Simulation of a gas turbine plant using Evaporative cooler

Abstract

This research work focus on the simulation of a gas turbine power plant using evaporative cooler. Aspen HYSYS software was used for the simulation of the gas turbine with and without cooling system using the actual operating data for performance evaluation. The results obtained on the simulation of the gas turbine at ambient air temperature of 29 0C without the use of cooling system showed that ambient air temperature decreases the net power output, thermal efficiency and power output. However, when the gas turbine was incorporated with air intake cooling system, there was drop in ambient air temperature which resulted to an increase in net power output, thermal efficiency and power output.
