Full Text Available Absorption chillers at cogeneration plants generate chilled water using steam supplied by heat recovery steam generators. The chillers can be of either single-effect or double effect configuration and the coefficient of performance (COP depends on the selection made. The COP varies from 0.7 to 1.2 depending on the types of chillers. Single effect chillers normally have COP in the range of 0.68 to 0.79. Double effect chillers COP are higher and can reach 1.2. However due to factors such as inappropriate operations and maintenance practices, COP could drop over a period of time. In this work the performances of double effect steam absorption chillers at a cogeneration plant were studied. The study revealed that during the period of eleven years of operation the COP of the chillers deteriorated from 1.25 to 0.6. Regression models on the operation data indicated that the state of deterioration was projected to persist. Hence, it would be recommended that the chillers be considered for replacement since they had already undergone a series of costly repairs.

    The contemporary situation of our environment claims the sensitive approach to solving effective conversion of energy. Limited supplies of noble fuels and their prices evoke the need to use new combustion technologies of accessible fuels in given region without negative ecological influences. Energoproject participates in the preparation of the two projects in Ostrava-Karvin{acute a} black coal field in Czech Republic. The most effective usage of fuel energy is the combined of electricity and heat. If this physical principle is supported by a pressurized fluidized bed combustion (PFBC) one obtains a high electricity/heat ratio integrated steam-gas cycle on the basis of solid fuel. Cogeneration plant Toebovice is the dominant source (600 MW{sub th}) of Ostrava district heating system (1100 MW{sub th}). The high utilization of the installed output and utilization of the clean, compact and efficient of the PFBC technology is the principal but not the single reason for the selection of the Toebovice power plant as the first cogeneration plant for installation of the PFBC in Czech Republic. The boiler will burn black coal from the neighboring coal basin.

    This guidebook focuses on cogeneration development. It is one of a series of four guidebooks recently prepared to introduce the energy developer to the federal, state and local agencies that regulate energy facilities in Idaho, Montana, Oregon, and Washington (the Bonneville Power Administration Service Territory). It was prepared specifically to help cogeneration developers obtain the permits, licenses and approvals necessary to construct and operate a cogeneration facility. The regulations, agencies and policies described herein are subject to change. Changes are likely to occur whenever energy or a project becomes a political issue, a state legislature meets, a preexisting popular or valuable land use is thought threatened, elected and appointed officials change, and new directions are imposed on states and local governments by the federal government. Accordingly, cogeneration developers should verify and continuously monitor the status of laws and rules that might affect their plans. Developers are cautioned that the regulations described herein may only be a starting point on the road to obtaining all the necessary permits.

    Full Text Available The Nasorosso project of the Italian Youth Department and the National Institute of Health, aimed to raise awareness about drinking and driving under the influence of alcohol among club goers with a series of initiatives. Within the framework of the project, blood alcohol concentration (BAC was measured on 106,406 individuals before and after clubbing in 66 different recreational sites from 11 Italian provinces, over 16 months. Participating individuals were interviewed regarding sociodemographic and environmental characteristics and alcohol intoxicated people were offered to be taken home. The BAC median at the club entry was 0.26 g/L with 65.3% subjects showing a BAC value under the driving legal limit of 0.5g/L. At the exit from clubs, BAC median value rose to 0.44 g/L and subjects with BAC value under the legal limit decreased to 54.9%. Being male, aged between 18 and 34 years with a diploma, being a drinker and entering the disco with a BAC already beyond the legal limit predicted a BAC value beyond 0.5 g/L at exit from the recreational place. Conversely, being a driver, being a student and exiting from the disco before 4 a.m. reduced the probability of having a BAC higher than 0.5 g/L at the end of the night.  Health policies to prevent harmful use of alcohol in young people should continue to offer targeted information/ prevention; in order to steadily increase the awareness of the dangers and the damages of excessive use of alcohol.

    In 1994, public hearings were held in Quebec city concerning a 120 megawatt (MW) gas cogeneration project that was to be coupled with an already existing pulp and paper mill in the downtown area. Cogeneration plants are often described as highly beneficial from the point of view of local environment. It is well known that the burning of natural gas emits far less sulfur dioxide (SO{sub 2}) and particulate matters (PM) than the combustion of oil or coal. The proposed plant would use high pressure vapour from a nearby incinerator plant and natural gas to produce low pressure vapor for the paper mill industry as well as electricity. The cogeneration plant would allow the paper mill to stop burning heavy oil. By using natural gas instead of heavy oil, the new cogeneration-paper mill complex (CPC) is expected to reinforce the recent trend and willingness towards improving downtown air quality. On the other hand, the CPC would emit more CO{sub 2}, due to the production of additional electricity. According to the Rio de Janeiro Agreement ratified in 1988, Canada is committed to stabilize its greenhouse gas emissions by the year 2000. Nevertheless, the cogeneration file is a new option considered by the Quebec Provincial Governement in its last energy triennal plan. However, it must be specified that the Province of Quebec contributes to less than 15 % of the total Canadian CO{sub 2} production although it represents more than 25 % of its population. Furthermore the maximum production of electricity by this file has been set to 250 MW. It is a very small fraction of the total production of electricity in Quebec, which is 200 TW

  13. Modeling of a Cogeneration System with a Micro Gas Turbine Operating at Partial Load Conditions

    Full Text Available The integration of absorption chillers in micro-cogeneration systems based on micro-gas turbines can be useful as an appropriate strategy to increase the total system energy efficiency. Since it is an area intensive in technology, it is necessary to develop and use models of simulation, which can predict the behavior of the whole system and of each component individually, at different operating conditions. This work is part of a research project in high efficiency cogeneration systems, whose purpose at this stage is to model a micro-cogeneration system, which is composed of a micro gas turbine, Capstone C30, a compact cross flow finned tube heat exchanger and an absorption chiller. The entire model is composed of specifically interconnected models, developed and validated for each component. The simulation of the microturbine used a thermodynamic analytic model, which contains a procedure used to obtain the micro turbine characteristic performance curves, which is closed with the thermodynamic Brayton cycle model. In the cogeneration system discussed in this paper, the compact heat exchanger was used to heat thermal oil, which drives an absorption chiller. It was designed, characterized and installed in a cogeneration system installed at the Centre d'Innovació Tecnològica en Revalorització Energètica i Refrigeració, Universtat Rovira i Virgili. Its design led to the heat exchanger model, which was coupled with the micro turbine model. Presented in this work is a comparison between the data from the model and the experiments, demonstrating good agreement between both results.

    The Federal Energy Regulatory Commission (FERC) denied Consolidated Edison's request for a rehearing on the 1981 rule which automatically qualifies new diesel and dual-fueled cogeneration facilities under sections 201 and 210 of the Public Utility Regulatory Policies Act. The petition was to return these two types of facilities on an interim exlusion status because of deficiencies in final environmental impact statements, faulty projections of the growth of cogeneration, socio-economic impacts, and tax effects. The article presents the arguments on both sides and FERC's conclusions.

    In Slovenia, approximately 2 % of electricity is generated using cogeneration systems. Industrial and district heating networks ensure the growth of such technology. Today, many existing systems are outdated, providing myriad opportunities for reconstruction. One concept for the development of households and industry envisages the construction of several small biomass units and the application of natural gas as a fuel with a relatively extensive distribution network. This concept has good development potential in Slovenia. Forests cover 56 % of the surface area in Slovenia, which has, as a result, a lot of waste wood to be turned into biomass. Biomass is an important fuel in Slovenia. Biomass is gasified in a gasifier, and the wood gas obtained is used to power the gas engine. This paper describes a biomass cogeneration system as the first of this type in Slovenia, located in Ruše.

    2000-07-01

    The Japan Gas Association is developing ceramic gas engines (CGE) for use in co-generation systems driven by natural gas. Ceramic gas engines are lightweight, compact power units with high power generation efficiency, enabling a high level of waste heat utilization from the hot exhaust. Although the Japanese office building market has the potential of becoming a major market for co-generation systems, the heat-electricity ratio of such facilities (with a significantly large electricity demand in comparison to the heat demand) renders conventional co-generation systems unsuitable for application to office buildings. The newly-developed engine system should allow this previously unexplored market to be exploited. Development of the engine system was initiated in 1993, and has now entered its seventh year. This report describes the current development status of the CGE technology. Development of the engine was funded as an auxiliary project by the Ministry of International Trade. and Industry (MITI) from 1993 through 1999, after which activities will continue within the private sector.

    In this work a technical and economical analysis of the installation of a reverse osmosis desalting plant connected to a power station that uses the combined cycle technology under a co-generation scheme is presented: production of electricity and water. The operation program of the desalting power station will be determined by the demand of energy of the combined cycle power station; the proposal is that the desalting plant operates in the hours of low load of the power station and shuts down at the peak hours of electrical energy demand. So that this study is representative, the demand curves of electric energy of the units of combined cycle of Central President Juarez Rosarito of the Comision Federal de Electricidad (CFE) have been taken and updated the data of the reverse osmosis desalting plants that are available at the moment in the market. As basis of the study the level costs will be determined so much as the electrical energy generated by the power station of combined cycle, operating inside and outside of a co-generation scheme and the costs made level for the water produced by the reverse osmosis plant under two assumptions: the first one is buying the electrical energy from CFE and the second one considering that the CFE is the owner of the desalting plant and therefore the cost of electrical energy to desalting the plant is zero. This work shows the economic impacts on the costs of the generation of electrical energy and on those of the desalted water in a co-generation scheme. The results shown in this study can be considered for the future planning in the construction of desalting plants to supply of water in the Northwestern zones of the country where serious problems of water shortage exist.

    Like most developing countries, Nigeria is looking to cogeneration as a sustainable and reliable means of overcoming its present unreliable supply of energy. The article focuses on the efforts of the food company Cadbury Nigeria which uses cogeneration for all its steam and power requirements within its own factory. The Company recently decided to upgrade further by switching from liquid fossil fuels to natural gas. Diagrams show the existing system as well as the systems for cogeneration with natural gas. Some of the obstacles to be overcome to improve the viability of cogeneration in developing countries are listed. It is hoped that the outcome of the COP6 meeting to be held in April 2001 will offer encouragement for cogeneration.

    Energy policy of the European Community is implemented by setting various goals in directives and developing support mechanisms to achieve them. However, very often these policies and legislation come into contradiction with each other, for example Directive 2009/28/EC on the promotion of the use of energy from renewable sources and Directive 2012/27/EU on energy efficiency, repealing Directive 2004/8/EC on the promotion of cogeneration based on a useful heat demand. In this paper, the authors attempt to assess the potential conflicts between policy political objectives to increase the share of high-efficiency co-generation and renewable energy sources (RES), based on the example of Riga district heating system (DHS). If a new heat source using biomass is built on the right bank of Riga DHS to increase the share of RES, the society could overpay for additional heat production capacities, such as a decrease in the loading of existing generating units, thereby contributing to an inefficient use of existing capacity. As a result, the following negative consequences may arise: 1) a decrease in primary energy savings (PES) from high-efficiency cogeneration in Riga DHS, 2) an increase in greenhouse gas (GHG) emissions in the Baltic region, 3) the worsening security situation of electricity supply in the Latvian power system, 4) an increase in the electricity market price in the Lithuanian and Latvian price areas of Nord Pool power exchange. Within the framework of the research, calculations of PES and GHG emission volumes have been performed for the existing situation and for the situation with heat source, using biomass. The effect of construction of biomass heat source on power capacity balances and Nord Pool electricity prices has been evaluated.

    Coal is widely used all over the world in almost all power plants. The dependence on coal has increased enormously as the demand for electricity has reached its peak. Coal being a non-renewable source is depleting fast. We being the engineers, it's our duty to conserve the natural resources and optimize the coal consumption. In this project, we have tried to optimize the bio-mass utilization in high pressure cogeneration boiler. The project was carried in Seshasayee Paper and Boards Limited, erode related to Boiler No:10 operating at steam pressure of 105 kscg and temperature of 510°C. Available bio-mass fuels in and around the mill premises are bagasse, bagasse pith, cane trash and chipper dust. In this project, we have found out the coal equivalent replacement by the above bio-mass fuel(s) to facilitate deciding on the optimized quantity of coal that can be replaced by biomass without modifying the existing design of the plant. The dominant fuel (coal) which could be displaced with the substitute biomass fuel had been individually (biomass) analyzed.

    The Directive on ''the promotion of cogeneration based on a useful heat demand in the internal energy market'' should be adopted very soon. The initial aim of the Directive is to strengthen existing measures to promote CHP in line with the Community target of doubling the share of CHP in EU electricity generation from 9% in 1994 to 18% by 2010. But no target has been mentioned. Energie-Cites states, in this document, its opinion of this draft proposal. Cogeneration is a well-tried and proven technology which has achieved tangible results and is one of the more efficient ways for the EU to fulfill the commitments it made under the Kyoto Protocol.

    Thermal systems are essential in facilities such as thermoelectric plants, cogeneration plants, refrigeration systems and air conditioning, among others, in which much of the energy consumed by humanity is processed. In a world with finite natural sources of fuels and growing energy demand, issues related with thermal system design, such as cost estimative, design complexity, environmental protection and optimization are becoming increasingly important. Therefore the need to understand the mechanisms that degrade energy, improve energy sources use, reduce environmental impacts and also reduce project, operation and maintenance costs. In recent years, a consistent development of procedures and techniques for computational design of thermal systems has occurred. In this context, the fundamental objective of this study is a performance comparative analysis of structural and parametric optimization of a cogeneration system using stochastic methods: genetic algorithm and simulated annealing. This research work uses a superstructure, modelled in a process simulator, IPSEpro of SimTech, in which the appropriate design case studied options are included. Accordingly, the cogeneration system optimal configuration is determined as a consequence of the optimization process, restricted within the configuration options included in the superstructure. The optimization routines are written in MsExcel Visual Basic, in order to work perfectly coupled to the simulator process. At the end of the optimization process, the system optimal configuration, given the characteristics of each specific problem, should be defined. (author)

    Cogeneration, or combined heat and power, is the use of a heat engine or a power station to simultaneously generate both electricity and useful heat generally in the form of steam or hot water. By capturing the excess heat, it uses thermal energy that would be wasted in a conventional power plant, provides high energy conversion efficiency, and also reduces emissions. Exergy analysis has been found to be an effective tool for predicting the efficiencies of system components and the total thermodynamic effectiveness of the system, as well as for highlighting possible improvements. By using both exergy concepts and economics, an exergoeconomic analysis is possible which helps designers to find ways to improve the performance of a system in a cost effective way. This study presents the exergoeconomic analysis of a cogeneration plant at Erdemir, Turkey. The mass, energy and exergy balances were done, and the exergoeconomic analysis of the plant, with a 39.5 MW electricity total net power and 20.83 kg/s steam production capacity, was also done.

    Full Text Available The integration of cogeneration systems in residential and mixed-use communities has the potential of reducing their energy demand and harmful emissions and can thus play asignificant role in increasing their environmental sustainability. This study investigated the impact of selected planning and architectural design parameters on the environmental and economic performances of centralized cogeneration systems integrated into residential communities in U.S.cold climates. Parameters investigated include: 1 density, 2 use mix, 3 street configuration, 4 housing typology, 5 envelope and building systems’ efficiencies, and 6 passive solar energyutilization. The study integrated several simulation tools into a procedure to assess the impact of each design parameter on the cogeneration system performance. This assessment procedure included: developing a base-line model representing typical design characteristics of U.S. residential communities; assessing the cogeneration system’s performance within this model using three performance indicators: percentage of reduction in primary energy use, percentage of reduction in CO2 emissions; and internal rate of return; assessing the impact of each parameter on the system performance through developing 46 design variations of the base-line model representing potential changes in each parameter and calculating the three indicators for each variation; and finally, using a multi-attribute decision analysis methodology to evaluate the relative impact of each parameter on the cogeneration system performance. The study results show that planning parameters had a higher impact on the cogeneration system performance than architectural ones. Also, a significant correlation was found between design characteristics identified as favorable for the cogeneration system performance and those of sustainable residential communities. These include high densities, high use mix, interconnected street networks, and mixing of

    Gas turbines are widely used for power generation. In cogeneration system, the gas turbine generates electricity and the exhaust heat from the gas turbine is used to generate steam or chilled water. Besides enhancing the efficiency of the system, the process assists in reducing the emission of CO2 to the environment. This study analyzes the amount of CO2 emission by Universiti Teknologi Petronas gas fuelled cogeneration system using energy balance equations. The results indicate that the cogeneration system reduces the CO2 emission to the environment by 60%. This finding could encourage the power plant owners to install heat recovery systems to their respective plants.

    Cogeneration of heat and power (CHP) is undeniably the environmentally most favourable way of making efficient use of energy in the power generation industry. Cogeneration is also particularly appreciated by political decision makers because of its high yield from primary energy sources, and thus its contribution to the protection of the environment and the conservation of resources. Advanced gas turbines, along with an intelligent power plant design consisting of pre-engineered, modular power plant items, will help cogeneration to play an important role in future energy markets also from an economic point of view.

    Winegrapes (Vitis vinifera L) are the most valuable horticultural crop in the world with nearly eight million hectares of vineyards in cultivation. Different varieties of winegrapes (e.g., Grenache or Syrah) exhibit an unprecedented amount of phenological and genetic diversity for a cultivated species, which is an important resource to buffer against climate change. Matching phenological strategies of the different winegrape varieties to a particular climate is a fundamental aim for every vineyard manager, especially in the face of significant climatic shifts in many winegrape growing regions. Yet current projections of suitable winegrape growing regions based on future climate scenarios are limited in their utility, as they do not consider the possibility that other varieties better suited to a future climate could be planted within an existing region. For our projections, we built phenological models for the nine most-planted winegrapes globally, which constitutes over 40% of all planted hectares, using a global dataset of budburst, flowering, veraison and maturity. These models were then used to characterize the growing range of 1300 globally planted winegrape varieties. Combing these models with climate projection models under RCP 4.5 and 8.5 emission scenarios we examined future distributions of suitable wine growing regions, as well as the turnover of suitable varieties within existing regions. In some regions of the world, predicted climate change will not significantly alter the varieties that are able to grow, while in others there will need to be shifts in the region itself or in the varieties that are currently planted. Some regions will also see a significant increase in the number and diversity of varieties that can be grown. Our results suggest the need to utilize the full range of winegrape diversity available when considering adaptive strategies in response to changing climates.

    Transdisciplinary education on sustainability for health has been primarily developed in high-income countries, yet the need in countries with limited research and human resource investments remains urgent. Little empiric documentation of the facilitators and barriers to transdisciplinary learning in such countries has been described. We assessed transdisciplinary learning among students of different disciplines collaborating with an Ecuadorian sustainability for health research project. Six undergraduate students from four different disciplinary backgrounds were incorporated through work-study agreements with provincial university academic supervisors. Learning was fostered and monitored through participant observations by a field supervisor. Students' learning was evaluated through subsequent in-depth interviews and visualization methods. Academic supervisor key informant and co-investigator observations aided triangulation. Qualitative data were analyzed using indicators of transdisciplinary thinking. Principal factors facilitating transdisciplinary learning were interaction with social actors, the integration of work with other disciplines, the use of alternative research techniques and methods, and the constant support of the field supervisor. Inhibiting factors included the existence of rigid academic rules, lack of training of the academic supervisors in diverse research methods, and social pressures to implement unidisciplinary foci. At the end of their link with the project, students had developed both cognitive outcomes and attitudinal values relevant to sustainable development for health. In countries with limited investments in research and human resources development, transdisciplinary approaches with social actors and engaged researchers can sensitize new professionals training in traditional academic contexts to the ecological-social-health problems faced by poor majorities and encourage their subsequent work on sustainability for human health.

