Book excerpt: A major deliverable of the U.S. Department of Energy (DOE) project ''Engineering Development of Advanced Coal-Fired Low-Emissions Boiler Systems'' (LEBS) is the design of a large, in this case 400 MWe, commercial generating unit (CGU) which will meet the Project objectives. The overall objective of the LEBS Project is to dramatically improve environmental performance of future pulverized coal fired power plants without adversely impacting efficiency or the cost of electricity. The DOE specified the use of near-term technologies, i.e., advanced technologies that partially developed, to reduce NO(subscript x), SO2 and particulate emissions to be substantially less than current NSPS limits. In addition, air toxics must be in compliance and waste must be reduced and made more disposable. The design being developed by the ABB Team is projected to meet all the contract objectives and to reduce emission of NO(subscript x), SO2 and particulates to one-fifth to one-tenth NSPS limits while increasing net station efficiency significantly and reducing the cost of electricity. This design and future work are described in the paper.
Download or read book Clean and Efficient Coal fired Power Plants written by Heinz Termuehlen and published by American Society of Mechanical Engineers. This book was released on 2003 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the evolution toward advanced coal-fired power plants. Advanced power plants with an efficiency level of 45% are today commercially available and even more efficient plants are in their development phase. Considering that presently many pulverized coal-fired power plants operate with an efficiency of about 32%, an improvement of more than 40% specific coal consumption and CO2 discharge can be achieved. Before trying to apply as a secondary measure the use of carbon sequestration, it seems that this 40% specific CO2 discharge reduction as a primary measure can much easier be achieved. The effect of power generation on the environment can be drastically improved by the use of flue gas cleanup systems in advanced pulverized coal-fired power plants (SO2 emission reduction from 40 to 1.4 lb/MWh and NOx emission reduction from 7.5 to 0.64 lb/MWh). With an increased number of coal-fired plants, CO2 discharge and emissions can be reduced, even with an increase of electric power generation in the US by 38% over the next 20 years. Even though the book concentrates on pulverized coal-fired power plants, it also discusses and compares other options like fluidized-bed combustion and coal gasification.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Energy (DOE) was given a mandate in the 1992 Energy Policy Act (EPACT) to pursue strategies in coal technology that promote a more competitive economy, a cleaner environment, and increased energy security. Coal evaluates DOE's performance and recommends priorities in updating its coal program and responding to EPACT. This volume provides a picture of likely future coal use and associated technology requirements through the year 2040. Based on near-, mid-, and long-term scenarios, the committee presents a framework for DOE to use in identifying R&D strategies and in making detailed assessments of specific programs. Coal offers an overview of coal-related programs and recent budget trends and explores principal issues in future U.S. and foreign coal use. The volume evaluates DOE Fossil Energy R&D programs in such key areas as electric power generation and conversion of coal to clean fuels. Coal will be important to energy policymakers, executives in the power industry and related trade associations, environmental organizations, and researchers.

Download or read book Monte Carlo Simulation of Pulverized Coal fired Power Plants written by Teerawat Sanpasertparnich and published by . This book was released on 2007 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was found from the study that the major influential parameters were moisture content in coal, steam pressures throughout a turbine system, boiler efficiency, temperature of preheated air, and temperatures of both main steam and reheated steam. The obtained parametric effects were quantified and translated into a series of empirical correlations of the net efficiency that could be readily utilized by power industries and engineers. Besides the net efficiency, the magnitude of the energy penalty due to the CO2 capture integration was evaluated and also the optimal level of the CO2 capture target was identified. The sensitivity analysis for cost of electricity was also performed in this study based on different scenarios, i.e., base subcritical pulverized coal-fired power plant without the CO2 capture, subcritical pulverized coal-fired power plant with the CO2 capture using alkanolamine solvent, base supercritical pulverized coal-fired power plant without the CO2 capture, and supercritical pulverized coal-fired power plant with the CO2 capture using alkanolamine solvent.

Available in PDF, EPUB and Kindle. Book excerpt: Under the US Department of Energy (DOE) project 'Engineering Development of Advanced Coal-Fired Low-Emission Boiler Systems' (LEBS) the ABB team developed the design of a 400 MWe advanced pulverized coal fired electric generating system. The work and the results are described in the paper. Early work included concept development and evaluation of several subsystems for controlling the emission of SO2, NO(subscript x), particulates and for reducing wastes. Candidate technologies were then evaluated in various combinations as part of complete advanced supercritical power generation systems. One system was selected for the design of the advanced generating system. Pilot scale testing is now being conducted to support the design of subsystems. The design meets the overall objective of the LEBS Project by dramatically improving environmental performance of pulverized coal fired power plants without adversely impacting efficiency or the cost of electricity. Advanced technologies will be used to reduce NO(subscript x), SO2, and particulate emissions to one-fifth to one-tenth of current NSPS limits. Air toxics will be in compliance, and wastes will be reduced and made more disposable. Net station (HHV) efficiency can be increased to 45 percent without increasing the cost of electricity.

Download or read book Thermal Power Plants written by Paweł Madejski and published by BoD – Books on Demand. This book was released on 2018-05-02 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for electricity and heat production is still largely covered by conventional thermal power plants based on fossil fuel combustion. Thermal power stations face a big challenge to meet the environmental requirements constantly keeping high process efficiency and avoiding lifetime shortening of critical components. In recent years, many activities have been observed to reduce pollutant emissions and optimize performance in thermal power plants. Increased share of renewable sources of energy in domestic markets enforces flexible operation and fast adjustment to actual demand. Gas power plants start to play a very important role in this process, allowing for rapid change of load and emission reduction. Operation under changing load together with keeping emissions at the accurate level requires constantly introducing new solutions and technologies as well as carrying out many research and development activities for optimization of the electricity and heat production process. The edited book is aimed to present new technologies, innovative solutions, measurement techniques, tools and computational methods dedicated to thermal power plants in the light of new trends and challenges.

Available in PDF, EPUB and Kindle. Book excerpt: Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.
