概要

A gas turbine system using high humidity air is thought to be suitable for a distributed power supply because of the simplicity of composition, high efficiency, and the applicability of co-generation. The concept of the humid air turbine (HAT cycle) was reported 20 years ago, but it has not been used commercially yet. In this paper, influence of the suction air atomization on performance, mass flow restriction by methods of humidifying compressed air, and the optimum conditions of humidity are clarified, and the system performance is calculated. The AHAT (Advanced HAT) system shows efficiency which is 5% higher compared with the mid-size combined cycle, and the increment grows, even further for a small-size machine. The overall cycle efficency of the co-generation system is 80%.