    Expansion of the cruise ship terminal at the offshore end of Canada Place is described, with particular emphasis on soil conditions which influenced foundation design for the 10,000 sq m pile-supported deck and the associated ground improvement measures required to assure public health and safety. To provide the required ground improvements, vibro-densification of the existing granular fill and self-feeding of gravel into the silt unit were utilized offshore of the existing apron. The objective here was to make the loose granular fill denser in order to make it non-liquefiable and to strengthen or stiffen the underlying silt unit to minimize earthquake-induced displacements. Under the apron surrounding the existing structure, 145 seismic drains were installed into the granular fill to a depth of 13 m. The purpose of these seismic drains is to prevent liquefaction. The expanded terminal facility will provide additional cruise ship berthing and visitor facilities on a pile-supported deck structure.

    There is a large potential for nuclear energy also in the non-electric heat market. Many industrial sectors have a high demand for process heat and steam at various levels of temperature and pressure to be provided for desalination of seawater, district heating, or chemical processes. The future generation of nuclear plants will be capable to enter the wide field of cogeneration of heat and power (CHP), to reduce waste heat and to increase efficiency. This requires an adjustment to multiple needs of the customers in terms of size and application. All Generation-IV concepts proposed are designed for coolant outlet temperatures above 500 C, which allow applications in the low and medium temperature range. A VHTR would even be able to cover the whole temperature range up to approx. 1 000 C.

    Highlights: • HTR feasibility for process heat cogeneration is assessed. • A cogeneration coupling for HTR is proposed and process heat cost is evaluated. • A CCGT process heat cogeneration set up is also assessed. • Technical comparison between both sources of cogeneration is performed. • Economical competitiveness of the HTR for process heat cogeneration is analyzed. - Abstract: High temperature nuclear reactors offer the possibility to generate process heat that could be used in the oil industry, particularly in refineries for gasoline production. These technologies are still under development and none of them has shown how this can be possible and what will be the penalty in electricity generation to have this additional product and if the cost of this subproduct will be competitive with other alternatives. The current study assesses the likeliness of generating process heat from Pebble Bed Modular Reactor to be used for a refinery showing different plant balances and alternatives to produce and use that process heat. An actual practical example is presented to demonstrate the cogeneration viability using the fact that the PBMR is a modular small reactor where the cycle configuration to transport the heat of the reactor to the process plant plays an important role in the cycle efficiency and in the plant economics. The results of this study show that the PBMR would be most competitive when capital discount rates are low (5%), carbon prices are high (>30 US$/ton), and competing natural gas prices are at least 8 US$/mmBTU.

    In this paper, the contribution to the financial and economic feasibility of cogeneration systems with gas turbine and exhaust gas heat recovery boiler is discussed in function of the financial credit for reduction of greenhouse gases emissions (GH Gs) by using the Clean Development Mechanism (CDM). It has to be kept in mind the restrictions of these systems to be capital intensive projects subject to the effects of the economy of scale. Other factors to take into account are the constancy of the heat demand, the rates of sale of electricity and steam surpluses, the regulatory laws, the ignorance of the cogeneration technologies on the part of the investor, among others. The profitability of the investment for implementation of a cogeneration system can be elevated in large facilities with gas turbines and heat recovery boiler (T G + HRSG). Results discussed in previous papers are pointed out and new conclusions are enunciated. (author)

    It is never too early to bring in your own research into teaching. Considerable efforts have been made globally to introduce STEM research themes in K12 environments. These efforts a laudable as they help to create STEM identity in students and get students excited to pursue higher education. The task of a post-secondary educator is to build on that excitement and ensure that the students who enter higher education come out knowledgeable, skilled, and employable. At the University of Alaska Fairbanks we have structured our geospatial curricula to include place-based, independent research projects in several semester-long classes. These class-projects serve as mini capstone research experiences that take a student through the entire process of research including: identifying a problem or need; building a hypothesis; formulating the science question; searching, acquiring, and processing data; analyzing and interpreting the research results; and presenting the outcomes in written and oral format to a peer group. Over a decade of experience has shown that students tend to engage and perform well when the research addresses an authentic problem they can relate to and take ownership of. Over 150 student-lead class projects using a variety of freely available datasets have contributed not only to preparing the future workforce, but also to enhancing the research profile of UAF. We extended the same model to a summer internship program where graduate students who have gone through the experience of an in-class research project serve as mentors for undergraduate interns. Even the condensed time frame yields positive outcomes including joint publications between faculty, staff, graduate students and undergraduate students in the peer-reviewed literature.

    The 2008 financial crisis has left traces in the built environment of Copenhagen like many other places: Building projects are left unfinished or their function or finish is changed due to new economic circumstances. An ethnographic exploration of these traces exposes central aspects of what...... is at stake, when we design the places we inhabit. In the process of design we engage with our material surroundings and seek to shape them according to our ideals. However, the market forces also play a key role in shaping these places, and these forces cannot be controlled. Rather, they are dealt with much...... like the forces of nature. Based on a fieldwork in three new housing developments in Copenhagen, this paper aims to bring the financial crisis ‘down to earth’ by examining the material shapes it has taken in the spaces of everyday life.

    Kameda, H. (Showa Shell Sekiyu K.K., Tokyo (Japan))

    1994-03-31

    This paper introduces a cogeneration system at the Showa Shell Sagamihara Shopping Center. The Center assumes a peak power demand of 4000 kW, thereby using utility power (not connected to the cogeneration system) at 2000 kW, and generating power by using three 1000-kW diesel engine generators. The waste heat utilizing facility consists of three steam waste heat boilers with a capacity of 614 kg/h and a pressure of 9 kg/cm[sup 2]. The steam is used as a heat source for absorption type freezers, and to recover hot water through plate-type heat exchangers. Two after-burning boilers of 2.5 tons/hour are also used to supplement shortage of steam at power peaks for room cooling with the number of boilers adjusted. The absorption-type freezer consists of two steam double-effect 500RTs which perform air conditioning by circulating cold water. A 150 RT motor-driven turbo freezer has also been installed to cover peak power demand in the summer season. All the facilities have been installed in the basement to minimize influence of vibration and noise to the surrounding districts. NOx emission has been suppressed to 400 ppm or lower by means of ammonia reducing denitrification. Low-sulfur heavy oil A is used to reduce SOx emission. The Center has obtained a specific supply permission to supply excess power of 2850 kW after in-house consumption of the power generated in the cogeneration system to the tenant shops in the Center. 7 figs., 2 tabs.

    A description of a cogeneration plant in San Juan del Rio, Mexico was presented. The Arancia-Corn Products, S.A. de C.V. corn processing plant makes use of an aero-derivative gas turbogenerator and a heat recovery boiler. The total installed capacity at the plant is 17.5 MW. The project was first considered when the plant production capacity nearly tripled, thereby increasing the need for electrical energy. The cogeneration project, which went into production in December 1996 makes use of the considerable amounts of steam from the plants operation. There is also the possibility of wheeling electric energy to other plants owned by the same company. The authorities involved in the project are the Mexican Ministry of Energy, Comision Reguladora de Energia, Petroleos Mexicanos (which supplied the natural gas), Comision Federal de Electricidad, and other federal, state and local authorities. A review of the permits and contracts that made up the agreement was also included. 2 figs.

    The economic and environmental benefits of energy efficiency were discussed with reference to district energy and distributed generation/cogeneration. The Canadian Energy Efficiency Alliance is a leading independent organization which promotes energy efficiency and its benefits to the economy and the environment. Members include utilities, manufacturers, energy consultants, consumers and environmental groups across Canada. The Alliance mobilizes support for government policies, programs and standards. It also monitors and reports on government activities to raise a public profile of energy efficiency. This presentation includes a report card of the environmental performance of the provincial and federal governments in Canada which provides an indication of the level of their commitment to incorporate energy efficiency measures in their policy processes. Quebec and the Yukon share top honours for their initiatives on energy efficiency. The direct benefits of energy efficiency include reduced energy bills for customers, reduced carbon dioxide emissions, and greater efficiency of the supply system. Indirect benefits include job creation, the advancement of new technologies and enhanced energy security. Between 1990 and 1999 energy efficiency initiatives in Canada resulted in an 8 per cent reduction. Overall energy usage increased 12 per cent. Distributed generation consists of small-scale, modular power generation units located in proximity to where the energy is used. Cogeneration is the combined production of heat (usually as steam) and electricity, where both products are used. Since district energy often makes use of steam or hot water it can be part of a cogeneration system and a cogeneration-based district energy qualifies as distributed generation. Cogeneration produces about one third of the carbon dioxide emissions compared to power produced from coal and heat from natural gas. Distributed generation results in reduced electricity transmission and

    This work presents the methodology for analysis of generation/cogeneration projects in NGV filling stations, determining the influence of critical parameters in its technical-economic viability. To achieve this methodology, it was necessary to define parameters that influence directly or indirectly the size of a generating system, as the total electric demand of the filling station, ratio (power of the compressor) / (total installed power), load factor, factor of simultaneity, technical data of major equipment, among others. The methodology has been validated by comparing with data measured in a NGV filling station and allows screening and identifying customers with technical feasibility to evolve in a generation or cogeneration project. The cogeneration with NG generators was highlighted during the analysis of the NGV filling stations and was feasible for establishments which have large thermal demand, as filling stations along the road with large amounts of electric showers in changing rooms.

Three basic technologies for recovering energy from MSW are considered, namely: direct combustion using a waterwall incinerator in which heat from burning refuse is converted to steam by circulating water in steel tubes jacketing the interior of the incinerator; manufacture of a relatively uniform shredded, pulverized, or pelleted refuse-derived fuel for supplemental firing in a utility boiler; and pyrolysis or destructive distillation of MSW to extract a low-Btu fuel gas. While resource and energy recovery systems can be installed independently, the processes described here include both energy and resource-recovery systems as well as necessary pollution-control equipment for gaseous emissions. Three end-use applications of cogeneration systems are characterized, including: fluidized-bed cogeneration systems for use in the pulp and paper industry; diesel system using the digested sewage gas of a sewage treatment plant for electricity generation as well as heating and pumping; and an enhanced oil recovery system. Comparisons are made of system inputs per 10/sup 12/ Btu steam output for Landguard pyrolysis, Garrett flash pyrolysis, Union Carbide Purox process, direct combustion, refuse-derived fuels, fluidized-bed cogeneration, diesel cogeneration, and enhanced oil recovery (cogeneration). The RFD system is by far the cheapest to build and is also the most efficient in terms of energy recovery per ton of MSW. The fluidized-bed system has the highest overall system efficiency. However, the PUROX system uses the least ancillary energy and is the only system not requiring an input water flow. Thus the RFD is the most favorable for capital inputs and the PUROX is the most favorable for operational inputs.

    This paper presents the comparative exergy and thermoeconomic analysis of three cogeneration systems designed for a chemical plant. These systems must produce steam and electricity for the processes of the plant. These comparisons are developed for two scenarios: in the first one the systems generate steam and electricity for the plant and in the second one the systems generate steam and electricity for the plant and export electricity. The cogeneration systems are: a steam cycle with condensation-extraction steam turbine, a gas turbine based system and a combined cycle based system.

    The exergy analysis developed for the cogeneration systems evaluates the exergy efficiency and the exergy destroyed in each set of equipment, as well as the overall cogeneration plant performance. The overall exergy efficiency of the plants and the exergy efficiency of each set of equipment are defined as the ratio of the useful exergetic effect of the equipment/system to the consumed exergy. The importance of each set of equipment in the overall exergy efficiency is quantified by the use of the factor f, defined as the ratio of the supplied exergy in a particular set of equipment to the consumed exergy in the plant. Equality and extraction cost partition methods are utilised (in the steam and gas turbines in order to determine the production costs of steam (at 6 and 18 bar and electricity, for each one of the considered operating scenarios of the plants. This comparison indicates the feasibility of the cogeneration systems for each production scenario.

    Because the by-product heat from a power-conversion process is captured for productive use in a cogeneration system, instead of exhausted to the environment as it is in a conventional power plant, cogeneration represents an important energy-conservation technique. By cogenerating, an industrial plant can save the fuel that would have been needed to produce the amount of heat captured. Recognizing the significant energy-savings potential offered by cogeneration, DOE has undertaken a major R, D, and D program to investigate and promote cogeneration in industry. Resource Planning Associates, Inc. (RPA), has been working to accomplish four of the program's objectives: (1) survey current, near state-of-the-art, and future cogeneration equipment, and identify any gaps or deficiencies; (2) characterize the energy requirements of the manufacturing sectors of five of the country's most energy-intensive industries - chemical, petroleum refining, paper and pulp, textiles, and food; (3) identify principal targets for, and barriers to, the increased market development of cogeneration systems; and (4) estimate the potential maximum and the probable energy savings that could be achieved in the five selected industries through cogeneration. In investigating cogeneration hardware, three specific technologies - steam turbines, gas turbines, and diesel engines - were emphasized. It is estimated that the widespread application of cogeneration technology in the five industries studied could result in a maximum potential savings of 2.4 million barrels of oil equivalent per day (or a maximum incremental capacity of 140,000 MWe) by 1985.

    .06 MW cogeneration plant, to be run on natural gas, to meet about 30% of the facility's current demand for electricity and heat. In order to anticipate the environmental consequences of this CHP project, an environmental impact assessment (EIA) was conducted, according to the principles that apply in New Brunswick (Regulation 87-83 on EIA). A literature review was conducted and a matrix approach (matrix of impacts) was used to identify and assess the anticipated environmental impacts. The study showed that multiple stakeholders in the healthcare sector can reap benefits of CHP deployment. Facility owners can reduce energy costs and increase power reliability to enhance operations' continuity, during normal and extraordinary times (e.g., natural disasters). For instance, when hurricanes Katrina and Rita struck the United States in 2005, hospitals running with CHP were able to provide secure electricity supplies for emergency facilities and shelters. CHP also has environmental benefits related to its distinctively high efficiency. But its deployment in the healthcare sector also provides challenges, mainly due to the fact that power production is not a core activity for an hospital. These challenges can be overcome, however, as shown by numerous success stories in hospitals worldwide; specialised resources are available to help hospitals switch to CHP. This study underlines some of the steps a hospital can take toward this aim. EIA of The Moncton Hospital CHP project suggests that, globally, the environmental impacts of CHP are reduced compared to the traditional production of electricity and heat separately. Cogeneration utilizes fewer resources (fuel) and therefore releases fewer GHG and other pollutants. However, quantifying the emissions avoided is challenging. Also, the environmental benefits of CHP may be less obvious when compared to a centralised nuclear or hydraulic power production, which emits less GHG than power plants operating on coal or fuel oil.

    There is a rising interest in Sweden for the use of cogeneration power plants in district heating networks, generating both electricity and heat in a coupled operation. This type of cogeneration needs, however, the existence of suitable heat loads. In this study we investigate the use of large long-term heat storages for the cases that the DH-load is not sufficient. For this purpose, the technology of long-term storages is also reviewed based on the know-how developed for solar heating plants at the end of 20th century. Long-term storages have been developed around the 1980s and 1990s. The storages have been built as pits in the ground or as caverns for the storage of hot water or as borehole storages and aquifers for heat storages in rock or ground material. In this report, the different techniques are described and operational experiences from Sweden and Germany are summarised. Furthermore, the storage costs for the different techniques are presented. In order to be of interest for application in cogeneration systems, it is necessary that the storage allows charging and discharging with high heat capacities. The most suitable storage type for that purpose is a rock cavern, which can be constructed in volumes up to millions of m3 water with reasonable costs, as demonstrated in the 1970s with strategic oil storages. Another interesting storage type is the borehole ground storage, as used in solar heating plants. However, in the application for cogeneration, this storage type must be further developed towards higher heat transfer rates. For the analysis of storage applications in cogeneration systems, a number of operational cases from real cogeneration systems in Enkoeping and in Linkoeping have been studied. Models have been developed for calculation in Excel and operational years have been simulated and economically evaluated with different storage sizes. The following basic systems have been analysed: a) System with biofuel-fired cogeneration and biofuel top

    What is cogeneration and how does it reduce costs? Cogeneration is the production of power -- and useful heat -- from the same fuel. In a typical biomass-fueled cogeneration plant, a steam turbine drives a generator, producing electricity. The plant uses steam from the turbine for heating, drying, or other uses. The benefits of cogeneration can mostly easily be seen through actual samples. For example, cogeneration fits well with the operation of sawmills. Sawmills can produce more steam from their waste wood than they need for drying lumber. Wood waste is a disposal problem unless the sawmill converts it to energy. The case studies in Section 8 illustrate some pluses and minuses of cogeneration. The electricity from the cogeneration plant can do more than meet the in-house requirements of the mill or manufacturing plant. PURPA -- the Public Utilities Regulatory Policies Act of 1978 -- allows a cogenerator to sell power to a utility and make money on the excess power it produces. It requires the utility to buy the power at a fair price -- the utility`s {open_quotes}avoided cost.{close_quotes} This can help make operation of a cogeneration plant practical.

    A site-specific conceptual design and evaluation of a solar central receiver system integrated with an existing cogeneration facility are described. The system generates electricity and delivers a portion of that electricity and process steam to a natural gas processing plant. Early in the project, tradeoff studies were performed to establish key system characteristics. As a result of these studies the use of energy storage was eliminated, the size of the solar facility was established at 37.13 MW (sub t), and other site-specific features were selected. The conceptual design addressed critical components and system interfaces. The result is a hybrid solar/fossil central receiver facility which utilizes a collector system of Department of Energy second generation heliostats.

    The principal objective of this work is to develop a calculation process, based on the second law of thermodynamics, for evaluating the thermoeconomic potential of a small steam cogeneration plant using waste from pulp processing and/or sawmills as fuel. Four different configurations are presented and assessed. The exergetic efficiency of the cycles that use condensing turbines is found to be around 11%, which has almost 3 percent higher efficiency than cycles with back pressure turbines. The thermoeconomic equations used in this paper estimated the production costs varying the fuel price. The main results show that present cost of technologies in a small-scale steam cycle cogeneration do not justify the implementation of more efficient systems for biomass prices less than 100 R$/t.

    In thermoelectric application, it is widely known that the material limitation has still been the chief barrier of lifting its application to a higher level. Continuous efforts are extensively being made in developing novel material structures and constructions for thermoelectric modules with higher conversion efficiency. However, the overall system efficiency, which is one of the major parameters that most of the engineer and users care about, is not only ruled by the properties of applied thermoelectric materials, but also decided by the design of heat exchangers used on both sides of thermoelectric modules. Focusing on the cooling capacity and hydraulic characteristics of heat exchanger, this paper introduces an oriented cooling method for the domestic thermoelectric cogeneration, which delivers system efficiency up to 80%. This purpose-oriented cooling plate is designed for thermoelectric cogeneration for the residential houses installed with boiler or other heating facilities with a considerable amount of unused heat. The design enables Thermoelectric Cogeneration System (TCS) to be flexibly integrated into the existing hydraulic system. The mathematical model for the cooling plate has been established for a well understanding at the theoretical level. The performance of cooling plate has been investigated in a series of experimental studies which have been conducted under different coolant inlet velocity and temperature. The economic operating zone in which a good system performance could be achieved has been discussed and identified for the current configuration.

