Beschreibung
Zusammenfassung:	A steam-temperature control device for a gas- and steam turbine plant, including a feed water line, a feed-water control valve located in the feed water line and a water injection line which branches off from the feed water line upstream of the feed-water control valve in the flow direction of said water and which opens into an injection cooler is provided. The steam-temperature control device is characterized in that a pre-heating device for the injection water is connected in the water injection line. A method for controlling the steam temperature in a gas- and steam turbine plant is also provided.
