Estimation the Performance of Gas Turbine Power Station with Air Cooling Fog System

Abstract

The purpose of this study is to shed light on the fog system to cool the inside air to the compressor in the gas station to generate electricity. Where it mainly focused on the suitability of the fog system to the hot Iraqi climate throughout the summer period, a simulation analysis of the operation of the gas turbine unit using a fog system at an ambient temperature in the range of 25-55 °C was conducted in the southern Baghdad second station. The fog system proved to be highly effective in raising the effective power, the thermal efficiency and the effective efficiency coefficient of the gas turbine unit as well as a apparent decrease in the specific air flow rate, the specific fuel consumption and the specific heat consumption in the gas turbine unit compared to not using fog system for cooling and for the same operating conditions.
