In the present work, exergy analysis of a coal-based thermal power plant is done using the operating data of a210MW thermal power plant under operation in eastern region of India. The entire power plant cycle is split up into tenthermal components for the analysis in order to analyze and compare the exergy destruction, % exergy destruction andsecond law efficiencies of the system and their components at full load as well as at part load conditions. The above analyseswere carried out at 100%, 75% and 60% of operating load to investigate the performance of the total power cycle and theirconstituting components in order to obtain the sources and causes of irreversibility’s as well as the variations in exergyefficiency under different operating conditions. It has been observed that the boiler causes the maximum exergy destructionat all loads under study. The contribution of the deaerator comes next followed by turbine and condenser while thecontribution of the feed water heaters and pumps is the least among the selected components.
