Climate Effects on Cooling Degree-Hours and Evaporative Cooling of Gas Turbine

Dayyabu Gambo Kofar-Bai and Qun Zheng
Abstract—Increase demand of power during peak load hours necessitates the need to raise gas turbine power plant performance especially in a region or station with persistant high temperature and low relative humidity, in this paper climatic data of some particular stations in Nigeria were modeled, cooling degre-hours obtained were simulated on brayton simple cycle and evaporative cooling of gas turbine, performance effects were studied and presented, the results shows an increase in the gas turbine power and efficiency and decrease of compression work on the compressor, evaporative cooling retain the net output power of the gas turbine to 25.86 MW at higher temperature when the demand is at peak and increases the efficiency to 29.8 MW when the demand is low and the ambient temperature at lowest level. Cooling degree-hours decrease with increase in base temperature and with known cooling degree-hours in a station,net power can not only be boost but the operational cost of evaporative cooling of gas turbine can be reduce.

Index Terms—Evaporative cooling, cooling degree-hours, climate and gas turbine.
