GAS TURBINE COMBINED CYCLE POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To amplify both enthalpy and exergy and reduce the exergy loss in combustion process by connecting a steam reforming system of fuel to a combustor. SOLUTION: A combustor is connected to an air compressor, and a gas turbine is connected to the combustor to connect a methanol steam reforming reactor to the combustor through the gas turbine. A part of the exhaust steam 12 of a high-pressure steam turbine is supplied to the steam reforming reactor together with methanol, and a reaction heat is also supplied by use of the heat of the exhaust gas 6 of the gas turbine. The steam reforming reactor converts all the methanol is converted to hydrogen and carbon dioxide at about 250 deg.C in the steam reforming reactor, and the methanol steam reformed gas is mixed with natural gas in a mixer and then supplied to the combustor to provide a combustion gas of 1450 deg.C or higher.
