Abstract
In a method of and an apparatus for operating a power station plant, essentially comprising a gas-turbine group (40, 41, 46), a waste-heat steam generator (8) and a downstream steam consumer, for example a steam turbine (1) having a generator (2), the exhaust gas of the gas-turbine group (40, 41, 46) releases heat to the water fed via a feed-water line (15) and directed in counterflow through the waste-heat steam generator (8). The steam generated is fed to the steam consumer (1) via at least one steam line (6). The water fed by the feed-water line (15) is directed through the waste-heat steam generator (8) in a once-through arrangement. The exhaust gases of the gas-turbine group (40, 41, 46) are directed through the waste-heat steam generator (8) at every operating instant. The steam generated in the waste-heat steam generator (8) is directed into the gas-turbine group (40, 41, 46) via an injection steam line (23) when the steam consumer (1) is shut off.
