PROBLEM TO BE SOLVED: To provide a gas turbine system suppressing the generation of white plume and to improve thermal efficiency. SOLUTION: This gas turbine system of this invention comprises an air compressor; a humidifying device to bring air compressed by the compressor into contact with water, a combustor to burn air humidified by the humidifying device and fuel; a gas turbine driven by combustion gas burnt in the combustor; a feed water heater heat exchanging between exhaust gas discharged from the gas turbine and water guided to the humidifying device; a water recovering apparatus to recover a moisture content from exhaust gas flowing through the feed water heater; and a heat exchanger heat exchanging between exhaust gas through the water recovering apparatus and compressed air from the compressor.
