Effect of Condenser Backpressure on Power Plant Heat Rate and Thermal Efficiency

Acharya Chirag, Nirvesh Mehta, Jaspal Dabhi


Thermal power plants are used to generate electricity by using fossil fuels. Optimizing operating condition can considerably improve condensing and vacuum of condenser hence efficiency. Steam exhaust pressure affects the performance of turbine. Variation in condenser backpressure about design can impact the economic operation of a unit with respect to heat rate. The study has been carried out for the load of 210 MW GSECL thermal power plant.
