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. To be interposed between the output of a gas turbine and a steam generator, a combined device is provided, which is referred to both as a silencer as well as a diffuser and acting as a gas turbine muffler. Der Gasturbinenschalldämpfer weist einen sich in Strömungsrichtung S mit einem relativ großen Winkel erweiternden Innenraum auf. The gas turbine muffler has a in the flow direction S at a relatively large angle widening inner space. In diesem sind Kulissenelemente angeordnet, die zwischeneinander Diffusorkanäle begrenzen, die sich jeweils mit einem wesentlich geringeren spitzen Winkel von unter 7° erweitern. In this setting elements are arranged which define therebetween diffuser channels which extend in each case with a much smaller acute angle of less than 7 °. 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. The narrow diffuser channels adjacent to cause a slowing of the gas flow and thus in addition to an increase in pressure in addition, a sound attenuation by reducing the turbulence and an equalization and orientation of the flow. Durch die Zusatzfunktion des Gasturbinenschalldämpfers als Diffusor können bisher erforderliche gesonderte Diffusoren, die einen großen Bauraum beansprucht haben, entfallen. Through the additional function of the gas turbine muffler as a diffuser may previously required separate diffusers which have requested a large amount of space, are eliminated.
