Abstract
A method for flushing a heat recovery steam generator in a power plant having a gas turbine, having a compressor, a combustion chamber and a turbine with a rotor, and having a generator coupled to the gas turbine and a start-up converter to convert from an alternating current of random frequency into an alternating current of a specified frequency. The start-up converter is connected to an output of the generator at which the alternating current of random frequency is applied. Wherein, when the gas turbine is run down, the rotor is cushioned with the help of the start-up converter at a boiler flushing speed and the heat recovery steam generator is further flushed until the specifications for flushing the waste heat steam generator are complied with.
