<p>PROBLEM TO BE SOLVED: To provide a gas turbine-combined cycle power generation system capable of eliminating NOx in an exhaust gas with high efficiency to easily introduce GTCC, to significantly save water by effectively utilizing condensate water recovered from the exhaust gas in a condensate cooling system of a steam turbine and the like, and to improve power generation efficiency as a whole and to ease and prevent heat island by recovering latent heat by condensate afterheat, simultaneously with recovering of the condensate water.SOLUTION: An exhaust heat recovering device 5 having an exhaust heat recovering coil 14, a denitrification device 15, a latent heat recovering device 6 having a latent heat recovering coil 17, and a condensate water recovering unit 8 connected to the latent heat recovering device 6, are disposed in an exhaust gas passage of a gas turbine. The condensate water of the condensate water recovering unit 8 is supplied to a condensate cooling system of a steam turbine 2.</p> |
