  7. Abstract:
  8. Nowadays, gas turbines are from the most widely used devices in terms of power generation. According to their vital role in suppling electrical power required for daily life and their widespread application in power plants, tremendous efforts have been made to improve the efficiency of gas turbine working cycle. One of the most applicable methods to optimize a gas turbine is to cool the compressor inlet air. Applying an absorption chiller is a wisely technique especially when it comes to hot and humid weather condition. In this thesis, effects of applying an absorption chiller with specified technical facts on the performance of gas turbines, which are now functional in Kish Island power plant, have been studied, The power plant output enhancement based on gas turbines efficiency improvement has been calculated. Due to Kish Island weather condition and considering its dew point temperature. The required ton of refrigeration necessary for cooling the air entering gas turbine compressor has been measured. Analyzing results of above calculations show that for every degree of reduction in the intake air temperature there would be around 0.75% improvement in power output and 0.035% in thermal efficiency of gas turbines installed in Kish Island power plant. The total improvement in the power output when the system is cooled down about 12 degrees, is about 11%; which after estimating indispensable investment to purchase required equipment to set up this proposal and calculating the revenues of this scheme in Kish Island power plant, it has been concluded that duration of investment return is about 3 to 5 years which makes this proposal economic justifiable
