Abstract

This study presents a thermodynamic analysis of a 220MW thermal plant using its design and operating data. The plant was simulated using HYSYS version 3.2 simulator software. The whole plant was sectionalised into three, each comprising of different units to determine the contribution of each unit to the efficiency and irreversibility of the plant. The maximum exergy loss of 168MW was in the boiler unit. The energetic and exergetic efficiencies were studied for different parameters such as turbine inlet temperature and pressure and fuel flow rate. The overall efficiency of the plant in terms of the first law of thermodynamics (energetic) was 24.1% and the second law analysis (exergetic) was 23.3%.