    A description of a cogeneration plant in San Juan del Rio, Mexico was presented. The Arancia-Corn Products, S.A. de C.V. corn processing plant makes use of an aero-derivative gas turbogenerator and a heat recovery boiler. The total installed capacity at the plant is 17.5 MW. The project was first considered when the plant production capacity nearly tripled, thereby increasing the need for electrical energy. The cogeneration project, which went into production in December 1996 makes use of the considerable amounts of steam from the plants operation. There is also the possibility of wheeling electric energy to other plants owned by the same company. The authorities involved in the project are the Mexican Ministry of Energy, Comision Reguladora de Energia, Petroleos Mexicanos (which supplied the natural gas), Comision Federal de Electricidad, and other federal, state and local authorities.

    Extreme social and cognitive deprivation as a result of institutional care has profound effects on developmental outcomes across multiple domains for many abandoned or orphaned children. The Bucharest Early Intervention Project (BEIP) examines the outcomes for children originally placed in institutions who were assessed comprehensively and then randomized to foster care (FCG) or care as usual (CAUG) and followed longitudinally. Here we report on the brain electrical activity (electroencephalogram: EEG) of 12-year-old children enrolled in the BEIP. Previous reports suggested improvement in resting EEG activity for the group of children placed in the foster care intervention, particularly those placed before 24 months of age compared to children who were randomized to CAUG or those placed into families after this age. At 12 years, differences between those in the FCG and those in the CAUG persist in the alpha band (8-13 Hz), but not in higher frequency bands (i.e. in the beta band; 15-30 Hz), except in those children placed into the FCG who remained in high quality care environments over the course of the study. These findings highlight the importance of maintaining a stable high quality caregiving environment, particularly for children exposed to early psychosocial deprivation, for promoting healthy brain development.

    2009-06-15

    Hazardous comparisons and assumptions are being used in public campaigns aimed at selling cogeneration as a universal remedy for greater energy efficiency and climate protection. Example calculations and arguments to this end originate in particular from the Bundesverband Kraft-Waermekopplung e.V. (BKWK - German Cogeneration Association) in Berlin and the Arbeitsgemeinschaft fuer Waerme und Heizkraftwirtschaft e.V. (AGFW - Working Group for Heat and Cogeneration) in Frankfurt on the Main in their ''Branchenreport 2007''. This article undertakes a detailed analysis of these representations. It shows that under the line the advantage of cogeneration over the separate generation of electricity and heat does not come to much. It therefore appears advisable to rethink the campaigns for cogeneration being waged in politics and industry ahead of the next energy and climate packages.

    1982-10-01

    The thermal economic feasibility of a small cogenerated energy facility designed to serve several industries in the Stockyards area was investigated. Cogeneration options included two dual fuel diesels and two gas turbines, all with waste heat boilers, and five fired boilers. Fuels included natural gas, and for the fired boiler cases, also low sulphur coal and municipal refuse. For coal and refuse, the option of steam only without cogeneration was also assessed. The fired boiler cogeneration systems employed back pressure steam turbines. The refuse fired cases utilized electrical capacities, 8500 to 52,400 lbm/hr and 0 to 9.9 MW (e), respectively. Deficient steam was assumed generated independently in existing equipment. Excess electrical power over that which was displaced was sold to Commonwealth Edison Company under PURPA (Public Utility Regulatory Policies Act). The facility was operated by a mutually owned corporation formed by the cogenerated power users.

    Establishing topographical maps of the external world is an important but still poorly understood feature of the vertebrate sensory system. To study the selective innervation of hindbrain regions by sensory afferents in the zebrafish embryo, we mapped the fine-grained topographical representation of sensory projections at the central level by specific photoconversion of sensory neurons. Sensory ganglia located anteriorly project more medially than do ganglia located posteriorly, and this relates to the order of sensory ganglion differentiation. By single-plane illumination microscopy (SPIM) in vivo imaging, we show that (1) the sequence of arrival of cranial ganglion inputs predicts the topography of central projections, and (2) delaminated neuroblasts differentiate in close contact with the neural tube, and they never loose contact with the neural ectoderm. Afferent entrance points are established by plasma membrane interactions between primary differentiated peripheral sensory neurons and neural tube border cells with the cooperation of neural crest cells. These first contacts remain during ensuing morphological growth to establish pioneer axons. Neural crest cells and repulsive slit1/robo2 signals then guide axons from later-differentiating neurons toward the neural tube. Thus, this study proposes a new model by which the topographical representation of cranial sensory ganglia is established by entrance order, with the entry points determined by cell contact between the sensory ganglion cell bodies and the hindbrain.

    The growing preoccupation for the environment in our country and its interest to ratify the Kyoto Protocol with respect to the contamination of the atmosphere, offers great opportunities for the cogeneration so that it fortifies the scientific and technological research and gives a good international image about the sustainable development and care of the environment, so that companies that invest in clean technology will be able to assign a monetary value to their environmental patrimony, this through the so called Green Bonds or Carbon Bonds, this opens a new dimension to finance projects by means of these bonds that can be negotiated at an international level; by means of the Clean of Energy Production the investment can be stimulated and revenues for projects that contribute to the sustainable development of the country and the power efficiency. At the moment the country has at least 13 projects in different analysis stages to enter the carbon bond market, which are presented as co-generation projects of energy, in addition to the formation of the Mexican Committee for Projects of Reduction and Capture of Gas Discharges of Greenhouse Effect.

    The German government aim at power generation from cogeneration up to 25% until 2020. The financing of cogeneration plants will be newly arranged for this aim: 1st September has started up financing for mini-cogeneration plants up to 50 kW. Otherwise at 1st January 2009 a novel of cogeneration law will become effective. (orig./GL)

    Substantial energy savings can be made in the tertiary sector thanks to the implementation of cogeneration systems. The 'grafting' of a cogeneration system to an existing space heating installation requires to take some precautions which are explained in this technical article using a real example. In particular, it shows why, despite some visible improvements, some installations can suffer from a lack of performance. (J.S.)

  15. Algorithms for short-term production planning of cogeneration plants

    Energy Technology Data Exchange (ETDEWEB)

    Dotzauer, E.

    1998-03-01

    A cogeneration plant, feeding its output water into a district-heating network, may include several types of energy producing units. The most important being the Co-generation unit, which produces both heat and electricity. Most plants also have a Heat water storage. Finding the optimal production of both heat and electricity and the optimal use of the storage is a challenging mixed integer nonlinear optimization problem. The calculations may be divided into two sub-problems. The unit commitment problem is the problem to determine when a unit should be producing (on) or not (off). To solve the economic dispatch problem is to find the optimal production plan given which units are producing in each time interval. Together the solution of these two problems form the solution of the short-term production-planning problem. In this thesis a general approach for the mathematical modeling of a co-generation plant is presented. The model objective function is nonlinear, with nonlinear constraints. Internal plant temperatures, mass flows, storage losses, minimal up and down times and time dependent start-up costs are considered. The demand for heat, the forward temperature from the plant, the return temperature to the plant and the price of electricity are assumed to be known quantities. The net electric power produced is sold for the estimated current market price of electricity. The unit commitment problem is solved with an algorithm based on Lagrangian relaxation. The dual search direction is computed by the sub gradient method and the step length by the Polyak rule II. A heuristic method for the generation of primal feasible solutions is developed. The economic dispatch problem is solved using a combination of dynamic programming and general-purpose solvers. Algorithms to find starting values for the problem are developed. The model and the algorithms are implemented in MATLAB, illustrated with numerical examples and analyzed with numerical tests

  16. Cogeneration based on gasified biomass - a comparison of concepts

    Energy Technology Data Exchange (ETDEWEB)

    Olsson, Fredrik

    1999-01-01

    In this report, integration of drying and gasification of biomass into cogeneration power plants, comprising gas turbines, is investigated. The thermodynamic cycles considered are the combined cycle and the humid air turbine cycle. These are combined with either pressurised or near atmospheric gasification, and steam or exhaust gas dryer, in a number of combinations. An effort is made to facilitate a comparison of the different concepts by using, and presenting, similar assumptions and input data for all studied systems. The resulting systems are modelled using the software package ASPEN PLUS{sup TM}, and for each system both the electrical efficiency and the fuel utilisation are calculated. The investigation of integrated gasification combined cycles (IGCC), reveals that systems with pressurised gasification have a potential for electrical efficiencies approaching 45% (LHV). That is 4 - 5 percentage points higher than the corresponding systems with near atmospheric gasification. The type of dryer in the system mainly influences the fuel utilisation, with an advantage of approximately 8 percentage points (LHV) for the steam dryer. The resulting values of fuel utilisation for the IGCC systems are in the range of 78 - 94% (LHV). The results for the integrated gasification humid air turbine systems (IGHAT) indicate that electrical efficiencies close to the IGCC are achievable, provided combustion of the fuel gas in highly humidified air is feasible. Reaching a high fuel utilisation is more difficult for this concept, unless the temperature levels in the district heating network are low. For comparison a conventional cogeneration plant, based on a CFB boiler and a steam turbine (Rankine cycle), is also modelled in ASPEN PLUS{sup TM}. The IGCC and IGHAT show electrical efficiencies in the range of 37 - 45% (LHV), compared with a calculated value of 31% (LHV) for the Rankine cycle cogeneration plant. Apart from the electrical efficiency, also a high value of fuel

  17. Cogenerating fluency in urban science classrooms

    Science.gov (United States)

    Lavan, Sarah-Kate

    This critical ethnographic study employed the use of cogenerative dialogue (Roth & Tobin, 2002) as a means to allow participants of a science classroom to reflect on and transform classroom structures while at the same time create opportunities for all stakeholders to develop collective responsibility for teaching and learning. The research was situated in a science classroom in an inner city charter high school that was both a challenging place for the teacher (Jen Beers) and an oppressive place for the students as all struggled to reconcile issues related to power hierarchies and significant differences in social and cultural histories. As a result, cultural misinterpretations and the undervaluing of students' cultural capital served as a foundation for learning. This study examined the various fields and forms of practice that created opportunities for refining teaching practices and at the same time afforded the development of collective responsibility by addressing the roles, identities and agency of all classroom participants. Specifically, I asked the following questions: (1) How can co-generative dialogue can be used to involve all classroom participants in creating a learning community? (2) How does this shape the identities and roles of the participants who were involved? and (3) How do the changed roles and practices lead toward science fluency? The framework of cultural sociology, specifically the dialectical relationship of structure and agency, interaction ritual theory (Collins, 2003) and research on dispositions (Boykin, 1986), provided analytic tools to investigate the practices of the various stakeholders and the classroom structures as well as the historical and cultural contexts surrounding them. Multiple data resources such as field notes, videotape, interviews and artifacts were drawn on from two fields (the science classroom and cogenerative dialogues) to elicit and support findings at micro, meso and macroscopic levels. The major findings of

    The coupling of heat and power production is particularly interesting in urban areas where these energies present several common factors: an equivalent seasonal variation, with a winter demand largely superior to the summer demand, and a highly concentrated localization in dense urban zones, therefore inducing a minimization of network losses and transport infrastructure requirements, with the advantages of energy savings and pollution reductions. The 1995 situation of cogeneration in France is examined and its potential development is discussed, depending on legal, economical and political conditions. A 1000 MW capacity potential could be reached

    The production of energy in large quantity and at competitive prices is crucial for economic development, which allied to the environmental question, has incentivated the use of renewable sources of energy. One of the most promising sources of renewable energy is the cogeneration from the residues of cane. Currently, the scenario for this kind of energy production is not consolidated, as production prices are not stable, inducing a risky situation for the environment. This work was aimed to study the economic viability of installing a main site for cogeneration of electricity, in a regional sugarcane factory located in the central region of Sao Paulo state that currently uses residues of sugar cane as fuel. The risk factor that was taken into consideration was the price paid for the MWh sold to the Chamber of Commerce of Electricity. The Monte Carlo Method was used to assess the risk factors for the analysis, by using of New Present Value (NPV), in a scenario that uses 20% of the initial investment made by the energy dealer. After the simulations were finished, considering the conditions used in this work, the project tends to be not feasible, as the behavior of the prices of cogenerated MWh are not sufficient for paying the initial investment and the operational costs.

    Japan Atomic Energy Agency began design and development of the Gas Turbine High Temperature Reactor of 300MWe nominal output (GTHTR300) in 2001. The reactor baseline design completed three years later was based on 850 °C core outlet temperature and a direct cycle gas turbine balance of plant. It attained 45.6% net power generation efficiency and 3.5 US¢/kW h cost of electricity. The cost was estimated 20% lower than LWR. The latest design upgrade has incorporated several major technological advances made in the past ten years to both reactor and balance of plant. As described in this paper, these advances have enabled raising the design basis reactor core outlet temperature to 950 °C and increasing power generating efficiency by nearly 5% point. Further implementation of seawater desalination cogeneration is made through employing a newly-proposed multi-stage flash process. Through efficient waste heat recovery of the reactor gas turbine power conversion cycle, a large cost credit is obtained against the conventionally produced water prices. Together, the design upgrade and the cogeneration are shown to reduce the GTHTR300 cost of electricity to under 2.7 US¢/kW h.

  3. A 1000-cell SOFC reactor for domestic cogeneration

    Alston, T.; Kendall, K.; Palin, M.; Prica, M.; Windibank, P.

    A cogeneration system was built using 1000 cells with the intention of supplying 30 kW of hot water and 500 W of power. The basis of the cogenerator was the small tubular SOFC design. 8Y zirconia was mixed into a plastic paste and extruded to form thin-walled tubes. The process produced a zirconia material with high strength and good electrical properties. After drying and firing to full density, electrodes were coated onto the inner and outer surfaces of the electrolyte, then sintered. Current collecting wires were wound around the tubular cells and the tubes were assembled into a reactor. Either hydrogen or a premix of natural gas and air was fed through the tubes and ignited by a hot wire. The ignition shock did not damage the cells in any way. Cycling was achieved within minutes. A steel heat exchanger/recuperator was used to feed hot air to the cell stack. The electrical output was measured via a potentiostat.

  4. The performance of residential micro-cogeneration coupled with thermal and electrical storage

    Science.gov (United States)

    Kopf, John

    Over 80% of residential secondary energy consumption in Canada and Ontario is used for space and water heating. The peak electricity demands resulting from residential energy consumption increase the reliance on fossil-fuel generation stations. Distributed energy resources can help to decrease the reliance on central generation stations. Presently, distributed energy resources such as solar photovoltaic, wind and bio-mass generation are subsidized in Ontario. Micro-cogeneration is an emerging technology that can be implemented as a distributed energy resource within residential or commercial buildings. Micro-cogeneration has the potential to reduce a building's energy consumption by simultaneously generating thermal and electrical power on-site. The coupling of a micro-cogeneration device with electrical storage can improve the system's ability to reduce peak electricity demands. The performance potential of micro-cogeneration devices has yet to be fully realized. This research addresses the performance of a residential micro-cogeneration device and it's ability to meet peak occupant electrical loads when coupled with electrical storage. An integrated building energy model was developed of a residential micro-cogeneration system: the house, the micro-cogeneration device, all balance of plant and space heating components, a thermal storage device, an electrical storage device, as well as the occupant electrical and hot water demands. This model simulated the performance of a micro-cogeneration device coupled to an electrical storage system within a Canadian household. A customized controller was created in ESP-r to examine the impact of various system control strategies. The economic performance of the system was assessed from the perspective of a local energy distribution company and an end-user under hypothetical electricity export purchase price scenarios. It was found that with certain control strategies the micro-cogeneration system was able to improve the

    In this paper we develop an economic model that explains the decision-making problem under uncertainty of an industrial firm that wants to invest in a process technology. More specifically, the decision is between making an irreversible investment in a combined heat-and-power production (cogeneration) system, or to invest in a conventional heat-only generation system (steam boiler) and to purchase all electricity from the grid. In our model we include the main economic and technical variables of the investment decision process. We also account for the risk and uncertainty inherent in volatile energy prices that can greatly affect the valuation of the investment project. The dynamic stochastic model presented allows us to simultaneously determine the optimal technology choice and investment timing. We apply the theoretical model and illustrate our main findings with a numerical example that is based on realistic cost values for industrial oil- or gas-fired cogeneration and heat-only generation in Switzerland. We also briefly discuss expected effects of a CO{sub 2} tax on the investment decision.

    In the cogeneration technology alternatives study (CTAS) a number of advanced coal fired systems were examined and systems using a integrated coal gasifier IGCC or a fluid bed combustor AFB were found to yield attractive cogeneration results in industrial cogeneration applications. A range of site requirements and cogeneration sizing strategies using ground rules based on CTAS were used in comparing an IGCC and an AFB. The effect of time variations in site requirements and the sensitivity to fuel and electricity price assumptions are examined. The economic alternatives of industrial or utility ownership are also considered. The results indicate that the IGCC system has potentially higher fuel and emission savings and could be an attractive option for utility ownership. The AFB steam turbine system has a potentially higher return on investment and could be attractive assuming industrial ownership.

    Industrial Co-Generation has not only an adverse impact on electric utility earnings, but also a positive impact, in that it permits a reduction in capital expenditures related to construction of new generation plants as a means of meeting future load growth. A utility can benefit economically by persuading companies considering industrial co-generation to use their generators for peak load shaving only. This would reduce their maximum demand cost, and also allows the utility to normalize its maximum system demand.

    Advances in coal-fueled gas turbine technology over the past few years, together with recent DOE-METC sponsored studies, have served to provide new optimism that the problems demonstrated in the past can be economically resolved and that the coal-fueled gas turbine can ultimately be the preferred system in appropriate market application sectors. The objective of the Solar/METC program is to prove the technical, economic, and environmental feasibility of a coal-fired gas turbine for cogeneration applications through tests of a Centaur Type H engine system operated on coal fuel throughout the engine design operating range. The five-year program consists of three phases, namely: (1) system description; (2) component development; (3) prototype system verification. A successful conclusion to the program will initiate a continuation of the commercialization plan through extended field demonstration runs.

    The paper describes a software system to simulate the performance of the Carson Ice Co-gen Facility operated by the Carson Energy Group. This 100 MW plant consists of a cogeneration combined cycle and a simple cycle unit powered by LM6000 gas turbine generators. Features of the system include inlet heating/absorption chilling for the gas turbines, supplementary firing capability, and a broad range of steam turbine extractions and admissions. The software enables the operator to model complex operating scenarios. It predicts technical and economic performance under a wide range of conditions, taking into account various equipment constraints and operation preferences. For any set of user-specified operating inputs, the corresponding heat and mass balance diagrams as well as economic figures may be viewed virtually instantaneously. Interactive plots of plant heat rate, incremental heat rate, operating income, and other parameters reveal issues and trade-offs involved in performance and economic optimization.

    Facing the problem of the climatic change and the increase of the fossil energies prices, the government policy of the cogeneration development follows many objectives. Among these objectives it is necessary of implement a new tariff of obligation to buy of the electricity from cogeneration and allow the existing installations to reaffirm their obligation to buy contract. The first part of this report defines the necessary conditions to better use the ecological and economical interest of the natural gas cogeneration and shows that these conditions are not favorable in France. The second part preconizes to modify the actual tariff device in order to maintain the existing park to 2015 in acceptable economical and ecological conditions. (A.L.B.)

