Abstract: Supercritical coal-based 660 MW plant is analysed to estimate the irreversibility at different atmospheric conditions. The overall outcomes indicated that the boiler has the highest exergy destruction in the system followed by the condenser. The exergy destruction increases with the increase in the atmospheric temperature and decreases with the decrease in the atmospheric temperature. The exergy destruction of the boiler is 1,198 MW followed by the exergy destruction of turbine 50.7 MW at 35°C, in Indian climate condition. At 20°C atmospheric temperature exergy destruction of boiler decreases at the rate of 2% while at 40°C it increases at the rate of 0.67%. Similarly, at 20°C atmospheric temperature exergy destruction of turbine decreases at the rate of 12.6% while at 40°C the value increases at the rate of 7.9%.
