A combined gas-turbine and steam-turbine plant includes waste-heat steam generator which is located downstream of the gas turbine. The heating surfaces of the waste-heat steam generator are connected in a water/steam loop of the steam turbine. The gas turbine is cooled and the heat obtained in that heat exchange is further utilized. An intermediate circuit is linked to a first heat exchanger which cools the coolant of the gas turbine and to a second heat exchanger which is connected in the water/steam loop.