  3. Cogeneration and the regulatory framework of energy law; Kraft-Waerme-Kopplung und der energiewirtschaftliche Ordnungsrahmen

    Energy Technology Data Exchange (ETDEWEB)

    Cornehl, Angelika Bettina

    2009-06-15

    The present publication shows that the existing regulatory framework poses numerous impediments to cogeneration plants. This holds especially for industrial operators, but also for municipalities. It has prevented cogeneration from developing its full potential both as an element of competition and as a relief for the environment. Unlike industrial cogeneration plants, those serving the public energy supply at least enjoy the privilege of regional monopoly rights. In today's liberalised electricity market, however, this can be a burden for existing municipal plants which were installed under territorial protection and in many cases have incurred high cost levels and become inflexible and lacking in entrepreneurial spirit as a result. On account of its tendency to promote optimal resource input and efficiency, competition promises positive impulses for the use of cogeneration in small-scale heat grids, where high fuel efficiency matters more. A reform of the competition regime in the power economy would eliminate numerous impediments, particularly for industrial cogeneration operators. Good hopes for the future of cogeneration in a liberalised electricity and gas market are also nurtured by cooperative supply concepts and, within the large domain of services, opportunities held out by special contracting offers.

  4. Evaluating Interventions in the U.S. Electricity System: Assessments of Energy Efficiency, Renewable Energy, and Small-Scale Cogeneration

    Science.gov (United States)

    Siler-Evans, Kyle

    to evaluate the effects of an additional wind turbine or solar panel in the U.S. electricity system. I find that the most attractive sites for renewables depend strongly on one's objective. A solar panel in Iowa displaces 20% more CO2 emissions than a panel in Arizona, though energy production from the Iowa panel is 25% less. Similarly, despite a modest wind resource, a wind turbine in West Virginia is expected to displace 7 times more health and environmental damages than a wind turbine in Oklahoma. Finally, I shift focus and explore the economics of small-scale cogeneration, which has long been recognized as a more efficient alternative to central-station power. Although the benefits of distributed cogeneration are widely cited, adoption has been slow in the U.S. Adoption could be encouraged by making cogeneration more economically attractive, either by increasing the expected returns or decreasing the risks of such investments. I present a case study of a 300-kilowatt cogeneration unit and evaluate the expected returns from: demand response, capacity markets, regulation markets, accelerated depreciation, a price on CO2 emissions, and net metering. In addition, I explore the effectiveness of feed-in tariffs at mitigating the energy-price risks to cogeneration projects.

    The Atmospheric Fluidized-Bed Cogeneration Air Heater Experiment (ACAHE) sponsored by the US Department of Energy (DOE) was initiated to assess the performance of various heat-exchanger materials to be used in fluidized-bed combustion air heater systems. Westinghouse Electric Corporation, through subcontracts with Babcock Wilcox, Foster Wheeler, and ABB Combustion Engineering Systems, prepared specifications and hardware for the ACAHE tests. Argonne National Laboratory contracted with Rockwell International to conduct tests in the DOE atmospheric fluidized-bed combustion facility. This report presents an overview of the project, a description of the facility and the test hardware, the test operating conditions, a summary of the operation, and the results of analyzing specimens from several uncooled and cooled probes exposed in the facility. Extensive microstructural analyses of the base alloys, claddings, coatings, and weldments were performed on specimens exposed in several probes for different lengths of time. Alloy penetration data were determined for several of the materials as a function of specimen orientation and the exposure location in the combustor. Finally, the data were compared with earlier laboratory test data, and the long-term performance of candidate materials for air-heater applications was assessed.

Department of Energy (DOE), National Energy Technology Laboratory (NETL) to assess the technoeconomic viability of building an Early Entrance Co-Production Plant (EECP) in the United States to produce ultra clean Fischer-Tropsch (FT) transportation fuels with either power or steam as the major co-product. The EECP design includes recovery and gasification of low-cost coal waste (culm) from physical coal cleaning operations and will assess blends of the culm with coal or petroleum coke. The project has three phases. Phase I is the concept definition and engineering feasibility study to identify areas of technical, environmental and financial risk. Phase II is an experimental testing program designed to validate the coal waste mixture gasification performance. Phase III updates the original EECP design based on results from Phase II, to prepare a preliminary engineering design package and financial plan for obtaining private funding to build a 5,000 barrel per day (BPD) coal gasification/liquefaction plant next to an existing co-generation plant in Gilberton, Schuylkill County, Pennsylvania.

    1982-01-01

    An advanced state-of-the-art steam turbine-generator developed to serve as the power conversion subsystem for the Department of Energy's Sandia National Laboratories' Solar Total-Energy Project (STEP) is described. The turbine-generator, which is designed to provide 400-kW of net electrical power, represents the largest turbine-generator built specifically for commercial solar-powered cogeneration. The controls for the turbine-generator incorporate a multiple, partial-arc entry to provide efficient off-design performance, as well as an extraction control scheme to permit extraction flow regulation while maintaining 110-spsig pressure. Normal turbine operation is achieved while synchronized to a local utility and in a stand-alone mode. In both cases, the turbine-generator features automatic load control as well as remote start-up and shutdown capability. Tests totaling 200 hours were conducted to confirm the integrity of the turbine's mechanical structure and control function. Performance tests resulted in a measured inlet throttle flow of 8,450 pounds per hour, which was near design conditions.

    The only residual-oil-fired low speed diesel cogeneration facility in the US has been in operation for a year at the Hoffman-LaRoche Vitamin C plant in Belvidere, NJ. Operating data for this grid-connected 23 MW facility are used to construct a generic evaluation of the economic desirability of such systems for industrial electric/thermal applications and industrial-thermal/commercial-electrical applications made possible by recent US legislation (PURPA). The post 1980 changes in relative electrical and residual oil prices are shown to have made oil fired on-site generation more attractive. The likely 1985-2005 movements of electricity and residual oil prices are discussed, along with risks of error in projections. The system is evaluated as a whole and on an incremental basis. Incremental analysis includes (1) the economics of steam and hot water use given the diesel and (2) the economics of system generation given industrial electric, steam and hot water loads. The sensitivity of the economics of the system to the full range of US electricity and residual oil prices is estimated. The effect of variation in system loads is examined. The economic desirability of the system is often great but is also highly variable geographically, largely as a function of local evaded electricity charges.

    This paper provides a detailed case study on Austria's by far largest biomass cogeneration plant. The plant is located in the city of Vienna and scheduled to be put into operation by mid-2006. Given the urban location of the plant and its significant biomass fuel input requirements, fuel delivery logistics play an important role-not only from an economic point of view, but also in relation to supply security and environmental impact. We describe and analyse the history of the project, putting particular emphasis on the main driving forces and actors behind the entire project development process. From this analysis we deduce the following main socio-economic drivers and success factors for the realisation of large bioenergy projects in urban settings: (1) a critical mass of actors; (2) a priori political consensus; (3) the existence of a problem (and problem awareness) that calls for decisive steps to be taken; (4) institutional innovation and changes in the mindset of the main decision makers; (5) favourable economic conditions; (6) change agents that are actively engaged from an early stage of development; (7) intra-firm supporters at different hierarchical levels and from different departments; and (8) targeted study tours that help to reduce uncertainty, to enable leapfrogging in project planning and design, and to build up confidence in the project's feasibility and chance of success.

  19. Feasibility of a medium-size central cogenerated energy facility, energy management memorandum

    Science.gov (United States)

    Porter, R. W.

    1982-09-01

    The thermal-economic feasibility was studied of a medium-size central cogenerated energy facility designed to serve five varied industries. Generation options included one dual-fuel diesel and one gas turbine, both with waste heat boilers, and five fired boilers. Fuels included natural gas, and for the fired-boiler cases, also low-sulphur coal and municipal refuse. The fired-boiler cogeneration systems employed back-pressure steam turbines. For coal and refuse, the option of steam only without cogeneration was also assessed. The refuse-fired cases utilized modular incinerators. The options provided for a wide range of steam and electrical capacities. Deficient steam was assumed generated independently in existing equipment. Excess electrical power over that which could be displaced was assumed sold to Commonwealth Edison Company under PURPA (Public Utility Regulator Policies Act). The facility was assumed operated by a mutually owned corporation formed by the cogenerated power users. The economic analysis was predicted on currently applicable energy-investment tax credits and accelerated depreciation for a January 1985 startup date. Based on 100% equity financing, the results indicated that the best alternative was the modular-incinerator cogeneration system.

  20. Co-Generation and Renewables: Solutions for a Low-Carbon Energy Future

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2011-07-01

    Co-generation and renewables: solutions for a low-carbon energy future shows that powerful synergies exist when co-generation and renewables work together. The report documents, for the first time, some of the little-known complementary aspects of the two technologies. It also re-emphasises the stand-alone benefits of each technology. Thus, decision makers can use the report as a 'one-stop shop' when they need credible information on co-generation, renewables and the possible synergies between the two. It also provides answers to policy makers' questions about the potential energy and environmental benefits of an increased policy commitment to both co-generation and renewables. Secure, reliable, affordable and clean energy supplies are fundamental to economic and social stability and development. Energy and environmental decision-makers are faced with major challenges that require action now in order to ensure a more sustainable future. More efficient use of, and cleaner primary energy sources can help to achieve this goal. Co-generation -- also known as combined heat and power (CHP) -- represents a proven, cost-effective and energy-efficient solution for delivering electricity and heat. Renewable sources provide clean and secure fuels for producing electricity and heat.

  1. Avoided costs associated with cogeneration: a case study of Con Ed

    Energy Technology Data Exchange (ETDEWEB)

    Bright, R.; Davitian, H.; Martorella, J.

    1980-08-01

    The potential impact of cogeneration in office and apartment buildings in New York City on the Consolidated Edison Company (Con Ed) has been investigated using a method of utility cost and fuel use analysis developed at Brookhaven National Laboratory. This method computes a utility's long run marginal costs and long run marginal fuel consumption associated with load modifications due to the introduction of on-site energy producing technologies. The principal findings of this study show that Con Ed's long run average cost is more likely to go down than up due to cogeneration in office and apartment building; the utility's avoided costs (i.e., its long run marginal savings) associated with the gross power output of the cogeneration systems are 10.5 cents/KWh for the office building and 6.4 cents/KWh for the apartment buildings; the utility's marginal savings include a component for avoided capacity costs; and there are net savings in the use of oil due to cogeneration (assuming the building used oil for its boilers before it switched and diesel fuel in its cogenerators afterwards).

  2. Efficiency Assessment of Support Mechanisms for Wood-Fired Cogeneration Development in Estonia

    Volkova, Anna; Siirde, Andres

    2010-01-01

    There are various support mechanisms for wood-fired cogeneration plants, which include both support for cogeneration development and stimulation for increasing consumption of renewable energy sources. The efficiency of these mechanisms is analysed in the paper. Overview of cogeneration development in Estonia is given with the focus on wood-fired cogeneration. Legislation acts and amendments, related to cogeneration support schemes, were described. For evaluating the efficiency of support mechanisms an indicator - fuel cost factor was defined. This indicator includes the costs related to the chosen fuel influence on the final electricity generation costs without any support mechanisms. The wood fuel cost factors were compared with the fuel cost factors for peat and oil shale. For calculating the fuel cost factors, various data sources were used. The fuel prices data were based on the average cost of fuels in Estonia for the period from 2000 till 2008. The data about operating and maintenance costs, related to the fuel type in the case of comparing wood fuel and oil shale fuel were taken from the CHP Balti and Eesti reports. The data about operating and maintenance costs used for peat and wood fuel comparison were taken from the Tallinn Elektrijaam reports. As a result, the diagrams were built for comparing wood and its competitive fuels. The decision boundary lines were constructed on the diagram for the situation, when no support was provided for wood fuels and for the situations, when various support mechanisms were provided during the last 12 years.

    Waste Processors Management, Inc. (WMPI), along with its subcontractors Texaco Power & Gasification (now ChevronTexaco), SASOL Technology Ltd., and Nexant Inc. entered into a Cooperative Agreement DE-FC26-00NT40693 with the U. S. Department of Energy (DOE), National Energy Technology Laboratory (NETL) to assess the techno-economic viability of building an Early Entrance Co-Production Plant (EECP) in the United States to produce ultra clean Fischer-Tropsch (FT) transportation fuels with either power or steam as the major co-product. The EECP design includes recovery and gasification of low-cost coal waste (culm) from physical coal cleaning operations and will assess blends of the culm with coal or petroleum coke. The project has three phases. Phase I is the concept definition and engineering feasibility study to identify areas of technical, environmental and financial risk. Phase II is an experimental testing program designed to validate the coal waste mixture gasification performance. Phase III updates the original EECP design based on results from Phase II, to prepare a preliminary engineering design package and financial plan for obtaining private funding to build a 5,000 barrel per day (BPD) coal gasification/liquefaction plant next to an existing co-generation plant in Gilberton, Schuylkill County, Pennsylvania. The current report covers the period performance from July 1, 2003 through September 30, 2003. The DOE/WMPI Cooperative Agreement was modified on May 2003 to expand the project team to include Shell Global Solutions, U.S. and Uhde GmbH as the engineering contractor. The addition of Shell and Uhde strengthen both the technical capability and financing ability of the project. Uhde, as the prime EPC contractor, has the responsibility to develop a LSTK (lump sum turnkey) engineering design package for the EECP leading to the eventual detailed engineering, construction and operation of the proposed concept.

    The environmental and energetic effects of cogeneration are often compared with large-scale power generation by fossil-fuel power plants. However, this is based on technology of 1990. The method to calculate the reduction of CO2 emission, realized by cogeneration, and the interpretation of the results, are evaluated.

  7. Energy balance model of a SOFC cogenerator operated with biogas

    Van herle, Jan; Maréchal, F.; Leuenberger, S.; Favrat, D.

    A small cogeneration system based on a Solid Oxide Fuel Cell (SOFC) fed on the renewable energy source biogas is presented. An existing farm biogas production site (35 m 3 per day), currently equipped with a SOFC demonstration stack, is taken for reference. A process flow diagram was defined in a software package allowing to vary system operating parameters like the fuel inlet composition, reforming technology, stack temperature and stack current (or fuel conversion). For system reforming simplicity, a base case parameter set was defined as the fuel inlet of 60% CH 4:40% CO 2 mixed with air in a 1:1 ratio, together with 800 °C operating temperature and 80% fuel conversion. A model stack, consisting of 100 series elements of anode supported electrolyte cells of 100 cm 2 each, was calculated to deliver 3.1 kW el and 5.16 kW th from an input of 1.5 N m 3/h of biogas (8.95 kW LHV), corresponding to 33.8 and 57.6% electrical and thermal efficiencies (Lower Heating Values (LHVs)), respectively. The incidence on the efficiencies of the model system was examined by the variation of a number of parameters such as the CO 2 content in the biogas, the amount of air addition to the biogas stream, the addition of steam to the fuel inlet, the air excess ratio λ and the stack operating temperature, and the results discussed.

    1980-01-01

    Cogenerating electric power and process heat in single energy conversion systems rather than separately in utility plants and in process boilers is examined in terms of cost savings. The use of various advanced energy conversion systems are examined and compared with each other and with current technology systems for their savings in fuel energy, costs, and emissions in individual plants and on a national level. About fifty industrial processes from the target energy consuming sectors were used as a basis for matching a similar number of energy conversion systems that are considered as candidate which can be made available by the 1985 to 2000 time period. The sectors considered included food, textiles, lumber, paper, chemicals, petroleum, glass, and primary metals. The energy conversion systems included steam and gas turbines, diesels, thermionics, stirling, closed cycle and steam injected gas turbines, and fuel cells. Fuels considered were coal, both coal and petroleum based residual and distillate liquid fuels, and low Btu gas obtained through the on site gasification of coal. An attempt was made to use consistent assumptions and a consistent set of ground rules specified by NASA for determining performance and cost. Data and narrative descriptions of the industrial processes are given.

  9. Public radiation exposures from a CANDESAL Co-generation Facility

    Khaloo, R. [Atomic Energy of Canada Limited, Mississauga, ON (Canada); Simanjuntak, A. [PRSG-BATAN, Tangerang (Indonesia)

    1998-07-01

    As part of an evaluation of the practical and economic viability of using the CANDESAL (CANDU DESALINATION) approach to desalinate water in an Indonesian environment, radiation doses to members of the public were conservatively calculated. The calculations show there is a negligible radiological impact on the public. Conservative radiation doses to members of the critical group (an adult male and a 1-year-old infant) were calculated, according to the CAN/CSA N288.1-M87 compartmental pathways analysis methodology, and show that use of the desalinated water supply would increase the dose to a member of the critical group (adult or infant) by less than 20 {mu}Sv{center_dot}a{sup -1}. About 99% of the dose from the CANDESAL facility is from tritiated heavy water (DTO or HTO) and the rest is from trace concentrations of beta and gamma emitters. The doses to a member of the critical group from a combined CANDU 6 and CANDESAL Co-generation Facility will be less than 4% of the ICRP-60 recommended effective dose limit of 1000 {mu}Sv{center_dot}a{sup -1} to a member of the public. These doses are not only a small fraction of the regulatory dose limits, but are also within the normal variations of natural background radiation levels. (author)

  10. Biogas as a fuel source for SOFC co-generators

    Science.gov (United States)

    Van herle, Jan; Membrez, Yves; Bucheli, Olivier

    This study reports on the combination of solid oxide fuel cell (SOFC) generators fueled with biogas as renewable energy source, recoverable from wastes but at present underexploited. From a mobilisable near-future potential in the European Union (EU-15) of 17 million tonnes oil equivalent (Mtoe), under 15% appears to be converted today into useful heat and power (2 Mtoe). SOFCs could improve and promote the exploitation of biogas on manifold generation sites as small combined heat and power (5-50 kW el), especially for farm and sewage installations, raising the electrical conversion efficiency on such reduced and variable power level. Larger module packs of the high temperature ceramic converter would also be capable of operating on contaminated fuel of low heating value (less than 40% that of natural gas) which can emanate from landfill sites (MW-size). Landfill gas delivers 80% of current world biogas production. This document compiles and estimates biogas data on actual production and future potential and presents the thermodynamics of the biogas reforming and electrochemical conversion processes. A case study is reported of the energy balance of a small SOFC co-generator operated with agricultural biogas, the largest potential source.

  11. Supercritical biodiesel production and power cogeneration: technical and economic feasibilities.

    Science.gov (United States)

    Deshpande, A; Anitescu, G; Rice, P A; Tavlarides, L L

    2010-03-01

    An integrated supercritical fluid technology with power cogeneration to produce biodiesel fuels, with no need for the costly separations involved with the conventional technology, is proposed, documented for technical and economic feasibility, and preliminarily designed. The core of the integrated system consists of the transesterification of various triglyceride sources (e.g., vegetable oils and animal fats) with supercritical methanol/ethanol. Part of the reaction products can be combusted by a diesel power generator integrated in the system which, in turn, provides the power needed to pressurize the system and the heat of the exhaust gases necessary in the transesterification step. The latter energy demand can also be satisfied by a fired heater, especially for higher plant capacities. Different versions of this system can be implemented based on the main target of the technology: biodiesel production or diesel engine applications, including power generation. The process options considered for biodiesel fuel production estimate break-even processing costs of biodiesel as low as $0.26/gal ($0.07/L) with a diesel power generator and $0.35/gal ($0.09/L) with a fired heater for a plant capacity of 15,000 gal/day (56,775 L/day). Both are significantly lower than the current processing costs of approximately $0.51/gal ($0.13/L) of biodiesel produced by conventional catalytic methods. A retail cost of biodiesel produced by the proposed method is likely to be competitive with the prices of diesel fuels.

