Ambient temperature effects, performance of WAC (Water Atomization Cooling), part-load characteristics and start-up characteristics of the AHAT (Advanced Humid Air Turbine) system were studied both experimentally and analytically. Ambient temperature effects and part-load characteristics of the 3MW AHAT pilot plant were measured and they were compared with heat and material balance calculation results. Then, these characteristics of the AHAT and the combined cycle, which were composed of mid-sized industrial gas turbines, were calculated. Results of WAC operation showed that it can not only decrease compressor power but also increase air flow rate and pressure ratio of the compressor, which leads considerable augmentation of power and thermal efficiency of the AHAT. The cold start-up time of the 3MW AHAT pilot plant was about 60 minutes, which was governed by the heat capacities of the plant equipments.
