PURPOSE:To reduce required pressurization of excessive air to reduce power required for the pressurization while improving heat recovering efficiency by recovering heat energy of exhaust gas with a system having water added or contacting water. CONSTITUTION:Air is sucked into a first stage AC1 of an air compressor through a suction pipe 3 and discharged from a discharge pipe 4 as intermediated pressurized gas. Pressurized water is preheated by an intermediate cooler 1C through a pipe 2 and injected into pressurized gas 7, intermediate pressurized gas 6 and pressurized gas fuel 1 through a pie 14, 15, 16, and 17 respectively. The gas having water injected is sucked into a second stage AC2 of the air compressor through a suction pipe 6, mixed with water from the pipe 16 through a discharge pipe 7 and introduced into a heat recoverer R1 through a pipe 8. Medium gas having recovered heat through the heat recoverer R1 is introduced into a combustor CC through a pipe 9 and combustion gas is introduced into an output turbine ET through a conduit 10.
