Power augmentation modeling of gas turbines via inlet compressor fogging with consideration of humidity effect on cycle elements

One of effective and important parameters on gas turbine output power is the ambient air temperature and increase of 1 degree centigrade of this parameter decreases output power of total cycle about 0. 6 to 0. 9 percent. Compressor inlet cooling is a useful way to increase of turbine power output. In this paper different ways of compressor inlet cooling such as evaporative cooling and refregerative cooling method are reviewed and at the end، direct jetting method (fogging method) is focused. Additionally thermodynamic modeling of cycle elements are studied and water jetting effects on operating parameters of GE - F5 gas turbine of Mashhad Power plant with consideration of cooling effect and humidity in combustion chamber and combustion modeling with humidity effect are presented. This study shows that 22 ℃ compressor inlet air cooling prevents power losing of total power plant cycle about 18. 79 percent in optimum case of operating.