    Sagerman, G. D.; Barna, G. J.; Burns, R. K.

    1979-01-01

    An overview of the organization and methodology of the Cogeneration Technology Alternatives Study is presented. The objectives of the study were to identify the most attractive advanced energy conversion systems for industrial cogeneration applications in the future and to assess the advantages of advanced technology systems compared to those systems commercially available today. Advanced systems studied include steam turbines, open and closed cycle gas turbines, combined cycles, diesel engines, Stirling engines, phosphoric acid and molten carbonate fuel cells and thermionics. Steam turbines, open cycle gas turbines, combined cycles, and diesel engines were also analyzed in versions typical of today's commercially available technology to provide a base against which to measure the advanced systems. Cogeneration applications in the major energy consuming manufacturing industries were considered. Results of the study in terms of plant level energy savings, annual energy cost savings and economic attractiveness are presented for the various energy conversion systems considered.

    Directory of Open Access Journals (Sweden)

    P. Asiedu-Boateng

    2012-04-01

    Full Text Available Nuclear desalination of seawater has been identified as one of the affordable means of fresh water production. However this can only be achieved by the design of energy efficient desalination systems. This study focused on cycle analysis of the cogeneration nuclear power plant. A theoretical model of the Thermo Vapour Compression (TVC desalination process was also developed and coupled to the cogeneration nuclear power plant. The modeled coupled system was developed on the computer code, NUCDES using FORTRAN language to investigate the effect of design and operating parameters on parameters controlling the cost of producing fresh water from TVC process. The results showed that the performance of the TVC desalination process and the efficiency of the cogeneration nuclear power improve with the motive steam pressure.

    This special issue focuses on ‘ways of seeing’ the city and raise questions about current dominant epistemological frameworks for understanding the urban-based sociabilities of people whom policy-makers and researchers frequently speak about as foreign, diverse and requiring integration. Read...... together, the articles contribute to an emerging relational social science by approaching urban sociabilities through four interrelated parameters: (1) a concept of place-making situated within trajectories of differential and multiscalar power; (2) a discursive analysis of narratives and silences...... of ‘the social’, so that diversity, variation, mobility and conflict are seen as aspects of all urban social life, and not exclusively an attribute of ‘the other’....

  19. Thermal Efficiency of Cogeneration Units with Multi-Stage Reheating for Russian Municipal Heating Systems

    Directory of Open Access Journals (Sweden)

    Evgeny Lisin

    2016-04-01

    Full Text Available This paper explores the layout of an optimum process for supplying heat to Russian municipal heating systems operating in a market environment. We analyze and compare the standard cogeneration unit design with two-stage reheating of service water coming from controlled extraction locations and layouts that employ three in-line reheaters with heat the supply controlled by a rotary diaphragm and qualitative/quantitative methods (so-called “uncontrolled extraction”. Cogeneration unit designs are benchmarked in terms of their thermal efficiency expressed as a fuel consumption rate. The specific fuel consumption rate on electricity production is viewed as a key parameter of thermal efficiency.

    Developing safe, reliable, cost-effective, and efficient hydrogen-electricity co-generation systems is an important step in the quest for national energy security and minimized reliance on foreign oil. This project aimed to, through materials research, develop a cost-effective advanced technology cogenerating hydrogen and electricity directly from distributed natural gas and/or coal-derived fuels. This advanced technology was built upon a novel hybrid module composed of solid-oxide fuel-assisted electrolysis cells (SOFECs) and solid-oxide fuel cells (SOFCs), both of which were in planar, anode-supported designs. A SOFEC is an electrochemical device, in which an oxidizable fuel and steam are fed to the anode and cathode, respectively. Steam on the cathode is split into oxygen ions that are transported through an oxygen ion-conducting electrolyte (i.e. YSZ) to oxidize the anode fuel. The dissociated hydrogen and residual steam are exhausted from the SOFEC cathode and then separated by condensation of the steam to produce pure hydrogen. The rationale was that in such an approach fuel provides a chemical potential replacing the external power conventionally used to drive electrolysis cells (i.e. solid oxide electrolysis cells). A SOFC is similar to the SOFEC by replacing cathode steam with air for power generation. To fulfill the cogeneration objective, a hybrid module comprising reversible SOFEC stacks and SOFC stacks was designed that planar SOFECs and SOFCs were manifolded in such a way that the anodes of both the SOFCs and the SOFECs were fed the same fuel, (i.e. natural gas or coal-derived fuel). Hydrogen was produced by SOFECs and electricity was generated by SOFCs within the same hybrid system. A stand-alone 5 kW system comprising three SOFEC-SOFC hybrid modules and three dedicated SOFC stacks, balance-of-plant components (including a tailgas-fired steam generator and tailgas-fired process heaters), and electronic controls was designed, though an overall

    Mexico has an industrial cogeneration potential very important, not evaluated or projected within its historical growth. The objective of the present work consist of studying the industrial cogeneration potential that exists in Mexico, as well as the economic and environmental savings that it would be achieved if one took advantage of this potential. As a result of the present work we can conclude that the cogeneration in Mexico offers a theoretical potential middle of 28,000 MWe to the 2007. It is estimated an economic saving potential in the construction of generation infrastructure electrical, for the high stage of its utilization of almost 7000 million dollars and a stage of emissions reduction of 2007- 21.4%, instead of 2007- 0.35%, for the industrial sector of the country. Provided that change the vision of the government of seeing to the cogeneration as a measure of energy saving and substitute it by that of political of complement to the development of the national electrical sector. [Spanish] Mexico tiene un importante potencial de cogeneracion industrial que no ha sido evaluado ni proyectado dentro de su crecimiento historico, por ello, el objetito de este trabajo consiste en estudiar y conocer los ahorros economicos y ambientales que se podrian lograr si se aprovechara dicho potencial. Como resultado, se muestra que la cogeneracion en Mexico ofrece un potencial teorico medio de 28,000 MW e al ano 2007. Se estima tambien un ahorro economico en la construccion de infraestructura de generacion electrica para el escenario alto de su aprovechamiento de casi 7000 mdd, y un escenario de reduccion de emisiones para el sector industrial del pais de un 0.35% a un 21.47% para el ano 2007. Estos pronosticos se pueden lograr, siempre y cunado el gobierno cambie la vision de manejar este tema como una medida de ahorro de energia, y la sustituya por la politica de complemento al desarrollo del sector electrico nacional.

  20. Effectiveness of place-based science curriculum projects situated in Hawaiian and Western cultural institutions at an urban high school in Hawai'i

    Kuwahara, Jennifer Leslie Hoof

    Place-based education is a multidisciplinary and experiential approach to learning that utilizes a local environment or community. This study examined the influences of place attachment and cultural affiliation in the school on student experience and learning in a place-based science course, as well as the course's potential influence on environmentally responsible behaviors. The participants attended an urban high school on O'ahu, Hawai'i. By understanding student reaction to experience in both Western- and Hawaiian-centered classes, this study contributes to the literature on place-based education in relation to how differences in cultural affiliation in a school setting can have varying impacts on place attachment, science literacy, and environmental responsibility. A comparative case study was conducted with students enrolled in the Hawaiian Academy and non-academy students. Analysis of a pre- and post-survey and science content assessments, student documents, field notes, and interview transcripts suggested place-based science has both similar and different impacts on students depending on cultural affiliation within the school. Students in the Hawaiian Academy, as a whole, showed stronger science literacy and environmental responsibility than students in the non-Hawaiian Academy class. However, non-Hawaiian Academy students showed increased place attachment in a spiritual sense. Reactions from both groups suggest a need for smaller learning communities that promote a unity of knowledge rather than distinct courses and disciplines.

    Successful cogeneration system performance depends critically upon the correct estimation of load variation and the accuracy of demand prediction. We need not only aggregated annual heat and electricity demands, but also hourly and monthly patterns in order to evaluate a cogeneration system's performance by computer simulation. These data are usually obtained from the actual measurements of energy demand in existing buildings. However, it is extremely expensive to collect actual energy demand data and store it over a long period for many buildings. However we face the question of whether it is really necessary to survey hourly demands. This paper provides a sensitivity analysis of the influence of demand-prediction error upon the efficiency of cogeneration system, so as to evaluate the relative importance of various demand components. These components are annual energy demand, annual heat-to-electricity ratio, daily load factor and so forth. Our approach employs the concept of information theory to construct a mathematical model. This analysis provides an indication of the relative importances of demand indices, and identifies what may become a good measure of assessing the efficiency of the cogeneration system for planning purposes.

    Full Text Available This paper provides a review of co-generation process in fuel cell type reactor to produce valuable chemical compounds along with electricity. The chemicals and energy co-generation processes have been shown to be a promising alternative to conventional reactors and conventional fuel cells with pure water as a byproduct. This paper reviews researches on chemicals and energy co-generation technologies of three types of promising fuel cell i.e. solid oxide fuel cell (SOFC, alkaline fuel cell (AFC, and proton exchange membrane fuel cell (PEMFC. In addition, the research studies on applications of SOFCs, AFCs, and PEMFCs with chemical production (i.e. nitric oxide, formaldehyde, sulfur oxide, C2 hydrocarbons, alcohols, syngas and hydrogen peroxide were also given. Although, it appears that chemicals and energy co-generation processes have potential to succeed in commercial applications, the development of cheaper catalyst materials with longer stability ,and understanding in thermodynamic are still challenging to improve the overall system performance and enable to use in commercial market.

    Micro-cogeneration offers numerous potential advantages for the supply of energy to residential buildings in the sense of improved energy efficiency and reduced environmental burdens. To realize these benefits, however, such systems must reduce energy costs, primary energy consumption, and CO{sub 2} emissions relative to conventional heating systems. In this paper, we search for optimized strategies for the integration of a Stirling engine-based micro-cogeneration system in residential buildings by comparing the performance of various system configurations and operational strategies with that of a reference system, i.e. hydronic heating and a low temperature gas boiler in standard and passive house constructions located in different climates. The IDA-ICE whole-building simulation program is employed with the Stirling engine micro-cogeneration model that was developed by IEA/ECBCS Annex 42. In this way the dynamic effects of micro-cogeneration devices, such as warm-ups and shutdowns, are accounted for. This study contributes to the research by addressing hourly changes in the fuel mix used for central electricity generation and the utilization of thermal exhaust through heat recovery. Our results suggest that an optimally operated micro-cogeneration system encompassing heat recovery and appropriate thermal storage would result in a 3-5% decrease in primary energy consumption and CO{sub 2} emissions when compared to a conventional hydronic heating system. Moreover, this configuration is capable of delivering annual savings in all the combinations of electricity and fuel price between 0.05 and 0.15 EUR kW h{sup -1}. As can be expected, these results are sensitive to the electrical energy supply mix, building type, and climate. (author)

  18. Influence of biomass cofiring on the optimal coefficient of the cogeneration share in a district heating system

    Directory of Open Access Journals (Sweden)

    Ziębik Andrzej

    2014-03-01

    Full Text Available The paper presents a modified algorithm for choosing the optimal coefficient of the share of cogeneration in district heating systems taking into account additional benefits concerning the promotion of highefficiency cogeneration and biomass cofiring. The optimal coefficient of the share of cogeneration depends first of all on the share of the heat required for preparing the hot tap water. The final result of investigations is an empirical equation describing the influence of the ratio of the heat flux for the production of hot tap water to the maximum flux for space heating and ventilation, as well as the share of chemical energy of biomass in the fuel mixture on the optimal value of the share of cogeneration in district heating systems. The approach presented in the paper may be applied both in back-pressure combined heat and power (CHP plants and in extraction-condensing CHP plants.

    This study aims to examine the technical feasibility and financial cost for a cogeneration system in a company in the tertiary sector. For this, was studied the electromechanical and thermal characteristics of a shopping center, as well as the technologies associated with the proposed cogeneration system. From the modeling of electric and thermal loads it was determined the system of operation for the system and the possible surplus energy generated. For the analysis of economic viability compare operating costs without cogeneration and with the alternative of cogeneration chosen. Among the calculations are the costs of investment and operation of the system. Was encountered the attractiveness of a cogeneration system, which uses natural gas as fuel for alternative engines and, in turn, reject heat to the absorption chillers. The idealized cogeneration system was also evaluated positively with a view to qualification required for participation in policies to encourage the rational use of energy resources. (author)

    2002-07-01

    Waste Processors Management, Inc. (WMPI), along with its subcontractors entered into a Cooperative Agreement with the US Department of Energy (DOE) and the National Energy Technology Laboratory (NETL) to assess the techno-economic viability of building an Early Entrance Co-Production Plant (EECP) in the US to produce ultra clean Fischer-Tropsch (FT) transportation fuels with either power or steam as the major co-product. The EECP design includes recovery and gasification of low-cost coal waste (culm) from physical coal cleaning operations and will assess blends of the culm with coal or petroleum coke. The project has three phases. Phase 1 is the concept definition and engineering feasibility study to identify areas of technical, environmental and financial risk. Phase 2 is an experimental testing program designed to validate the coal waste mixture gasification performance. Phase 3 updates the original EECP design based on results from Phase 2, to prepare a preliminary engineering design package and financial plan for obtaining private funding to build a 5,000 barrel per day (BPD) coal gasification/liquefaction plant next to an existing co-generation plant in Gilberton, Schuylkill County, Pennsylvania. The current report covers the period performance from April 1, 2002 through June 30, 2002.

    Lake sediment cores provide scalable, interdisciplinary research projects that are well suited for summer internships such as the NSF-REU (Research Experience for Undergraduates). Short paleorecords (100-500 years or about a meter of core) are easy to collect and are tractable in terms of sample numbers (Myrbo et al. 2011). Many students find it compelling to reconstruct the recent past; choosing sites with cultural or historical significance is another way to make research seem more relevant. We present the results and experiences of designing two- and ten-week individual, group, and team research projects. Each of these projects contributes to the findings of a collaborative inquiry by the Fond du Lac Band of Lake Superior Chippewa (FDL) and the University of Minnesota (UMN). Research questions are determined and framed by FDL Resource Management, and student projects are supported and advised by both FDL and UMN scientists. The research is focused on the past environmental conditions of on- and off-Reservation wild rice lakes and the surrounding landscapes and people, and includes the study of biological and chemical proxies as well as historical records. Over the past three years, this approach has enabled diverse groups of students to conduct authentic and original basic research that also has applications to management and planning issues for Tribal resource managers, and to develop skills that are portable to other management and academic settings. These compelling "short" time scale projects can serve as a gateway for students to further pursue science including longer term paleorecords, climate change research, other disciplines in ecology, water resources, geography, archeology, and geology, as well as humanities research areas such as history and landscape architecture. An overarching goal is to help students understand current environmental change in the context of long-term changes, pre-industrial human land use, and accelerated Anthropocene impacts

    Full Text Available The paper presents a part of the work conducted in the first stage of a Research Grant called ”Hybrid micro-cogeneration group of high efficiency equipped with an electronically assisted ORC” acronym GRUCOHYB. The hybrid micro-cogeneration group is equipped with a four stroke Diesel engine having a maximum power of 40 kW. A mathematical model of the internal combustion engine is presented. The mathematical model is developed based on the Laws of Thermodynamics and takes into account the real, irreversible processes. Based on the mathematical model a computation program was developed. The results obtained were compared with those provided by the Diesel engine manufacturer. Results show a very high correlation between the manufacturer’s data and the simulation results for an engine running at 100% load. Future developments could involve using an exergetic analysis to show the ability of the ORC to generate electricity from recovered heat

    A thermal and economic study, carried on by using the first and second law of thermodynamics concepts demonstrated the economic feasibility of the cogeneration system, and proposed modifications to be done in the studied cryogenic plant, a typical T-240 NA MPL3 plant. The thermodynamic analysis showed that the second law efficiency of the processes could be improved, together with a 12% electric energy consumption reduction. Four cogeneration schemes were analyzed with both the first and second laws of thermodynamics and, then, the economic analysis was performed. Rankine, Brayton, Otto and Combined gas-steam basic cycles were used in this analysis.The combined gas-steam cycle was shown to be more economically feasible than others. Thermal and electric loads were well balanced, resulting in a higher second law efficiency. Although the initial investment for the modification was higher, the savings resulted to be higher, turning into a higher rate of return of the investment. (author)

    2003-01-01

    Full Text Available Great differences are encountered among Caucasus region countries with respect to energy resources reserves and economic conditions. Thermal power plants consist of obsolete and inefficient units, while the Soviet-type large heating systems in the area collapsed after 1992 and their reconstruction is considered uneconomic. Renovation needs of the power and heat sector, and the potential of Fluidised Bed Combustion implementations in decentralized cogeneration units were investigated, since operating oil and gas power plants exhibit high fuel consumption, low efficiency and poor environmental performance. Results showed significant prospects of Fluidised Bed Combustion utilization in decentralized cogeneration units in the Caucausus region heat and power sector. Their introduction constitutes an economically attractive way to cover power and heat demands and promotes utilization of domestic energy resources in all of three countries, provided that financial difficulties could be confronted.

  12. The Optimization of a Cogeneration System for Commercial Buildings by the Particle Swarm Optimization

    Science.gov (United States)

    Miyazaki, Takahiko; Akisawa, Atsushi; Kashiwagi, Takao

    The cogeneration system provides electricity as well as heating and cooling, which consequently leads to a complexity of the design and operation of the system. It requires, therefore, the optimization of parameters such as the number of machines and the capacity of equipment. Generally, the problem can be expressed as a mixed integer nonlinear programming problem, and a lot of efforts would be required to solve it. In this paper, we present a different approach to the optimization of cogeneration systems, which facilitates to find a quasi-optimum solution. The particle swarm optimization combined with a simulation of the system is applied to the minimization of the primary energy consumption and of the system cost. The results present the optimum system constitutions for medium- and large-sized buildings. The result of the system cost minimization under a constraint of the energy saving rate is also discussed.

  2. Co-generation potentials of municipal solid waste landfills in Serbia

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Waste management in the Republic of Serbia is based on landfilling. As a result of such year-long practice, a huge number of municipal waste landfills has been created where landfill gas has been generated. Landfill gas, which is essentially methane (50-55% and carbon dioxide (40-45% (both GHGs, has a great environmental impact which can be reduced by using landfill gas in cogeneration plants to produce energy. The aim of this paper is to determine economic and environmental benefits from such energy production. For that purpose, the database of cogeneration potentials (CP of 51 landfills in the Republic of Serbia (RS was created. Amount of landfill gas generated at each municipal landfill was calculated by applying a first order decay equation which requires the data about solid waste production and composition and about some landfill characteristics. For all landfills, which have over 100,000 m3 each, a techno-economic analysis about building a CHP plant was conducted. The results have shown, that the total investment in 14 CHP plants with payback period of less than 7 years amounts € 11,721,288. The total nominal power of these plants is 7 MW of electrical power and 7.9 MW of thermal power, and an average payback period is about 61 months. In addition, using landfill biogas as energy source in proposed plants would reduce methane emission for 161,000 tons of CO2 equivalent per year. [Projekat Ministarstva nauke Republike Srbije, br.

