ABSTRACT:
Techniques suitable for recovering energy from a high-temperature gas of an ordinary pressure are provided. A turbomachine has a turbine16and compressors20and24. A combustor12is disposed at a stage above the turbine16. A power generating system generates power by passing a working fluid for the turbomachine through the combustor12, the turbine16and the compressors20and24in that order. An atmospheric pressure combustion turbine system includes: a regenerative heat exchanger14capable of cooling a high-temperature working gas discharged from the turbine16by 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; coolers22and26connected to the entrance of the compressors20and24, respectively, to cool the working gas by making the working gas exchange heat with water; and a humidifier30for producing a mixed gas by heating air by mixing part of the exhaust gas discharged from the compressor24in 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 exchanger14, the regenerative heat exchanger14produces 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 turbine16to heat the mixed gas, and the heated, high-temperature, humid, mixed gas is supplied to the combustor12.
