Techniques suitable for recovering energy from a high-temperature gas of an ordinary pressure are provided. A turbomachine has a turbineand compressorsand. A combustoris disposed at a stage above the turbine. A power generating system generates power by passing a working fluid for the turbomachine through the combustor, the turbineand the compressorsandin that order. An atmospheric pressure combustion turbine system includes: a regenerative heat exchangercapable of cooling a high-temperature working gas discharged from the turbineby making the high-temperature working gas exchange heat with a mixed gas produced by mixing an exhaust gas and air and moistened with hot water; coolersandconnected to the entrance of the compressorsand, respectively, to cool the working gas by making the working gas exchange heat with water; and a humidifierfor producing a mixed gas by heating air by mixing part of the exhaust gas discharged from the compressorin the air and humidifying the heated air with the hot water produced by heating water by the heat of the working gas through heat exchange. The mixed gas produced by the humidifier is supplied to the regenerative heat exchanger, the regenerative heat exchangerproduces a high-temperature, humid, mixed gas by making the mixed gas exchange heat with the high-temperature working gas discharged through the exit of the turbineto heat the mixed gas, and the heated, high-temperature, humid, mixed gas is supplied to the combustor