    In the year 2003, a new gas province will come on stream when gas production commences from the fields of In Salah Gas Project in southern Algerian. The In Salah Gas Project is a partnership between Sonatrach and BP Amoco involving joint activities in a fully integrated upstream and downstream gas business including exploration, appraisal, development, transportation and gas marketing. Joint Sonatrach and BP Amoco activities to prepare the Development Plan were undertaken by the Organe des Operations Conjointes (OOC) based in Hassi Messaoud and London. Joint Sonatrach and BP Amoco activities to market the gas sales into southern Europe were undertaken by the joint marketing company (In Salah Gas) based in the Hague, Netherlands. The OOC submitted a Development Plan in November 1999 to meet the In Salah Gas marketing expectations for gas sales contracts to deliver a total of 911 bcm per year to customers in southern Europe. The major challenge has been to demonstrate to the shareholders Sonatrach and BP Amoco a high level of assurance in ability to deliver the In Salah Gas Project and fully meet the commitments to HSE, quality, planning budget and Algerian content.

  6. Error and Complexity Analysis for a Collocation-Grid-Projection Plus Precorrected-FFT Algorithm for Solving Potential Integral Equations with LaPlace or Helmholtz Kernels

    Phillips, J. R.

    1996-01-01

    In this paper we derive error bounds for a collocation-grid-projection scheme tuned for use in multilevel methods for solving boundary-element discretizations of potential integral equations. The grid-projection scheme is then combined with a precorrected FFT style multilevel method for solving potential integral equations with 1/r and e(sup ikr)/r kernels. A complexity analysis of this combined method is given to show that for homogeneous problems, the method is order n natural log n nearly independent of the kernel. In addition, it is shown analytically and experimentally that for an inhomogeneity generated by a very finely discretized surface, the combined method slows to order n(sup 4/3). Finally, examples are given to show that the collocation-based grid-projection plus precorrected-FFT scheme is competitive with fast-multipole algorithms when considering realistic problems and 1/r kernels, but can be used over a range of spatial frequencies with only a small performance penalty.

    Using thermoeconomics as a tool to identify the location and magnitude of the real thermodynamic losses (energy waste, or exergy destruction and exergy losses) it is possible to assess the production costs of each product (electric power and heat) and the exergetic and exergoeconomic cost of each flow in a cogeneration plant to assist in decision-marketing procedures concerning to plant design, investment, operation and allocations of research funds. Thermo economic analysis of Biomass Integrated Gasification Gas Turbine Combined Cycle (BIG GT CC) cogeneration plant for its applications in sugar cane mills brings the following results: the global exergetic efficiency is low; the highest irreversibilities occur in the following equipment, by order: scrubber (38%), gas turbine (16%), dryer (12%), gasifier and HRSG (6%); due to the adopted cost distribution methodology, the unit exergetic cost of the heat (4,11) is lower than electricity (4,71); the lower market price of biomass is one of the most sensible parameter in the possible implementation of BIG-GT technology in sugar cane industry; the production costs are 31 US$/MWh and 32 US$/MWh for electricity and heat, respectively. The electricity cost is, after all, competitive with the actual market price. The electricity and heat costs are lower or almost equal than other values reported for actual Rankine cycle cogeneration plants. (author)

    The Cogeneration Technology Alternatives Study (CTAS), a program undertaken to identify the most attractive advanced energy conversion systems for industrial cogeneration applications in the 1985-2000 time period, is described, and preliminary results are presented. Two cogeneration options are included in the analysis: a topping application, in which fuel is input to the energy conversion system which generates electricity and waste heat from the conversion system is used to provide heat to the process, and a bottoming application, in which fuel is burned to provide high temperature process heat and waste heat from the process is used as thermal input to the energy conversion system which generates energy. Steam turbines, open and closed cycle gas turbines, combined cycles, diesel engines, Stirling engines, phosphoric acid and molten carbonate fuel cells and thermionics are examined. Expected plant level energy savings, annual energy cost savings, and other results of the economic analysis are given, and the sensitivity of these results to the assumptions concerning fuel prices, price of purchased electricity and the potential effects of regional energy use characteristics is discussed.

    Full Text Available The aim of the study is to present an economic analysis of a micro cogeneration system using financial analysis (energy view and exergoeconomic analysis (exergy view. This system uses a natural gas-fueled 30 kW microturbine to generate electricity, and to produce hot water by recovering energy from the waste heat in the exhaust gases by using a heat exchanger, which serves as the drive source of an absorption chiller with a nominal capacity of 35 kW. In the financial analysis economic indicators such as payback, net present value and internal rate of return were used to verify the economic feasibility of this system, while in the exergoeconomic analysis, the Theory of Exergetic Cost was used to determine the exergetic monetary costs. A thermodynamic model was developed on the EES-32 (Engineering Equation Solver platform. On applying the financial analysis, the results showed that the micro cogeneration system is feasible with positive values of R$ 206,540.00 for NPV, 27% IRR and a 6-year payback. Based on the exergoeconomic analysis, the cogeneration system is also feasible since the monetary cost of the electricity is lower than that charged by the electricity company but this is only possible after the 5th year.

    Fermentation experiments were designed to elucidate the functional role of the redox microenvironment on volatile fatty acid (VFA, short chain carboxylic acid) production and co-generation of biohydrogen (H2). Higher VFA productivity was observed at pH 10 operation (6.3g/l) followed by pH 9, pH 6, pH 5, pH 7, pH 8 and pH 11 (3.5 g/l). High degree of acidification, good system buffering capacity along with co-generation of higher H2 production from food waste was also noticed at alkaline condition. Experiments illustrated the role of initial pH on carboxylic acids synthesis. Alkaline redox conditions assist solubilization of carbohydrates, protein and fats and also suppress the growth of methanogens. Among the carboxylic acids, acetate fraction was higher at alkaline condition than corresponding neutral or acidic operations. Integrated process of VFA production from waste with co-generation of H2 can be considered as a green and sustainable platform for value-addition.

    Nuclear desalination of seawater remains a very viable option to solving the perennial fresh water shortage problem along the coast of Ghana especially as Ghana prepares to install the first nuclear power plant. There is, therefore, the need for research to be conducted into nuclear seawater desalination technology as part of the nuclear power program of Ghana so as to develop the needed human resources in Ghana. In this research, cycle analysis of the cogeneration nuclear power plant was conducted to determine its efficiency and desalination steam requirements. An analytical model of the thermo vapour compression (TVC) desalination process was also developed to investigate the effect of design and operating parameters on parameters controlling the cost of producing fresh water from TVC process. Steady state mass and energy balances as well as empirical correlations derived from experiments were used to model the TVC, which was coupled to a cogeneration nuclear power plant to supply the needed steam for the desalination. The model was developed on a computer code, using FORTRAN language. The results showed that the thermal performance of the TVC desalination process improves with the efficiency of the cogeneration nuclear power plant but decreases with increasing steam consumption rates.

    Cogeneration turbines operate in different operation modes that considerably differ as to the working process conditions. In summer time, when heat demand is minimal, almost all steam flow passes through all turbine stages and enters into the condenser (condensing mode of operation). When heat supply is needed, the steam bleed-offs are used. The several last stages of the turbine (low-pressure part—LPP) have a control diaphragm at the inlet. When the heat supply is large, the diaphragm is maximally closed, and the entire steam flow, with an exception for a minimal ventilation flow is delivered to the steam bleed-offs (cogeneration mode). LPP flow path is designed for the optimal operation in the condensing mode. While running in cogeneration mode, the LPP operating conditions are far from optimal. Depending on the ventilation steam flow rate and outlet pressure, the LPP power can drop to zero or even become negative (ventilation mode). It is proposed to control an outlet steam pressure by using the heat pump that operates with steam. The heat pump energy consumption can be compensated and even exceeded by optimizing the steam expansion process in LPP. In this respect, operating conditions of cogeneration turbine LPPs during the cold season are analyzed. A brief description of a heat pump operating with steam is made. The possibility of increasing cogeneration turbine efficiency by using a steam heat pump is shown.

    The INPHO project aims at upgrading and optimizing the SAPHIR installation that is dedicated to the measurement (through the detection of photofission reactions) of radioactive wastes containing transuranium elements. Some modifications have been made during the phase I of the upgrading: -) the supply of power between the 2 parts of the accelerator has been modified. Now the setting of the beam energy does not imply to compensate for a phase shift; -) the vacuum level of the accelerator has been improved, it passed from 10{sup -6} torr to 7.10{sup -8} torr); and current measurers have been set on the electron line (there were no direct diagnostics previously). Other modifications are planned for the phase II of the upgrading. It concerns: -) the power supply of the electron gun; -) the control system; and the power supply of the klystron. In parallel with the phase II, feasibility studies have been led for the design of an electron line that will allow the electron-photon converter target to be as near as possible to the waste package to probe.

    Full Text Available The current upsurge of interest in street art with its direct approach to the city emphasizes the need to readdress public arts’ role within the wider social and cultural context. As it becomes routine to incorporate art works into city planning and city life, art has become both ‘safe’ and ‘user‐friendly’. On the one hand, art is subsumed and immersed into the wider culture through leisure and entertainment policies, socially engaged public art projects, community art and urban design. On the other hand, there are those works which deliberately intend to unsettle or confront the viewer. In recent years the term intervention has been ascribed to unorthodox art works in the public sphere which are often illicit, or at least non‐complicit in the prevailing hegemony. These practices are disruptive due to their enactment outside traditional art spaces, often in the streets. By occupying the streets, places of democracy and disjunction, these interventions transform public space back into a place of overt cultural and political expression. They also deliberately involve the inhabitants of the city by utilizing everyday spaces in ways which offer an unmediated sense of the artwork.

This helps members of the science team get a sense of place before proceeding, kind of the way a hiker pauses now and then to view the scenery. Scientists and engineers use panoramas like this to select interesting rocks and soils for further study and to plan a safe path for the rover. In this image mosaic, Spirit is pausing to take a good look around while descending due east toward a ridge nicknamed 'Haskin Ridge.' Before driving the rest of the way down, Spirit will take a panoramic image of the large, deep basin to the left of the ridge, labeled 'East Basin,' which was not visible from the summit. A longer-term destination is the prominent, round, platform-like feature labeled 'Home Plate.' This 360-degree panorama was assembled from images Spirit took with its navigation camera on the 651st martian day, or sol (Nov. 2, 2005), of its exploration of Gusev Crater on Mars.

    Recent instability in the Brazilian electrical energy supply, together with the re-structuring of the power sector and government initiatives to increase natural gas participation in the system have led to discussion over the possibility of implementing cogeneration plants that utilize natural gas as an energy source in power generating for use in cooling and heating systems. Given this context, the use of cogeneration plants is an alternative for service sector companies (such as retail centers, universities, schools, and hospitals) that would like to implement with the goal of producing electricity and cooling for indoor environmental climate control. In this study, an energetic analysis (based on the first law of thermodynamics) and an exergetic analysis (based on the second law) were performed on two cogeneration plants. (author)

    In the last years the fuel cell technology has been pointed out as a promising alternative for electricity generation. Compared to conventional energy conversion processes it presents great advantages, such as high efficiency, low gases emissions and the possibility to be applied in cogeneration systems, among others. The fuel cell converts the chemical energy of the fuel directly into electricity via an electrochemical process. The waste heat generated in the process can be recovered in cogeneration applications. In this article, preliminary results related to a Phosphoric Acid Fuel cell (PAFC) applied to hotels for power generation and hot water production are presented. The PAFC shows an electrical efficiency of about 40 per cent for power generation. In the cogeneration system proposed in this work, the global thermoelectric efficiency increased up to 73 per cent, when both electrical and thermal energy are considered. (author)

    Customarily, electricity is generated in a utility power plant while thermal energy is generated in a heating/cooling plant; the electricity produced at the power plant is transmitted to the heating/cooling plant to power equipments. These two separate systems waste vast amounts of heat and result in individual efficiencies of about 35%. Cogeneration is the sequential production of power (electrical or mechanical) and thermal energy (process steam, hot/chilled water) from a single power source; the reject heat of one process issued as input into the subsequent process. Cogeneration increases the efficiency of these stand-alone systems by producing these two products sequentially at one location using a small additional amount of fuel, rendering the system efficiency greater than 70%. This report discusses cogeneration technologies as applied to wood fuel fired system.

    Mexico has an industrial cogeneration potential very important, not evaluated or projected within its historical growth. The objective of the present work consist of studying the industrial cogeneration potential that exists in Mexico, as well as the economic and environmental savings that it would be achieved if one took advantage of this potential. As a result of the present work we can conclude that the cogeneration in Mexico offers a theoretical potential middle of 28,000 MWe to the 2007. It is estimated an economic saving potential in the construction of generation infrastructure electrical, for the high stage of its utilization of almost 7000 million of dollars and a stage of emissions reduction of 2007- 21.37% instead of 2007- 0.35% for the industrial sector of the country. These prognoses can be obtained, as long as the government changes vision to handle this subject as a measure of energy saving, and substitute it by the policy of complement the development of the national electrical sector. [Spanish] Mexico tiene un importante potencial de cogeneracion industrial que no ha sido evaluado ni proyectado dentro de su crecimiento historico, por ello, el objetivo de este trabajo consiste en estudiar y conocer los ahorros economicos y ambientales que se podrian lograr si se aprovechara dicho potencial. Como resultado, se muestra que la cogeneracion en Mexico ofrece un potencial teorico medio de 28,000 MWe al ano 2007. Se estima tambien un ahorro economico en la construccion de infraestructura de generacion electrica para el escenario alto de su aprovechamiento de casi 7 000 mdd, y un escenario de reduccion de emisiones para el sector industrial del pais de un 0.35% a un 21.4% para el ano 2007. Estos pronosticos se pueden lograr, siempre y cuando el gobierno cambie la vision de manejar este tema como una medida de ahorro de energia, y la sustituya por la politica de complemento al desarrollo del sector electrico nacional.

    The municipal utilities of Basel (IWB) are in the process of building a 30 MW wood-fired cogeneration plant in the city of Basel, Switzerland, a project idea that was initially proposed by visionaries from the forest sector. Despite recent doubts about its profitability due to unforeseen major increases in investment costs, the plant is attractive both politically and from a business perspective, as several goals related to the increased use of renewable energy can be achieved simultaneously. Moreover, significant woody biomass resources are awaiting further exploitation in the Basel region, which could help to improve markedly the cost effectiveness of forest maintenance. In this paper, we study the history and some of the characteristics of the project from a socio-economic perspective. Of particular interest to our study is the early involvement of a large number of stakeholders with different interests. The project constitutes a pioneering project that could serve as an important non-Scandinavian model for similar projects in other parts of Switzerland, but also in Western and Central Europe as a whole. The lengthy decision-making and planning process offers interesting insights into the socio-economic drivers and barriers of large-scale bioenergy projects in urban settings, where wood heating systems are in general not as well established as in the countryside. We find that the interest of regional forest owners to tackle the problem of over-aged and largely unprofitable forests, coupled with a political climate that (1) favours green energy projects and (2) provides incentives for the municipal utility to produce more green energy from sources other than hydropower, have been the two main success factors for developing this particular biomass plant project.

    The fuels from oil and natural gas play an important role, not only in the sector of primary energy, but also in almost all the other sectors of the economy, due to its imbrication as insum of these. The use of the natural gas will have great expansion in Brazil, motivated for the Government decision to increase the participation of this fuel in the Brazilian energy matrix from 4% to 12% up to 2010. Then, it's so important the investment in new technologies and also the improvement. In order to reach the objective related to increase the consumption of natural gas in the energy matrix, and to propose solutions to attend the electric requirements, of heat and refrigeration, using natural gas as primary power plant, the Center of Gas Technologies; CTGAS, in partnership with PETROBRAS and the Fockink Group, has developed the first modular system of generation and co-generation of energy by natural gas of low power, of easy installation and shipment with the characteristics techniques to take care of to companies or industrial sectors that consummate this band of power. The equipment generates 35 kW/55 kVA of electric energy, 7TR (Ton of Refrigeration) of energy for refrigeration and posses the ability to heat 2200 l/h of water in the temperature of 85 deg C. The equipment will be able to produce electric and thermal energy simultaneously, from an only fuel, the natural gas. The main objective of this work is to present the main phases of development of the archetype, functions techniques of the co-generator and its field of performance in the market of systems for generation and co-generation of energy by natural gas of low power.

    MAZDA Motor Corp. planed the construction of a 20.5MW co-generation plant in 1991 for responding to an increase in power demand due to expansion of the Hofu factory. On introduction of this co-generation plant, it was decided that the basic system would adopt the following. (1) A circulating fluidized bed boiler which can be operated by burning multiple kinds of fuels with minimum environmental pollution. (2) A heat accumulation system which can be operated through reception of a constant power from electric power company despite a sudden and wide range change in power demand. (3) A circulating-water exchange heat recovery system which recovers exhaust heat of the turbine plant as the hot water to be utilized for heating and air-conditioning of the factory mainly in winter. Power demand in MAZDA`s Hofu factory changes 15% per minute within a maximum range from 20MW to 8MW. This change is difficult to be followed even by an oil burning boiler excellent in load follow-up. The circulating Fluidized bed boiler employed this time is lower in the follow-up performance than the oil boiler. For the newly schemed plant, however, load averaging system named a heat accumulation system capable of responding fully to the above change has been developed. This co-generation plant satisfied the official inspection before commercial operation according the Ministerial Ordinance in 1993. Since then, with regard to the rapid load following, which was one of the initial targets, operation is now performed steadily. This paper introduces an outline of the system and operation conditions. 10 refs.

