Performance of gas turbine co-generation power desalting plants under varying operating conditions in Kuwait

Recent developments in gas turbines have led to their utilization to carry both base and emergency loads in single purpose power plants as well as in cogeneration (e.g. power and desalting) plants. Gas turbines are usually rated at certain environmental design conditions (e.g. low ambient temperatures) which differ from hot environments like that in Kuwait. Consequently, their actual power output and thermal efficiency are much lower than their rated design values during hot and humid weather that prevails most of the year in Kuwait. This study is concerned with the prediction of gas turbine cogeneration (power/desalting) plant performance under different environmental and loading conditions.
