PROBLEM TO BE SOLVED: To solve the informed problem in relation to compound generation of a gas turbine and a fuel battery that inlet temperature of an expansion turbine, serving as operation temperature of the fuel battery, is lower than the inlet temperature of the expansion turbine in a simple cycle gas turbine. SOLUTION: An expansion turbine is divided. A burner for directly burning fuel is arranged on a front stage side inlet of the divided turbine, while a fuel battery is arranged on a rear stage side inlet. A burning means is arranged for burning combustible components in the fuel in exhaust gas from the fuel battery. A regenerator has a heating means for simultaneously heating air discharged from a gas turbine compressor by utilizing quantity of heat of the exhaust gas from the rear stage side turbine, and a means for supplying the heated fuel while distributing it into the burner and the fuel battery. |
