Abstract
A method for setting or regulating the steam temperature of the live steam and/or reheater steam, in particular under part load, in a combined-cycle power plant and a combined-cycle power plant so regulated. The power-plant has a water/steam cycle including a steam turbine, fired boiler and a means for superheating or reheating the steam generated in the boiler to form live steam or reheater steam, a gas turbine set, and a downstream heat recovery steam generator connected to the water/steam cycle in such a way that steam generated in the heat recovery steam generator is admixed with the live steam or reheater steam. Improved part-load behavior is achieved in that the steam temperature of the live steam and/or reheater steam is set or regulated by setting or regulating the steam temperature of the steam generated in the heat recovery steam generator.
