<P>PROBLEM TO BE SOLVED: To provide a combined power generation plant capable of further increasing power output and enhancing system efficiency. <P>SOLUTION: In the combined power generation plant, an exhaust heat recovery boiler 16 exchanging heat of a working fluid which is supplied to a steam turbine 14 to rotationally drive the steam turbine 14 and generates gas at a temperature lower than the boiling point of water circulating in a Kalina cycle or changes the phase with a combustion gas 21 introduced from a gas turbine 11 and generating saturated steam 44 by heat taken from the combustion gas 21, a gas/liquid separator 45 separating the saturated steam 44 flowing out from the heat recovery boiler 16 into gas 46 and liquid 47, and a superheater 17 exchanging heat of the gas 46 separated by the gas/liquid separator 45 with compressed air 25 compressed by a compressor 31 rotationally driven by the gas turbine 11 and generating superheated steam 41 by heat drawn from the compressed air 25, are provided on the upstream side of the steam turbine 14. <P>COPYRIGHT: (C)2013,JPO&INPIT |
