Provided is turbine plant using methanol as fuel by which gross thermal efficiency of combined cycle power plant using combustion gas generated by combustion of H2 and CO2 plus O2 as working fluid is enhanced. Working fluid is compressed by compressor 1 and led into combustor 2. Mixture of H2 and CO2 as fuel added with O2 is burned to generate high temperature gas, which works at high temperature turbine 3, flows through heat exchangers 4, 5 and returns partly to the compressor 1 and enters partly low pressure turbine 7 of bottoming system to work. Condensed water from condenser 9 of the bottoming system is pressurized by pressure pump 10 and flows through the heat exchangers 4, to become high temperature steam and to work at high pressure turbine 6. Exhaust gas thereof is mixed into the combustor 2. Mixture of methanol and water is supplied into reformer 13 to absorb heat from the heat exchanger 4 to be reformed into H2 and CO2, which is supplied into the combustor 2. Thereby, gross thermal efficiency is enhanced. High temperature portion of the high temperature turbine 3 is cooled by cooling medium extracted from compressor 1 outlet anti high pressure turbine 6 outlet, thereby reliability of the high temperature turbine 3 is enhanced.
