Gas turbine combustion chamber with scavenged Helmholtz resonators

A gas turbine combustion chamber for a stationary power plant, comprising:

• a radial inner wall and a radial outer wall an annular combustion space, the walls extending in an axial direction from a combustion chamber inlet to an inlet to a gas turbine;
• a front plate at the combustion chamber inlet;
• a plurality of burners mounted on the front plate and evenly distributed in a peripheral direction of the combustion chamber inlet;
• and,
• a plurality of scavenged Helmholtz dampers for damping thermoacoustic vibrations mounted in proximity to the burners, each Helmholtz damper comprising a resonance volume, a supply tube connecting the resonance volume to a compressed air supply duct, and damping tube connecting the resonance volume to the combustion space, the damping tube permitting a predetermined quantity of air to flow to the combustion space for cooling the resonating chamber.
