PURPOSE:To improve the power generation efficiency by chemically converting the fuel to be supplied into a gas turbine into the secondary fuel having a high combustion energy by utilizing the waste heat energy discharged from the gas turbine. CONSTITUTION:In captioned system, fuel (a) with air (b) for combustion is combusted in a combustor 1, and a gas-turbine power generation system 2 is driven by utilizing the high-pressure combustion gas formed. Steam is formed in a waste heat boiler system 3 by the exhaust gas (c) discharged from the above- described power generation system 2, and a steam-turbine power generation system 4 is driven by said system, which is condensed into water in a condenser 5. A cracking reactor 7 constituted of a fuel preheating device and a fuel carburetor is installed in a flue in the above-described waste heat boiler system 3, and cracking (decomposition) reaction of fuel (a) is carried-out in said cracking reactor 7. Thus, the combustion energy of the fuel (a) is increased, and the power generation efficiency can be improved. |
