Energy analysis of 171 mw combined cycle power plant in Bangladesh

Abstract

The Kushiara Combined Cycle Cogeneration Plant is investigated in this research by energy and exergy analyses. Energy analysis using key operating conditions is used to evaluate the basic thermodynamic properties of the structures. To evaluate thermodynamic inefficiencies in the system and to direct potential changes in the facility, exergy destructions inside the system and exergy losses to the atmosphere are examined. The research included evaluating the thermodynamic properties of twenty-four node points in a thermal power plant unit, as well as measuring exergy values for each node. Exergies that were lost or destroyed were then measured. On the basis of the received data, the equipment and materials were compared on a table. In the boiler, the highest rate of exergy loss corresponded to 38.3 percent. The powerplant's average second law efficiency amounted to 50.7 percent. The method of measurement and the conclusions obtained are assumed to be applicable to other thermal power plants.
