Abstract

This study involved the performance of energy and exergy analysis on a 200 MW Steam cycle power plant (SCPP). The aim is to investigate the effect of using different number of feed water heaters (FWHs) on the cycle performance. Several simulation analyses were conducted in this study on a MATLAB platform. The computer model used was based on natural gas combustion, enthalpy balances, energy balances, and entropy changes of the SCPP. The real case study was simulated on a validated model of the SCPP for Shahid Montazeri Power Plant. The exergy destroyed within each components system and the exergy efficiency are determined to study the irreversibility of the system and identify the chances for the enhancement of the power system. Based on the result of the analyses, the energy and exergy efficiencies of the SCPP were determined to be about 37.52 % and 41.7 %, respectively. In the SCPPs, the combustion chamber (boiler) contributes the highest exergy destruction rate (around 48 % of the exergy value of the gas) among the main components of the power system.
