Abstract: In this study, Seyitomer coal-fired power plant was analysed by the enhanced exergy method. In this regard, enhanced exergy analysis of coal combustion was introduced first by defining ideal and unavoidable conditions. The real conditions of the plant were obtained by measurements. As a conclusion, an improvement potential of approximately 33.11% was determined for the overall system. The highest avoidable exergy destruction was determined in the boiler group with 29.46%. The endogenous part of this destruction was calculated as 6.77% where the exogenous part was approximately 22.69%. The improvement potential of the boiler group was determined as approximately 19.09%. The second highest avoidable exergy destruction was determined as the turbine group with approximately 16.35%. The endogenous part of this destruction was calculated as approximately 5.70% where the exogenous part was 10.65%.
