Abstract
Zur Dämpfung der tiefen Frequenzen in einem Abgassystem (10) für Industriegasturbinen mit einer Abgasleitung (12) und einem daran anschliessenden Kamin (14), welche zusammen einen durchgängigen Strömungskanal (16) bilden, wird ein Helmholtz-Resonator (24, 24', 24", 24a) mittels eines Absorptionsschalldämpfers (36) von der Strömung (S) akustisch transparent abgeschirmt am Strömungskanal (16) angeordnet. A Helmholtz resonator (24, 24 ', 24 ", 24a) by means of an absorption muffler (36) from the flow (S) in an acoustically transparent manner on the flow channel (16).