  10. The Design and Commissioning of a Micro-cogeneration Testing Facility

    Boucher, Evan

    The simultaneous production of heat and electricity onsite to serve residential loads can potentially yield a reduction in operating costs, primary energy use and related emissions over traditional technologies which meet these loads separately. Proper sizing and operation of units along with their required buffering and auxiliary systems are critical to the realization of both economical and environmental performance objectives. Further research is required to develop strategies to integrate micro-cogeneration technologies into Canadian residences as issues related to device type, capacity, design of balance of plant components, and controls remain largely unresolved. Building performance simulation is a highly flexible, and time-efficient method to systematically explore and evaluate different design options; however, the validity of the conclusions resulting from simulation based studies are dependent on the accuracy and reliability of the models employed. In order to support ongoing research relating to micro-cogeneration technologies through simulation based activities, a facility capable of subjecting units to controlled electrical and thermal loading was designed and commissioned to collect performance data suitable for device-specific model calibration. The facility can also be configured to provide realistic thermal and electrical loading to complete micro-cogeneration systems including thermal storage and auxiliary heating to evaluate the performance of complete systems. It provides a platform to experimentally investigate appropriate configurations to integrate units into residences through variations in the balance of plant components and control strategies. This thesis describes the design of the facility including its hardware, instrumentation, data acquisition and controls systems. Also described are experiments that were conducted during the commissioning phase to assess system level performance, to identify and correct hardware integration issues

    The palm oil mills are characterized by the availability of considerable amounts of by-products of high-energy value such as empty fruit bunches (EFB), fibers, shells and liquid effluents with high content of organics called palm oil mill effluent (POME). A palm oil mill produces residues equivalent to almost three times the amount of oil produced by biomass, showing a huge potential for increasing the power efficiency of the plants and installed power, mainly by the use of by-products in cogeneration plants with high steam parameters and by reducing steam consumption in process. The objective of this paper is to present the results of the study about the cogeneration potential for three representative palm oil mills located in two important palm oil producing regions in Colombia (South-America), fifth palm oil producers of the world. The sizing of the cogeneration system was made assuming it operation during the greatest possible number of hours throughout the year (based on the seasonal availability of fruit) considering parameters for the steam at 2 MPa and 350 C, using a condensing-extraction turbine. The balance of mass and energy was made by using the Gate Cycle Enter Software, version 5.51, to estimate the potential of electricity generation. The results showed that for fresh fruit bunch (FFB) processing capacities between 18 and 60 t FFB h{sup -1}, it is possible to have surplus power ranging between 1 and 7 MW, if the plants are self-sufficient in electric energy and steam for process. With an average Capacity Factor (approximately 0.4), it is possible to expect a generation index of 75 and 160 kWh t{sup -1} FFB when the processing plant is operating or shutdown, respectively, 3 or 4 times better than when a traditional system with a back-pressure steam turbines is used. This analysis used up to 60% of EFB produced in plant as fuel, considering its value as fertilizer for the palm crop. Several economic conditions were considered to estimate the economic

    The recent Hunters Point, San Francisco power plant siting process in California represents the first time that environmental justice has arisen as a major power plant siting issue. Intervenors argued that the siting process was racially and economically biased and were supported by leading environmental justice activists at the Golden Gate Law School`s Environmental Justice Clinic, a leading thinker in this field. The applicant argued that environmental justice charges cannot realistically be made against a modern natural-gas energy facility with state-of-the-art environmental controls. The applicant also argued that environmental justice concerns were fully addressed through the extensive environmental and socioeconomic review carried out by California Energy Commission staff. After extensive testimony and cross-examination, the Commission agreed with the applicant. This case has important lessons for companies that could be charged with environmental justice violations and environmental justice activists who must decide where to most effectively target their efforts. This paper reviews the proceeding and its lessons and makes recommendations regarding future applicability of environmental justice issues to the power generation sector. The authors represented the applicant in the facility siting proceeding.

    Considering the new legal frame on cogeneration in Mexico, the possibility of heat and electricity supply required by the sugar mills to be made by an independent cogenerator of the sugar mill, operating with the sugar cane bagasse and agricultural sugar cane wastes, has been evaluated. Such modern cogenerator would be characterized, besides operating in an independent way of the sugar mill, by the use of high efficiency equipment in its process of heat and electricity generation. In this sense the Comision Nacional para el Ahorro de Energia (CONAE) through its Coordination Program and the Instituto de Investigaciones Electricas (IIE) carried out a joint project to determine the technical and economical viability that the sugar industry maintains the present sugar production without the need of burning fuel oil, installing adjacent to every sugar mill, a modern cogeneration system, operated by independent producers, that using sugar cane bagasse and agricultural sugar cane wastes, allows the supply of all the steam and electricity required by the sugar mill, and additionally can add firm capacity and the supply of electric power to the national grid, during the grinding season as well as out of grinding season. [Espanol] En consideracion al nuevo marco juridico de la cogeneracion en Mexico se ha evaluado la posibilidad de que el suministro de calor y electricidad requerido por los ingenios azucareros sea proporcionado por un cogenerador independiente de la planta de azucar, el cual opere utilizando el bagazo y residuos agricolas caneras (biomasa canera). Dicho cogenerador moderno se caracterizaria, ademas de operar de manera independiente a la planta de azucar, por el uso de equipos de alta eficiencia en su proceso de produccion de calor y electricidad.

    The potential contribution of locus coeruleus (LC)-derived noradrenaline (NA) in the motor activating and rewarding effects of cocaine (15 mg/kg) were assessed following administration of the neurotoxin N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP-4). In Experiment 1, administration of 10 mg/kg of DSP-4 similarly to substantial denervation with 50 mg/kg of DSP-4 significantly attenuated the activating effects of cocaine during the first cocaine-paired training session (30 min) in the conditioned place preference (CPP) apparatus. Only administration of the higher dose (50 mg/kg) of DSP-4 attenuated line crossings during the last training, while both doses reduced rearings. Thus, both minor and substantial denervation of LC reduced but did not abolish locomotion activating effect of cocaine. Cocaine CPP as measured by increment of time spent in the previously cocaine-paired chamber during drug-free conditions before and after cocaine-paired trainings was clearly revealed only in animals with intact projections from the LC, and was entirely absent after a large lesion of LC projections by DSP-4 (50 mg/kg). Because recovery of noradrenaline levels by the end of experiment did not allow assessment of the efficacy of the neurotoxin, the effect of DSP-4 pre-treatment on the acute psychomotor effect of cocaine was re-examined in an independent experiment (Experiment 2). Near complete denervation of the LC projections again reduced the effect of cocaine, but the lower dose of DSP-4 had no effect, suggesting that small lesions of the LC do not have a robust impact. Overall, this study demonstrates that both unconditioned and conditioned effects of cocaine depend upon the integrity of LC projections.

  4. Evaluation of potential for cogeneration of electricity and process heat in North Carolina. Final report, June 1, 1978-May 31, 1979

    Energy Technology Data Exchange (ETDEWEB)

    1979-01-01

    The objective of this study was to enable North Carolina to more efficiently utilize available energy than would be possible without additional cogeneration. Effective use of cogeneration can ease the requirement for utility capital and power plant sites and, by reducing fuel usage, can lead to less environmental damage. The study used the National Emissions Data System data bank and the North Carolina Boiler Registry to identify potential candidates for cogeneration and to then ascertain the magnitude of the potential in existing, new, and expanded facilities as a function of cogeneration impediment elimination. The survey uncovered 372 MW of operable cogeneration capacity in North Carolina in 15 plants. An estimate of the potential for expansion of cogeneration by firms presently operating in North Carolina amounted to 130 MW. This estimate was based on current conditions of fuel costs, electricity rates, standby charges, and investment tax credit. Much information is provided concerning industry and utilities in North Carolina, fuel usage by industry, and barriers to cogeneration. Recommendations are summarized.

    2002-11-01

    Cogeneration of heat and electricity is being considered by the South Dakota Soybean Processors for its facility in Volga, South Dakota, and a new facility to be located in Brewster, Minnesota. The Energy & Environmental Research Center has completed a feasibility study, with 40% funding provided from the U.S. Department of Energy's Jointly Sponsored Research Program to determine the potential application of firing biomass fuels combined with coal and comparative economics of natural gas-fired turbines. Various biomass fuels are available at each location. The most promising options based on availability are as follows. The economic impact of firing 25% biomass with coal can increase return on investment by 0.5 to 1.5 years when compared to firing natural gas. The results of the comparative economics suggest that a fluidized-bed cogeneration system will have the best economic performance. Installation for the Brewster site is recommended based on natural gas prices not dropping below a $4.00/MMBtu annual average delivered cost. Installation at the Volga site is only recommended if natural gas prices substantially increase to $5.00/MMBtu on average. A 1- to 2-year time frame will be needed for permitting and equipment procurement.

    According to the third conference of parties (COP3), Japan has set a target of reducing greenhouse gas emissions by 6% by the year 2010. Many believe that the bulk utilization of fossil fuel influences to the damaging environmental effect. The objective of this paper is to propose an effective method for this goad which is possible to clarify a noticeable utilization of renewable fuel in a micro gas turbine cogeneration system in cold region. Moreover, analysis of renewable fuel, biogas production indicates that production amount becomes largest in hot season, while the total heat energy demand is lowest on during three years. Biogas storage is also adapted for the delay between peak energy supply and demand. Biogas hydrate formation is examined by resource from laboratory experiments and simulation of integration into an existing cogeneration arrangement. The proposed system can be successfully supported the use and reuse of renewable fuel for providing to substantial emission and clean development mechanism for reducing greenhouse gas emission.

  7. A New Approach for Assigning Costs and Fuels to Cogeneration Products

    Full Text Available

    Cogeneration plants generate more than one product (e.g., electricity and steam using to some extent common fuel(s and equipment items. Several approaches have been suggested in the past for assigning the costs associated with these common equipment items and fuels to the products of the plant. Some of these approaches use exergy-based or thermoeconomic methods. The results, however, may vary within a wide range.

    This paper presents a new exergy-based approach for assigning the fuel(s used in a cogeneration plant to the individual products of the plant. Combined with a thermoeconomic analysis, this approach provides the costs associated with the product streams. The new approach is more flexible, i.e. it allows engineers to actively participate in the fuel and cost assigning process. As expected, the results obtained with this approach differ from the results obtained from any of the previous approaches, including the exergetic cost theory and all previous thermoeconomic approaches. The application of the new approach is demonstrated using a combined heat and power plant.

    In this paper the strategies are formulated and evaluated, taking into account the internal and external aspects of the cogeneration in Mexico that foment their development in the medium term (two or four years). In the formulation of strategies a matrix DAFO (Weaknesses, Threats, Strengths and Opportunities) is employed and in the evaluation is applied the procedure of analytical hierarchical structuring. The future on the cogeneration in the next years will depend on diverse factors, among which can be mentioned: the legal frame; the financial situation of the interested companies; the outsourcing of financing; the prices of the electricity and fuels, as well as their availability, among others.

El futuro de la cogeneracion en los proximos anos dependera de diversos factores, entre los que se pueden mencionar: el marco legal; la situacion financiera de las empresas interesadas; las fuentes externas de financiamiento; los precios de la electricidad y de los combustibles, asi como su disponibilidad, entre otros.

  9. Temperature effect on electrochemical promotion of syngas cogeneration in direct-methane solid oxide fuel cells

    Science.gov (United States)

    Huang, Ta-Jen; Huang, Meng-Chin

    Syngas cogeneration in direct-methane solid oxide fuel cells with Ni-yttria-stabilized zirconia (YSZ) anodes was studied with temperature varying from 700 to 900 °C. A phenomenon of electrochemical promotion of bulk lattice-oxygen extraction from the YSZ electrolyte was observed. With increasing temperature, this promotion effect increases while both the rate enhancement ratios of CO and CO 2 formations decrease. The activation energy of CO and CO 2 formation under close circuit is lower than that under open circuit. The activation energy for the lattice-oxygen extraction from the YSZ bulk is higher than that for the oxygen transport through the YSZ bulk. The process of lattice-oxygen extraction from YSZ is rate determining in direct-methane oxidation under the condition of either close circuit or open circuit. The dependence of CO formation rate on the oxygen supply rate is stronger than that of CO 2 formation rate. Electrochemical promotion of bulk lattice-oxygen extraction enhances syngas cogeneration.

    We present a practical tool that employs entropy generation minimization (EGM) approach for an in-depth performance evaluation of a co-generation plant with a temperature-cascaded concept. Co-generation plant produces useful effect production sequentially, i.e., (i) electricity from the micro-turbines, (ii) low pressure steam at 250 °C or about 8-10 bars, (iii) cooling capacity of 4 refrigeration tones (Rtons) and (iv) dehumidification of outdoor air for air conditioned space. The main objective is to configure the most efficient configuration of producing power and heat. We employed entropy generation minimization (EGM) which reflects to minimize the dissipative losses and maximize the cycle efficiency of the individual thermally activated systems. The minimization of dissipative losses or EGM is performed in two steps namely, (i) adjusting heat source temperatures for the heat-fired cycles and (ii) the use of Genetic Algorithm (GA), to seek out the sensitivity of heat transfer areas, flow rates of working fluids, inlet temperatures of heat sources and coolant, etc., over the anticipated range of operation to achieve maximum efficiency. With EGM equipped with GA, we verified that the local minimization of entropy generation individually at each of the heat-activated processes would lead to the maximum efficiency of the system. © 2012.

    Full Text Available This paper presents a concept of the parallel connection of a nuclear power plant fitted to provide heat for district heating application, with the CHP and heat plants existing in the supply region, in this case with the heating systems of Wejherowo and Gdynia. Presented variant proposes to add heat to a nuclear power plant’s total output by supplying heat exchangers with the steam from bleeders of low pressure (LP turbine stage and from the crossover pipe between its high pressure (HP and intermediate pressure (IP stages. A detailed diagram of the EPR nuclear turbine system adapted to supply district heat is also presented. Also determined are the formulas for: electric power output of a nuclear CHP plant; electric power generated strictly in cogeneration, and the decrease in the electric power and energy resulting from the operation in cogeneration mode. Finally, the profitability (competitiveness criteria for a nuclear power plant adapted to supply district heat in a selected heat supply region were proposed.

    This paper presents the performance investigation of a cogeneration plant equipped with an efficient waste heat recovery system. The proposed cogeneration system produces four types of useful energy namely: (i) electricity, (ii) steam, (iii) cooling and (iv) dehumidification. The proposed plant comprises a Capstone C30 micro-turbine which generates 24 kW of electricity, a compact and efficient waste heat recovery system and a host of waste heat activated devices namely (i) a steam generator, (ii) an absorption chiller, (iii) an adsorption chiller and (iv) a multi-bed desiccant dehumidifier. The numerical analysis for the host of waste heat recovery system and thermally activated devices using FORTRAN power station linked to powerful IMSL library is performed to investigate the performance of the overall system. A set of experiments, both part load and full load, of micro-turbine is conducted to examine the electricity generation and the exhaust gas temperature. It is observed that energy utilization factor (EUF) could achieve as high as 70% while Fuel Energy Saving Ratio (FESR) is found to be 28%.

    The paper investigates the influence of tolerating the shortage of energy supplies on the economy of cogeneration systems in consideration of energy demand as random variables. To make a reasonable investigation into the influence, an optimal unit sizing method proposed by the authors is adopted after it is extended to this case so that it enables probability distributions of energy demand to be considered. In the method, equipment capacities and maximum contract demands of utilities such as electricity and natural gas are determined so as to minimize the expected value of the annual total cost in consideration of operation strategies for all the estimated energy demand under the toleration of the shortage of energy supplies. Numerical studies are carried out on cogeneration systems installed in a hotel or an office building with changing shortage rates of energy supplies as parameters. Through the studies, it is found the expected systems' economy is improved even if the shortage rates of energy supplies are very small, and that the improvement of the office building is larger than that for the hotel.

    Long before the neologism ``Cogeneration`` was coined (around 1978), UEM`s Chambiere Power Plant -- which dates back to the turn of the century -- was already supplying the city of Metz with combined heat and power. In 1992, Chambiere experienced a major turning point in its history with the installation of a new unit based on one MS 6001B ``Heavy Duty`` gas turbine. This model, rated 38 MWe-ISO and burning natural gas or fuel oil, has become the core of a new cogeneration unit exhibiting outstanding performance: efficiency higher than 80 percent (LHV) providing a 20 percent energy saving in comparison to a conventional plant; low pollutant emissions (NO{sub x}, CO, HC) and low contribution to the greenhouse effect (CO{sub 2}). The gas turbine has been equipped with two steam injection devices, for DeNO{sub x} and power augmentation, respectively, resulting in a very flexible system. After describing the power plant and giving its main achievements in the fields of energy and emissions, the paper briefly presents several improvements intended to protect both the turbine and the environment.

    Full Text Available Co-generation systems, together with absorption refrigeration and thermal storage, can result in substantial benefits from the economic, energy and environmental point of view. Optimization of operation of such systems is important as a component of the entire optimization process in pre-construction phases, but also for short-term energy production planning and system control. This paper proposes an approach for operational optimization of energy supply systems with small or medium scale co-generation, additional boilers and heat pumps, absorption and compression refrigeration, thermal energy storage and interconnection to the electric utility grid. In this case, the objective is to minimize annual costs related to the plant operation. The optimization problem is defined as mixed integer nonlinear and solved combining modern stochastic techniques: genetic algorithms and simulated annealing with linear programming using the object oriented “ESO-MS” software solution for simulation and optimization of energy supply systems, developed as a part of this research. This approach is applied to optimize a hypothetical plant that might be used to supply a real residential settlement in Niš, Serbia. Results are compared to the ones obtained after transforming the problem to mixed 0-1 linear and applying the branch and bound method.

    Waste Processors Management, Inc. (WMPI), along with its subcontractors Texaco Power & Gasification (now ChevronTexaco), SASOL Technology Ltd., and Nexant Inc. entered into a Cooperative Agreement DE-FC26-00NT40693 with the U. S. Department of Energy (DOE), National Energy Technology Laboratory (NETL) to assess the technoeconomic viability of building an Early Entrance Co-Production Plant (EECP) in the United States to produce ultra clean Fischer-Tropsch (FT) transportation fuels with either power or steam as the major co-product. The EECP design includes recovery and gasification of low-cost coal waste (culm) from physical coal cleaning operations and will assess blends of the culm with coal or petroleum coke. The project has three phases. Phase I is the concept definition and engineering feasibility study to identify areas of technical, environmental and financial risk. Phase II is an experimental testing program designed to validate the coal waste mixture gasification performance. Phase III updates the original EECP design based on results from Phase II, to prepare a preliminary engineering design package and financial plan for obtaining private funding to build a 5,000 barrel per day (BPD) coal gasification/liquefaction plant next to an existing co-generation plant in Gilberton, Schuylkill County, Pennsylvania. The current report covers the period performance from January 1, 2003 through March 31, 2003. Phase I Task 6 activities of Preliminary Site Analysis were documented and reported as a separate Topical Report on February 2003. Most of the other technical activities were on hold pending on DOE's announcement of the Clean Coal Power Initiative (CCPI) awards. WMPI was awarded one of the CCPI projects in late January 2003 to engineer, construct and operate a first-of-kind gasification/liquefaction facility in the U.S. as a continued effort for the current WMPI EECP engineering feasibility study. Since then, project technical activities were focused on: (1

    In this communication it is spoken of the cogeneration in large processing power stations with or without electricity surplus, the characteristics of combined cycle power plants and a comparative analysis in a graph entitled Sale price of electricity in combined cycle and cogeneration power plants. The industrial plants, such as refineries, petrochemical, breweries, paper mills and cellulose plants, among others, with steam necessities for their processes, have the technical and economical conditions to cogenerate, that is, to produce steam and electricity simultaneously. In fact, many of such facilities that exist at the moment in any country, count on cogeneration equipment that allows them to obtain their electricity at a very low cost, taking advantage of the existence steam generators that anyway are indispensable to satisfy their demand. In Mexico, given the existing legal frame, the public services of electricity as well as the oil industry are activities of obligatory character for the State. For these reasons, the subject should be part of the agenda of planning of this power sector. The opportunities to which we are referring to, are valid for the small industries, but from the point of view of the national interest, they are more important for the large size facilities and in that rank, the most numerous are indeed in PEMEX, whereas large energy surplus and capacity would result into cogenerations in refineries and petrochemical facilities and they would be of a high value, precisely for the electricity public service, that is, for the Comision Federal de Electricidad (CFE).

