Abstract

Abstract Translated from German Zu Betrieb einer Gas-Dampfturbinenanlage mit einer hohen Eintrittstemperatur der Gasturbinenanlage, wobei die im Heissgasstrom der Gasturbine befindlichen Teile dampfgekühlt werden und der dadurch weiter erhitzte Kühldampf zur weiteren Entspannung der Dampfturbine zugeleitet wird, wird vorgeschlagen, dass die Abgaswärme der Gasturbine (3) durch einen Zweidruck-Abhitzekessel (7) geleitet wird, und dass der darin erzeugte Dampf in einem Kühldampfüberhitzer (10) leicht überhitzt und den hohlen Leitschaufeln (43) und den ebenfalls hohlen Laufschaufeln (42) zugeführt wird, sich dabei stark überhitzt und anschliessend dem aus dem Zwischenüberhitzer (13) kommenden Dampf beigemischt und dem Niederdruckteil der Dampfturbine (27) zugeleitet wird. To operate a gas-steam turbine system with a high inlet temperature of the gas turbine system, the parts located in the hot gas stream of the gas turbine being steam-cooled and the cooling steam which is heated further thereby being supplied for further expansion of the steam turbine, it is proposed that the exhaust gas heat of the gas turbine (3) be generated by a Two-pressure waste heat boiler (7) is passed, and that the steam generated therein is slightly overheated in a cooling steam superheater (10) and fed to the hollow guide vanes (43) and the likewise hollow rotor blades (42), thereby overheating and then from the Intermediate superheater (13) coming steam is admixed and fed to the low-pressure part of the steam turbine (27).
