Exergy analysis of a 250 MW power plant is done in this study. Thermal performance analysis using MATLAB calculation tool has been done. Exergy destruction phenomenon and Exergetic efficiency is calculated for various components of 250 MW coal fired subcritical power plant. The calculated overall plant exergy efficiency is evaluated 34.75%. Besides, results also concluded that exergy destruction takes place in the steam generator 490.76 MW (93.07%) followed by the other components. The comparative study of heat loss ratio with respect to varying plant load is performed out of which condenser contribute to have major heat loss ratio. The outcomes of this research study will be beneficial for future researchers.
