| Coal is the key fuel for power generation in the Supercritical Rankine cycle. Exergy, a universal measure has the work potential or quality of different forms of energy of energy in relation to a given environment. In this paper, an exergy analysis has carried out to the supercritical power plant tells us how much useful work potential or exergy, supplied to the input to the system under consideration has been consumed by the process. A computer code has developed for exergy to analyses the supercritical cycle without reheat as well as with single reheat. The temperature and pressure inlet to the turbine and exhaust pressure from the turbine are identified as key parameters in this analysis. Both first law efficiency and exergetical efficiency have studied at various temperature and pressure inlet to the turbine. Irreversibility as well as Fractional exergy loss of all the components has also been studied. To decrease exergy loss of supercritical power plant, effects of pump discharge pressure increases, effects of steam turbine discharge pressure decreases and effects of steam temperature increases. First law efficiency is increases with increase in temperature at a given pressure. Exergy efficiency is increases with increase in temperature and pressure. It is found that both the efficiencies increases more in temperature rise than the pressure rise in the turbine inlet. Both Irreversibility and Fractional exergy losses in the boiler is reducing with increase in temperature.
