Thermal Analysis of Steam Power Plant of High Capacity

Abstract

Steam power plants are widely utilized throughout the world for electricity generation, and coal is often used to fuel these plants. To utilize coal more effectively and competently in electricity generation processes the energy optimization is required. Thus the thermal analyses of different components are performed to improve efficiency and performance. Present work deals with the thermal analysis of 600 MW steam power plant. The energy efficiency of boiler, turbine and condenser are found to be 63.05, 48.25 and 92.67 respectively. Similarly the respective exergy efficiencies are 52.69, 88.25 and 18.5 for boiler, turbine and condenser. The results indicate the exergy reduction of steam is high in condenser showing low efficiency. The energy loss of steam in the condenser can be compensated by adopting binary power generation cycles.
