Abstract
Comparative and Exergetic Study of a Gas Turbine System with Inlet Air Cooling
Highlights
Some of the important parameters that influence the performance of the gas turbines are the ambient temperature, air pressure and moisture
The aim of this study is to investigate the influence of the inlet air cooling system on the gas turbine performance by energy and exergy analyses
It is concluded that the net power output of the gas-turbine system increases at lower inlet air temperatures, and based on the mean values, exergetic efficiency and exergy destruction ratio were found as 37.35% and 33.02%, respectively
Summary
Some of the important parameters that influence the performance of the gas turbines are the ambient temperature, air pressure and moisture. As the temperature of air increases the density of air decreases, and the mass flow rate of compressed air diminishes. The power output of the gas turbine is proportional to the mass flow rate of air. Various cooling methods are present for reducing the gas turbine inlet temperature. These methods are mainly evaporative coolers, spray inlet coolers or fogging systems, and mechanical refrigeration or chillers [1, 2]. Among these methods, fogging systems have become increasingly popular recently because of their effectiveness and low cost