    In this paper we apply exergoeconomic principles to perform a comparative analysis of the use of internal combustion engines or gas turbines as prime movers of cogeneration plants. A preliminary comparison of these movers can be obtained by analysing them individually, considering the complete utilization of the generated products rated on a common exergetic basis. However, when these movers are integrated in a cogeneration plant, it is necessary to perform a global system analysis, which will consider the coupling between generation capacity and demand, under the design conditions. The design of a cogeneration plant should, ideally, consider all the aspects that affect its performance. In this paper we take into account several aspects which are not normally collectively considered in similar analyses encountered in the literature. Specifically, the comparative procedure considers the electrical tariff on an hourly basis, the electrical and thermal load profiles, the influence of the environmental conditions on the performance of the prime movers, sizing and operation mode options to meet plant loads, part-load efficiency, different criteria for cost partitioning, and, finally, the effect of size on plant cost. Once the operating conditions of the cogeneration plant are defined, the procedure attributes costs to all the fluxes, allowing for the identification of the ranges of capacity where each mover is economically advantageous. We apply the procedure to the energetic supply analysis of a typical process of Brazilian shopping centers. (author)

    Full Text Available Implementation of co-generation of thermal and electrical energy in district heating systems often results with higher overall energy efficiency of the systems, primary energy savings and environmental benefits. Financial results depend on number of parameters, some of which are very difficult to predict. After introduction of feed-in tariffs for generation of electrical energy in Serbia, better conditions for implementation of co-generation are created, although in district heating systems barriers are still present. In this paper, possibilities and effects of implementation of natural gas fired co-generation engines are examined and presented for the boiler house that is a part of the district heating system owned and operated by the Faculty of Mechanical Engineering in Niš. At the moment, in this boiler house only thermal energy is produced. The boilers are natural gas fired and often operate in low part load regimes. The plant is working only during the heating season. For estimation of effects of implementation of co-generation, referent values are taken from literature or are based on the results of measurements performed on site. Results are presented in the form of primary energy savings and greenhouse gasses emission reduction potentials. Financial aspects are also considered and triangle of costs is shown.

    A novel reaction mechanism of H{sub 2} and CH{sub 4} cogeneration from water hyacinth (Eichhornia crassipes) was originally proposed to increase the energy conversion efficiency. The glucose and xylose hydrolysates derived from cellulose and hemicellulose are fermented to cogenerate H{sub 2} and CH{sub 4} by two-step anaerobic fermentation. The total volatile solid of hyacinth leaves can theoretically cogenerate H{sub 2} and CH{sub 4} yields of 303 ml-H{sub 2}/g-TVS and 211 ml-CH{sub 4}/g-TVS, which dramatically increases the theoretical energy conversion efficiency from 19.1% in only H{sub 2} production to 63.1%. When hyacinth leaves are pretreated with 3 wt% NaOH and cellulase in experiments, the cogeneration of H{sub 2} (51.7 ml-H{sub 2}/g-TVS) and CH{sub 4} (143.4 ml-CH{sub 4}/g-TVS) markedly increases the energy conversion efficiency from 3.3% in only H{sub 2} production to 33.2%. Hyacinth leaves, which have the most cellulose and hemicellulose and the least lignin and ash, give the highest H{sub 2} and CH{sub 4} yields, while hyacinth roots, which have the most ash and the least cellulose and hemicellulose, give the lowest H{sub 2} and CH{sub 4} yields.

    Cogeneration or Combined Heat and Power (CHP) is an advantageous technique based on the simultaneous utilisation of electricity and heat produced. For this purpose existing energetic technologies are used. Cogeneration is based on the thermodynamics principle that producing electricity by combustion process means, at the same time, producing waste heat that can be useful utilised. Three main advantages can be lay out in a cogeneration plant: 1. High efficiency (the global efficiency is often around 80-90%). 2. Economic profit (pay back time is usually not longer than 2-4 years). 3. Low pollutant emissions (as a consequence of the high efficiency less fuel is burned for generating the same quantity of electricity). In this report are analysed various aspects of cogeneration (technical and economical) and the conditions influencing is development. Some figures on the european and national situation are also given. Finally are presented the research and development activities carried out by Italian National Agency for new Technology Energy and the Environment Energy Department to improve the efficiency and the competitiveness of this technology.

  6. local alternative sources for cogeneration combined heat and power system

    Agll, Abdulhakim Amer

    Global demand for energy continues to grow while countries around the globe race to reduce their reliance on fossil fuels and greenhouse gas emissions by implementing policy measures and advancing technology. Sustainability has become an important issue in transportation and infrastructure development projects. While several agencies are trying to incorporate a range of sustainability measures in their goals and missions, only a few planning agencies have been able to implement these policies and they are far from perfect. The low rate of success in implementing sustainable policies is primarily due to incomplete understanding of the system and the interaction between various elements of the system. The conventional planning efforts focuses mainly on performance measures pertaining to the system and its impact on the environment but seldom on the social and economic impacts. The objective of this study is to use clean and alternative energy can be produced from many sources, and even use existing materials for energy generation. One such pathway is using wastewater, animal and organic waste, or landfills to create biogas for energy production. There are three tasks for this study. In topic one evaluated the energy saving that produced from combined hydrogen, heat, and power and mitigate greenhouse gas emissions by using local sustainable energy at the Missouri S&T campus to reduce energy consumption and fossil fuel usage. Second topic aimed to estimate energy recovery and power generation from alternative energy source by using Rankin steam cycle from municipal solid waste at Benghazi-Libya. And the last task is in progress. The results for topics one and two have been presented.

    1998-04-03

    Advances within power cycles, integration of cycles, and combination of existing technologies are the possible ways to improve performance of small- and medium-scale power technology. Identification and development of new energy conversion technologies and systems for distributed power generation applications are the objectives of the New Energy Conversion Technologies (NECT) programme of the Netherlands Agency for Energy and Environment (Novem). The part of the programme, which is dedicated to the development of new and improved combinations of existing energy conversion technologies, defines the structure of this thesis. At the beginning, the basic thermodynamic cycles and their specific features are described. Because no single cycle can offer high efficiency due to the intrinsic limitations and the impossibility to operate within a broad temperature range, combined and advanced cycles are addressed. Combined cycles do not suffer from the drawbacks of the single cycles, since the heat rejected by the topping cycle is utilized by the bottoming one, and better performance can be obtained. The basic cycles are combined according to their temperature level: high-temperature cycles are good candidates for the topping application, and medium- or low-temperature cycles for bottoming. Of the combined cycles considered, each cycle is outlined and its schematic diagram is given. In addition to the combined cycles, improvements within a particular cycle are discussed. The scope of the NECT programme covers power and heat production, so industrial cogeneration is assessed in various configurations (steam boiler, gas turbine, heat pumps) and operating modes. Subsequently, several technologies, which are selected for further development within the NECT programme, are analyzed in detail. One of the configurations is the Joule/Joule combined cycle, which consists of an existing gas turbine and an air bottoming turbine. The bottoming cycle adds 20-30% to the power output, which

    An increased interest in the notion of place has evolved in interaction design based on the proliferation of wireless infrastructures, developments in digital media, and a ‘spatial turn’ in computing. In this article, place-specific computing is suggested as a genre of interaction design...... that addresses the shaping of interactions among people, place-specific resources and global socio-technical networks, mediated by digital technology, and influenced by the structuring conditions of place. The theoretical grounding for place-specific computing is located in the meeting between conceptions...... examples of place-specific computing are presented from a series of pilot studies, conducted in close collaboration with design students in Malmö, Berlin, Cape Town and Rome, that generated 36 design concepts in the genre. Reflecting on these examples, issues in the design of place-specific computing...

  19. Application of reburn techniques for NOx reduction to cogeneration prime movers. Volume 1. Rich-burn engine application. Final report, June 1984 to July 1988

    The report describes the results of a design and experimental program to develop a post-combustion NOx control technique for gas-fired I.C. engines and gas turbines as applied to cogeneration. Emissions and performance data of both rich-burn and lean-burn engines were used to develop a conceptual reburner design to be placed between an engine and a waste heat boiler. This reburner design was then modeled for testing in a 100,000 Btu/hr subscale test facility. Parametric testing achieved 50 percent NOx reduction at a fuel fraction of 30 percent for rich-burn and mid-O2 range engine exhausts. Lean-burn NOx reductions were limited to 35 percent at the same fuel fraction. With the addition of a NiO catalyst in the rich zone, NOx reductions of up to 90 percent were achieved in the subscale testing. A full-scale system was designed, fabricated, and tested on a 150 kW Caterpillar engine. NOx reductions of 40 to 50 percent were achieved without a catalyst; reductions of up to 75 percent were achieved with a NiO catalyst.

    Advances in coal-fueled gas turbine technology over the past few years, together with recent DOE-METC sponsored studies, have served to provide new optimism that the problems demonstrated in the past can be economically resolved and that the coal-fueled gas turbine can ultimately be the preferred system in appropriate market application sectors. The objective of the Solar/METC program is to prove the technical, economic, and environmental feasibility of a coal-fired gas turbine for cogeneration applications through tests of a Centaur Type H engine system operated on coal fuel throughout the engine design operating range. The five-year program consists of three phases, namely: (1) system description; (2) component development; (3) prototype system verification. A successful conclusion to the program will initiate a continuation of the commercialization plan through extended field demonstration runs.

    Citing the supply utility of a township as an example the author outlines the various steps involved in analysing the risk and the amount of insurance cover required in the conversion of a district heating plant. Unforeseen events which as a result of failures due to damage require the plant to be shut down per force lead to a higher level of capital employment due to repair costs, shutdowns and losses of income from the supply of electricity and heat. Mentioning the conversion of a straight district heating plant into an up-to-date cogenerating plant the author shows how such risks can be determined with the aid of accurate risk analyses and adequately covered.

    The objective of this study is to clarify safety characteristics of a High Temperature Gas-Cooled Reactor (HTGR) for the pipe rupture accident. Japan Atomic Energy Agency (JAEA) has been developing the analytical code for the safety characteristics of the HTGR and carrying out design study of the gas turbine high temperature reactor of 300MWe nominal-capacity for hydrogen production, the GTHTR300C (Gas Turbine High Temperature Reactor 300 for Cogeneration). A numerical analysis of heat and mass transfer fluid flow with multi-component gas mixture has been performed to obtain the variation of the density of the gas mixture, and the onset time of natural circulation of air. From the results obtained in this analysis, it was found that the duration time of the air ingress by molecular diffusion would increase due to the existence of the recuperator in the GTHTR300C system.

    The co-generation of acetylene and hydrogen from the hydrolysis of calcium carbide and calcium hydride was investigated as part of a unique carbide-based fuel system intended for high-temperature fuel cells. To gain better control of this highly energetic reaction, glycerin was used to coat the reactant particles to form slurry prior to their reaction with water. This process was shown to moderate the rate of gas production, as well as to provide a means for preparing slurry that could be pumped into the reactor vessel. It was also observed that the presence of calcium hydroxide, a by-product of hydrolysis, lowered the solubility of acetylene resulting in a higher initial flow rate due to less acetylene being dissolved in solution. However, the buildup of calcium hydroxide with time inhibited the hydrolysis of both calcium carbide and calcium hydride causing the acetylene and hydrogen flow rates to decrease. (author)

    This work aims at to analyze the re powering of medium sized sugar and alcohol plants located in the Southeast area of Sao Paulo State. Through a study case considering a standard unit that processes ten thousand tons of sugarcane per day, simulations were made using a mathematical model denominated Modelo de Despacho Hidrotermico, which supports the decision process for the expansion of electric energy offers. As a result of these simulations, it was possible to get the standard dispatch profile for such cogeneration plants, expressed by a medium capacity factor of 89%, demonstrating, therefore, the significant participation that these units can have in the energy context. Furthermore, a brief discussion about the energy price and capital return time is introduced, emphasizing the attractiveness of this kind of enterprise. (author)

  6. The Surplus-Electric-Power Trade of the Cogeneration by PPS

    The report modeled an electricity interchange trade by a PPS (Power Producer and Supplier) and a cogeneration, and evaluated the interchange trade using the numerical example. The PPS and the CGS user behave economically themselves in the model. It is new that not an electric power company but PPS trades the surplus electric power. From the numerical example, the effect of electricity price and gas prices is different between commercial sector and industrial sector when maximizing the PPS profits. An electricity interchange gives profits to three groups (the PPS, the CGS user, and the unspecified general user) who participate in trades. However, it was shown that the PPS cannot gain only few portions of the whole interchange profits although the PPS determines the purchase price for the CGS user.

    In recent years, fossil fuels such as petroleum, coal, and natural gas have become limited resources. In addition, global warming due to carbon dioxide (CO{sub 2}) emission has become a serious environmental issue. Since current living and economical standards depend strongly on fossil energy sources, it is necessary to realize a new society that utilizes biomass as a source of energy. With this background, in 2005, we manufactured a practical Stirling engine using biomass fuels. And we proposed a unique co-generation system using a practical Stirling engine that utilizes woody biomass fuel such as sawdust, firewood, and wood pellets. A burner uses the woody biomass fuel to heat the air in the expansion room to about 650 C and a water cooling system cools the air in the compression room to about 40 C. Under these operating conditions, the new engine generated about 3kW of electricity. (orig.)

    Biomass-based ethanol and nuclear power are two viable elements in the path to U.S. energy independence. Numerous studies suggest nuclear power could provide a practical carbon-free heat source alternative for the production of biomass-based ethanol. In order for this coupling to occur, it is necessary to examine the interfacial requirements of both nuclear power plants and bioethanol refineries. This report describes the proposed characteristics of a small cogeneration nuclear power plant, a biochemical process-based cellulosic bioethanol refinery, and a thermochemical process-based cellulosic biorefinery. Systemic and interfacial issues relating to the co-location of either type of bioethanol facility with a nuclear power plant are presented and discussed. Results indicate future co-location efforts will require a new optimized energy strategy focused on overcoming the interfacial challenges identified in the report.

    Aznar S.A. is a textile factory especially sensitive to electricity distribution failures. They produce the subsequent shut down at the manufacturing process and several hours of maintenance tasks. A cogeneration plant has been installed to provide electricity and thermal energy to the process. Since the location is far from Natural Gas pipelines the system includes fuel-oil as energy source. Annual electricity production will be 23.300 MWh and 6.400 MWh of them will be exported into the grid. Fuel-oil consumption at the heat exchanger is reduced by 47%, but the whole factory consumption increases a 247% due to the high consumption of the engine. This increase is compensated by revenues from selling electricity and electricity savings. These facts, together with maintenance cost saving leads to a pay back time of 3.3. years. (Author)

    The paper deals with an innovative (120 kWe, 195 kWt) natural gas (NG) combined heat and power (CHP) system, at present under development, which has been set up at the FIAT Centre of Research (CRF), Turin, Italy. The main characteristics of the CHP system are: the use of an automotive derived internal combustion engine, a high part load electrical efficiency due to a variable speed operation strategy and an advanced exhaust gas after-treatment to meet the most stringent pollutant emission regulations. In the paper, the electrical efficiency and pollutant emissions of the new CHP unit are compared with those of some traditional small-scale cogeneration systems. Some comparison criteria and performance indices which are, in the authors' opinion, the most representative of the real operative conditions, have been proposed to evaluate the performance of the different technologies.

    Full Text Available The support of combined heat and power production systems has gained policy attention, because these are often considered to be less polluting and more efficient than conventional energy conversion systems. As a consequence, the potential market for these energy systems that contribute to reduce greenhouse gas emissions and to enhance energy security on a national level, is shifting from large-scale existing units to small and micro-size emerging technologies. This paper presents a numerical model based on a cost-benefit analysis used to design an optimal cogeneration system for a small-scale building application, considering the Portuguese context and the comparison with the harmonized efficiency reference values for the separate production of electricity and useful heat. The model includes the identification of the objective function terms (i.e., the elements involved in the financial analysis across the system lifetime and the economic evaluation of costs and benefits of the combined heat and power production system. The economic viability of cogeneration systems significantly depends on system technology, client energy requirements and support schemes implemented in the respective countries. A strategic approach is necessary to adequately embed the new technology as a feasible solution in terms of investment and operational costs. Only by matching the energy supply to the needs and expectations of the energy users, it will be possible to improve the market competitiveness of these alternative power production plants. The optimal solution disclosed a positive annual worth, which is higher if the carbon emission savings are monetized. In addition, the optimal system represents a more efficient way to produce useful heat and electricity (i.e. a positive primary energy saving and to reduce gas emissions. A cost-benefit analysis can be applied for the techno-economic evaluation of a CHP system by assessing the monetary socio-environmental costs

    This paper presents the performance investigation of a temperature cascaded cogeneration plant, shortly in TCCP, equipped with an efficient waste heat recovery system. The TCCP or cogeneration system produces four types of useful energy namely (i) electricity, (ii) steam, (iii) cooling, and (iv) dehumidification and distilled water by utilizing single energy source. The TCCP comprises a Capstone C30 micro-turbine that generates nominal capacity of 26 kW of electricity, a compact and efficient waste heat recovery system and a host of waste heatactivated devices namely (i) a steam generator, (ii) an absorption chiller, (iii) an adsorption desalination system, and (iv) a multi-bed desiccant dehumidifier. The analysis is performed under different operation conditions such as heat source temperatures, flow rates of heat transfer fluids and chilled water inlet temperatures. The only single heat source for TCCP is obtained from exhaust gas of micro-turbine and it is channeled to a series of waste heat recovery heat exchangers to steam and hot water at different temperatures. Hot water produced by such a compact heat exchangers is the driving heat source to produce steam of 15 kg/h, cooling of 2 Rton, dehumidification of 2 Rton, and distilled water of 0.7 m3/day. A set of experiments, both part load and full load, of micro-turbine is conducted to examine the electricity generation and the exhaust gas temperature. It is observed that energy utilization factor could achieve as high as 70% while fuel energy saving ratio is found to be 28%. © 2013 Desalination Publications. All rights reserved.

    The selection of a cogeneration steam turbine unit (STU) for the reconstruction of power units with a T-250/300-23.5 turbine is substantiated by the example of power unit no. 9 at the cogeneration power station no. 22 (TETs-22) of Mosenergo Company. Series T-250 steam turbines have been developed for combined heat and power generation. A total of 31 turbines were manufactured. By the end of 2015, the total operation time of prototype power units with the T-250/300-23.5 turbine exceeded 290000 hours. Considering the expiry of the service life, the decision was made that the reconstruction of the power unit at st. no. 9 of TETs-22 should be the first priority. The main issues that arose in developing this project—the customer's requirements and the request for the reconstruction, the view on certain problems of Ural Turbine Works (UTZ) as the manufacturer of the main power unit equipment, and the opinions of other project parties—are examined. The decisions were made with account taken of the experience in operation of all Series T-250 turbines and the results of long-term discussions of pressing problems at scientific and technical councils, meetings, and negotiations. For the new power unit, the following parameters have been set: a live steam pressure of 23.5 MPa and live steam/reheat temperature of 565/565°C. Considering that the boiler equipment will be upgraded, the live steam flow is increased up to 1030 t/h. The reconstruction activities involving the replacement of the existing turbine with a new one will yield a service life of 250000 hours for turbine parts exposed to a temperature of 450°C or higher and 200000 hours for pipeline components. Hence, the decision has been made to reuse the arrangement of the existing turbine: a four-cylinder turbine unit comprising a high-pressure cylinder (HPC), two intermediate pressure cylinders (IPC-1 & 2), and a low-pressure cylinder (LPC). The flow path in the new turbine will have active blading in LPC and IPC-1
