This paper describes advanced utilization of moisture in gas turbine systems for the purpose of improving thermal efficiency and output. We have proposed and been developing AHAT(Advanced Humid Air Turbine) system. The AHAT system is a system which uses existing mutual technologies and aims highperformance equal to that of the HAT system. Comparative calculations results on the small-scale AHAT system are presented. All results are evaluated by the in-house heat cycle simulator, which performs mass and energy balancing based on enthalpy calculations. As a result, AHAT system has 1.27 times larger output and 1.63 times higher thermal efficiency than the simple cycle system. The possibility of remodeling a gasturbine designed for AHAT system (recuperative or simple cycle system) for use in other systems is also examined. As a result, a gas turbine designed for AHAT system is available for use in recuperative or simple cycle system.
