    Abstract: An object of the present invention is to provide a gas turbine for power generation operated at a turbine nozzle inlet temperature ranging from 1200 to 1650null C., which is improved to obtain a high heat efficiency by making disk blades and nozzles arranged in first to final stages from optimum materials and optimally cooling these disk blades and nozzles, and a combined power generation system using the gas turbine. The present invention provides a combined power generation system including a highly efficient gas turbine operated at a turbine nozzle inlet combustion gas temperature ranging from 1200 to 1650null C., and a high pressure-intermediate pressure-low pressure integral type steam turbine operated at a steam inlet temperature of 530null C. or more, wherein the gas turbine is configured such that turbine blades, nozzles and disks are each cooled, and the blades and nozzles are each made from an Ni-based alloy having a single crystal or columnar crystal structure and disks are made from a martensite steel.
