ABSTRACT:
In a method of operating a gas turbine installation in which the air prepared in a low-pressure compressor (1) is mixed with a fuel (4) downstream of the compression and is supplied to and burnt in a pressure-wave machine (3) operating with constant-volume or constant-pressure combustion and the working gas obtained in this manner is subsequently admitted to a high-pressure turbine (7) and a low-pressure turbine (8), there is an admixture of partially expanded and cooled gas from the high-pressure turbine (7) into the partial quantity flow led from the pressure-wave machine (3) to the low-pressure turbine (8). Fuel (4) is subsequently introduced and the mixture is burnt in a combustion chamber (9). A very high efficiency, very good part-load behavior and minimal NO.sub.x emission figures are achieved by means of this reheat.
