In a method for cooling thermally loaded components of a gas turbine group as part of a combined installation which, in addition, also consists of a waste heat steam generator and a steam cycle, a quantity of saturated steam is extracted from a drum of the steam cycle. The components mentioned, namely the combustion chamber and the turbine, are cooled in series by this saturated steam and the steam is subsequently returned to a steam turbine of the steam cycle at an appropriate location. The steam, from the steam turbine, employed for cooling is moderated, if required, with a proportion of water from the waste heat steam generator upstream of the components to be cooled.
