© Survey Of Thermodynamic Methods To Improve The Efficiency Of Coal-Fired Electricity Generation Rosen, MA; Dincer, I PROFESSIONAL ENGINEERING PUBLISHING LTD, PROCEEDINGS OF THE INSTITUTION OF MECHANICAL ENGINEERS PART A-JOURNAL OF POWER AND ENERGY; pp: 63-73; Vol: 217 King Fahd University of Petroleum & Minerals Summary Some of the more significant thermodynamic methods to improve the efficiency of coal-based electricity generation technologies are surveyed and examined, focusing on minor practical improvements that can be undertaken with limited effort and cost. Two categories of methods are examined. The first is efficiency-improvement techniques such as better maintenance and control, application of exergy and related analysis methods, and use of computer-based simulation, analysis, optimization, and design. The second category includes efficiency-improvement measures for devices, including steam generators, condensers, reheaters, and regenerative feedwater heaters. A case study is presented. It is concluded, for coal-fired electricity generation plants, that (i) many useful techniques exist (especially exergy analysis) and should be used for identifying and designing efficiency improvements, and (ii) the many possible measures to improve efficiency should be weighed against other factors and where appropriate implemented. Where larger efficiency increases are sought, improvements applicable over longer time frames and of a broader nature should be investigated.
