  • Method for operating a gas and steam turbine plant and gas and steam turbine plant operating according to the method
    Patent number: 5404708
    Abstract: A method for operating a gas and steam turbine plant includes producing steam for a steam turbine by utilizing heat contained in pressure-relieved flue gas of a gas turbine, and decreasing the temperature of the pressure-relieved flue gas upon the onset of a critical operating state, by introducing water into the pressure-relieved flue gas. A gas and steam turbine plant includes a gas turbine having a flue gas conduit, a steam turbine having a water-steam loop, a steam generator being connected to the flue gas conduit downstream of the gas turbine for producing steam in the water-steam loop, and a device for introducing water into the flue gas conduit.
