Comparative studies are presented to determine the effect of the turbine blade cooling method on the Advanced Humid Air Turbine (AHAT) system performance. In AHAT systems, two kinds of fluids can be used as a coolant: air extracted from the compressor and humid air. Three types of turbine blade cooling systems are evaluated using the in-house heat cycle simulator. As a result, the thermal efficiency is improved 1.7 percentage points by using the humid air cooling method. The possibility of remodeling a typical mid-size simple cycle gas turbine for use in AHAT systems is examined. A remodeled AHAT system, which can be realized by adjusting the compressor intake flow rate, has 1.3 percentage points higher thermal efficiency than the combined cycle system using the same core gas turbine.
