Abstract
In a method of 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 (30), the exhaust gas from the gas-turbine group (40, 41, 46) releases heat to the water conducted in counterflow through the waste-heat steam generator (8), and the steam produced is fed to the steam consumer (30) via at least one steam line (6). The water is at any temperature and is fed directly into the waste-heat steam generator (8) via at least one water line (11) having an allocated regulating valve (20) for limiting the flow. During the use of fuels having sulfur contents, the regulating valve (20) is controlled via the temperature of the exhaust gas at the discharge from the waste-heat steam generator (8), at a temperature measuring device (24).
