  • Patent number: 9719676
    Abstract: A power plant, particularly a coupled gas and steam power plant, including a plurality of first drainage lines that are fluidically connected on the upstream side to a water-steam circuit and are fluidically connected on the downstream side to an overpressure vessel, is provided. Additionally, at least one steam-conducting supply line, via which steam can be fed back to the water-steam circuit, is fluidically connected to the overpressure vessel. A method for operating such a power plant, wherein the at least one steam-conducting supply line can supply steam to the water-steam circuit in the region of a low-pressure stage, particularly in the region of the steam drum of the low-pressure stage is also provided.
    Type: Grant
    Filed: December 3, 2013
    Date of Patent: August 1, 2017
