This report presents an in-depth exergy and energy analysis of a 350 MW coal-fired power plant, examining its major components including the boiler, turbines, condenser, and pumps. The study, based on mechanical equations and calculations, identifies the boiler as the site of major exergy destruction, with an exergy efficiency of approximately 40.4%. The analysis highlights the significant energy losses within the plant, particularly in the boiler, and evaluates the efficiencies of other components like the high-pressure turbine and condensate pump. Through a review of literature and detailed methodology, including plant component modeling, the report aims to pinpoint areas for efficiency improvement, focusing on the boiler, low-pressure turbine, and condenser. The findings underscore the relationship between plant efficiency and carbon dioxide emissions and emphasize the importance of improving current energy systems for sustainable development. The report also references the Rankine cycle and HELE technologies to improve efficiency.
