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.
Download or read book Emissions Reduction Through Upgrade of Coal Fired Power Plants Learning from Chinese Experience written by Association internationale pour l'évaluation du rendement scolaire and published by . This book was released on with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Coal is the principal fuel for the generation of electrical power globally. It is the leading source of power generation in OECD countries and the dominant fuel source behind economic growth in non-OECD countries. However, while providing over 40% of the world's electricity, it is responsible for more than 70% of the CO2 arising from electricity generation. The IEA carried out a project to examine the potential to improve the performance of existing coal-fired plants. Two power units in China were selected to showcase measures that would improve their net efficiency. The results built on the efficiency gains made under China's national energy efficiency improvement programme and demonstrated the enormous potential to improve performance, with each percentage point increase capable of reducing CO2 emissions by many millions of tonnes over a unit's operational lifetime. Experiences learned in China can be applied to improving coal-fired power plant efficiency worldwide

Download or read book Industry Perspectives on Increasing the Efficiency of Coal fired Power Generation written by and published by . This book was released on 1997 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Independent power producers will build a substantial fraction of expected new coal-fired power generation in developing countries over the coming decades. To reduce perceived risk and obtain financing for their projects, they are currently building and plan to continue to build subcritical coal-fired plants with generating efficiency below 40%. Up-to-date engineering assessment leads to the conclusion that supercritical generating technology, capable of efficiencies of up to 45%, can produce electricity at a lower total cost than conventional plants. If such plants were built in Asia over the coming decades, the savings in carbon dioxide emissions over their lifetime would be measured in billions of tons. IPPs perceive supercritical technology as riskier and higher cost than conventional technology. The truth needs to be confirmed by discussions with additional experienced power engineering companies. Better communication among the interested parties could help to overcome the IPP perception issue. Governments working together with industry might be able to identify creative financing arrangements which can encourage the use of more efficient pulverized clean coal technologies, while awaiting the commercialization of advanced clean coal technologies like gasification combined cycle and pressurized fluidized bed combustion.

Download or read book Improving the Energy Efficiency of a Mid size Power Plant by Reduction in Auxiliary Power and Improved Heat Transfer written by Jeffrey A. Green (‡e author) and published by . This book was released on 2014 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study incorporates the potential use of Variable Frequency Drives on various motors as well as areas of improved heat transfer in an older, mid-sized coal fired power plant. In power plants, fluid flow rates are often controlled using dampers or valves while the motors that power the pumps stay at full speed resulting in a significant amount of wasted electrical power; energy is also lost due to poor heat recovery prior to gases leaving the system. By examining pump usage as well as additional heat available for recovery, potential energy savings will be determined. Preliminary results of five motors suggested for variable frequency drive application show annual savings that total 31.1 GWh, resulting in a 1.66% increase in overall plant efficiency. Total project costs are near $2 million resulting in a simple payback period of less than two years assuming 0.04 $/kWh. For every degree reduction of the flue gas temperature by means of heat recovery that is reused elsewhere in the cycle, 2 Billion BTU of coal would be saved annually. One realistic scenario suggested heat recovery resulting in a 120°F degree reduction of flue gas temperature amounting to a 2.54% increase in cycle efficiency.
