The AHAT (Advanced HAT) system can be used for single shaft gas turbines without redesigning them and it gives a similar effect as intercooling by using suction air atomization. In this paper, two basic experiments with a spray nozzle, simplified humidifier and water recovery were carried out. A compact heat exchanger for humidified gas turbines could be realized by using the spray nozzle without significant pressure loss. In addition, a big effect was found in the efficiency improvement when water atomization into the compressor was combined with the regenerative cycle. The AHAT system had high efficiency, 5% higher compared with the mid-size combined cycle.
