Abstract
In order to operate a gas turbine and steam turbine plant with a high temperature at the inlet to the gas turbine plant, the parts located in the hot-gas stream of the gas turbine being steam-cooled, and the cooling steam, thereby raised to a higher temperature, being fed to the steam turbine for further expansion, it is proposed that the waste heat from the gas turbine (3) be led through a two-pressure waste heat boiler (7), and that the steam, generated in this boiler, be slightly superheated in a cooling-steam superheater (10), and fed to the hollow inlet vanes (43) and to the rotor blades (42), which are likewise hollow, the steam, strongly superheated during this cooling process, then being admixed to the steam coming from the intermediate superheater (13), and being fed to the low-pressure section of the steam turbine (27).
