Abstract

L'invention concerne une chambre de combustion (1) pour une installation de turbine à gaz, dotée d'une paroi (10) traversée par des gaz de combustion en direction d'une turbine à cycle d'expansion montée en aval. La paroi (10) de la chambre de combustion comporte un dispositif d'amortissement (20) destiné à amortir des vibrations thermoacoustiques provoquées par les gaz de combustion. Le dispositif d'amortissement (20) comprend au moins un résonateur de Helmholtz, réalisé de sorte que son volume (21) vienne se placer sur la face, de la paroi de chambre de combustion (10), opposée à une paroi intérieure de chambre de combustion (10') et comporte au moins un tube de résonateur (22) coopérant avec le volume de résonateur (21) et débouchant par son embouchure de tube de résonateur (M) opposée au volume de résonateur (21) dans la paroi intérieure de chambre de combustion (10') dans la chambre de combustion (1). Au moins une ouverture d'alimentation (23, 23', 23'') permet d'introduire dans la chambre de combustion (1) l'air de blocage destiné à bloquer l'embouchure de tube de résonateur (M) partant d'un plénum de compresseur (2) entourant la chambre de combustion, d'un compresseur pouvant être monté en aval. La ou les premières ouvertures d'alimentation (23', 23'') sont disposées dans une zone de la paroi de chambre de combustion (10) à proximité de l'embouchure de tube de résonateur (M) du ou des tubes de résonateurs (22) et sont orientées de sorte que l'air de blocage (S) circulant à travers l'ouverture d'alimentation (23', 23'') s'écoule dans l'embouchure de résonateur (M).
