ABSTRACT:
In a gas turbine combustion chamber having an annular combustion space, the combustion chamber inlet is equipped with a plurality of burners, which are uniformly distributed in the peripheral direction and are fastened to a front plate. Scavenged Helmholtz resonators (21) consisting of supply tube (51), resonance volume (50) and damping tube (52) are arranged in the region of the burners. The damping tubes (52) are designed so as to be exchangeable, for which purpose the walls of the combustion space are provided with a manhole.
