A Review - Effect of Cooling System on the Efficiency and Output Power Gas Turbine
Keywords:
Gas Turbine, Cooling Inlet Air, Output Power TurbineAbstract
Gas turbines are machines that work directly with ambient air, then anything that causes a change in the inlet air condition, effect on turbine efficiency. Relative humidity, Mean sea level and environment temperature have a direct effect on gas turbine efficiency. In this research, reviews the type and effect of cooling system on the efficiency and out power turbine. Cooling the turbine inlet air (even by a few degrees) can increase power output substantially. This is because cooled air is denser, giving the turbine a higher mass-flow rate and resulting in increased turbine output and efficiency - even as much as 0.4% per degree Fahrenheit or about 0.7% per degree Celsius. Typically a 1° F temperature increase will result in a 0.5% decrease in power.
