Parametric Study and Analysis of Varying the Condenser Pressure in Thermal Power Plant
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 12
Abstract
In this study, the energy and exergy analysis of an ideal Rankin cycle with reheat is presented. The primary objectives of this paper are to analyze the system components separately and to identify and quantify the sites having largest energy and exergy losses at cycle. In addition, the effect of varying the condenser pressure on this analysis will also be presented. The performance of the plant was estimated by a component-wise modeling and a detailed break-up of energy and exergy losses for the considered plant has been presented. Energy losses mainly occurred in the condenser where 2126KW is lost to the environment while nothing was lost from the boiler system because it assumed adiabatic. The percentage ratio of the exergy destruction to the total exergy destruction was found to be maximum in the boiler system 86.27% and then condenser and stack gas 13.73%. In addition, the calculated thermal efficiency was 38.39 % while the exergy efficiency of the power cycle was 45.85%. The boiler is the major source of irreversibilities. For improvement the power plant efficiency the effect condenser pressure has been studied.
