Energy and Exergy Analysis of a 3500 MW Coal Fired Thermal Power Plant using Cycle-Tempo

This study deals with an energy and exergy analysis of a coal fired 3500 MW thermal power plant located in South India. The platform used for simulation and analysis is Cycle-Tempo. In this article, the parameters of mass flow rate and temperatures at different state points of the thermal power plant were validated using the simulations carried out in CycleTempo. It was found from the analysis the operating parameters like temperatures, flow rates etc. Obtained using CycleTempo fall within an acceptable range of error. Maximum exergy loss was found to occur in the combustor (36.5%), and the least exergy loss occurred in the de-aerator (0.13%). Optimization of the power plant was carried out, and the energy and exergy efficiency values obtained for the power plant were 34.35% and 33.64%.
