PURPOSE:To permit efficient power-generation and efficiently recover steam by installing a duct burning apparatus between a heat exchanger and an air turbine and further heating the high-temperature high-pressure air heated below the temperature at which the deterioration of high-temperature strength of the heat-exchanger material does not occur. CONSTITUTION:Fuel is supplied into a combustor 10 from a pipe 11, and combustion is carried-out by supplying air through the pipe 62 connected to an air turbine 60. While combustion gas is introduced into a heat exchanger 20 and heats the high-pressure air in a heat transmitting tube 21. The heated air is sent into a duct burning apparatus 40 through the primary high-temperature and high- pressure air pipe 53, and heated by a duct burner 41, and then introduced into the turbine 60 through the secondary high-temperature high-pressure air pipe 54, and generation is performed. The exhaust gas supplied from the turbine 60 is sent into the combustor 10 through a pipe 62. In a steam recovering device 30, the water introduced from a pipe 31 is heated by the combustion gas introduced from a pipe 22, and converted to steam, and said steam is recovered from a taking-out pipe 32. |
