Performance Evaluation Of Gas Turbine By Reducing The Inlet Air Temperature

ABSTRACT Performance of a gas turbine is mainly depends on the inlet air temperature. The power output of a gas turbine depends on the mass flow rate of air. Now days the atmosphere temperature is hot so the air is less density the mass flow rate will reduce and automatically the power output will reduce. A reduce of 1C temperature of inlet air increases the power output by approximately 0.7MW. To reduce the inlet air temperature by using the various techniques evaporative coolers vapor compression chillers and absorption chillers. In this paper the performance of 100MW model capacity gas turbine is compared by reducing the inlet air temperature from 35C to 25C. The results are taken from the GT PRO software and this software is mainly used for power plant design.
