  • Gas and steam turbine plant and method for cooling a coolant of a gas turbine of such a plant
    Patent number: 6405520
    Abstract: A gas and steam-turbine plant includes a waste-heat steam generator connected downstream of a gas turbine on the flue-gas side. The waste-heat steam generator has heating areas connected in a water/steam circuit of a steam turbine. A heat exchanger is provided for cooling a coolant of the gas turbine in order to ensure reliable cooling of the gas turbine even under varied operating conditions. The heat exchanger has a secondary side connected in a second water/steam circuit. The second water/steam circuit is connected to the water/steam circuit of the steam turbine in such a way that it can be shut off. A method is also provided for cooling a coolant of a gas turbine of a gas and steam-turbine plant.
