Gas Turbine Power Augmentation in Hot Season by Inlet Air Cooling "Effects of Humidity on Gas Turbines Performance"

Gas Turbines are power generating machines the output of which drops with increase of ambient temperature. However, with cooling the inlet air of the gas turbine, it is possible to compensate part of this power output loss. It was anticipated that the amount of power gained by cooling the inlet air, would be in accordance with the manufacturer characteristic curve. However, as an experience in REY Power Plant proved differently, we prompted t o s tudy t he r eason of this fact. Our aim in this paper is to study one of the most important reasons for such a behavior, i.e., the effect of humidity on the performance of Gas Turbines.
