The gas turbine comprises a compressor for compressing combustion air, a burner for generating combustion gas, stationary blades for leading the combustion gas in a predetermined direction and a rotor having blades driven by the combustion gas. The steam turbine being provided with a high temperature and high pressure turbine portion, a medium pressure portion into which interheated steam from the high pressure portion is introduced with a high temperature and a medium pressure, and a low pressure portion into which steam from the medium pressure portion is introduced. Further the rotor of this steam turbine is provided with an integrated rotor shaft (3), blades (4) fixed on the rotor shaft in a multistage order from the high pressure side to the low pressure side of the steam, bearings (12) supporting the high and low pressure portions of the rotor, and a casing covering the rotor. The rotor of the steam turbine is designed for a temperature of at least 530 °C at the steam inlet stage blades and the length of the rotor blades (4) at the final stage in the low pressure side of the steam turbine are at least 762 mm.
