Two-Stage Evaporative Inlet Air Gas Turbine Cooling

Gas turbine inlet air-cooling (TIAC) is an established technology for augmenting gas output and efficiency, especially in hot regions. TIAC using evaporative cooling suitable hot, dry regions; however, the limited by ambient wet-bulb temperature. This study investigates two-stage under harsh weather of Riyadh city. The system consists indirect direct stages. In stage, air precooled water cooled a tower. adiabatic saturation cools air. investigation was conducted GE 7001EA model. Thermoflex software used to simulate different systems including evaporative, hybrid absorption refrigeration vapor-compression systems. Comparisons performance parameters turbines were conducted. added annual profit payback period estimated
