Abstract

Zur Zwischenschaltung zwischen dem Ausgang einer Gasturbine und einen Dampferzeuger ist eine kombinierte Einrichtung vorgesehen, die sowohl als Schalldämpfer als auch als Diffusor wirkt und als Gasturbinenschalldämpfer bezeichnet wird. Der Gasturbinenschalldämpfer weist einen sich in Strömungsrichtung S mit einem relativ großen Winkel erweiternden Innenraum auf. In diesem sind Kulissenelemente angeordnet, die zwischeneinander Diffusorkanäle begrenzen, die sich jeweils mit einem wesentlich geringeren spitzen Winkel von unter 7° erweitern. Die engen Diffusorkanäle bewirken neben einer Verlangsamung der Gasströmung und somit neben einer Druckerhöhung zusätzlich eine Schalldämpfung durch Verminderung der Turbulenzen und einer Vergleichmäßigung und Ausrichtung der Strömung. Durch die Zusatzfunktion des Gasturbinenschalldämpfers als Diffusor können bisher erforderliche gesonderte Diffusoren, die einen großen Bauraum beansprucht haben, entfallen.
