PURPOSE:To effectively utilize the high-quality, high-temperature exhaust heat and the unreacted fuel by burning the high-temperature, high-pressure exhaust air and exhaust fuel from a solid electrolyte fuel cell, driving a compressor and a generator via an expansion turbine introduced with the high-temperature, high- pressure combustion gas after combustion, generating vapor via the exhaust gas at the expansion turbine outlet, and driving a steam turbine. CONSTITUTION:The high-temperature, high-pressure air from a compressor is fed to an air preheater 43. The high-temperature, high-pressure air from the preheater 43 is fed to a solid electrolyte fuel cell cathode 40. Fuel 59 is preheated 60 by a fuel preheater 47 by using the exhaust gas 57 from an expansion turbine 45 and is fed to a solid electrolyte fuel cell anode 41. In the solid electrolyte fuel cell, the fuel from the anode is reacted with oxygen ions moved from the cathode through the solid electrolyte 42, thus causing the movement of electrons. The exhaust fuel 61 from the anode outlet and the exhaust air 55 from the cathode outlet are guided into an auxiliary combustor 44 for combustion. The combustion gas 56 from the auxiliary combustor 44 drives the expansion turbine 45. The combustion turbine 45 drives an air compressor 39 and a generator 46. |
