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.

Figure 00000001
A combined device is provided for the intermediate connection between the outlet of a gas turbine and a steam generator, which device acts both as a silencer and as a diffuser and is referred to as a gas turbine silencer. The gas turbine silencer has an interior that widens in the flow direction S with a relatively large angle. In this backdrop elements are arranged that delimit diffuser channels between each other, each widening with a much smaller acute angle of less than 7 °. In addition to slowing the gas flow and thus increasing the pressure, the narrow diffuser channels also result in sound absorption by reducing the turbulence and making the flow more even and aligned. Due to the additional function of the gas turbine muffler as a diffuser, previously required separate diffusers that have taken up a large installation space can be dispensed with.
