Abstract
In a method for operating a gas turbine group (32) having an integrated steam process (33) and having an air storage installation (34), a partial mass flow (17) is extracted from a high-pressure turbine (15) of the gas turbine group (32) and passed through a heat exchanger (20) for cooling one or a plurality of structures of the gas turbine group (32). This heat exchanger (20) is operated by a cooler medium (4, 6). The partial mass flow (17) cooled in this way is subsequently passed through the structures (18, 19) to be cooled of the gas turbine group (32). By this means, the cooling is achieved of, in particular, the structures installed downstream of the high-pressure turbine (15). The heat generator (18) connected downstream and the low-pressure turbine (19) can be connected in parallel or in series. It is therefore possible to achieve cooling of the loaded structures of the gas turbine group (32) without, in the process, affecting the working gas balance of the installation.
