Patent Images
1. A gas-turbine combustion chamber wall for a lean-burning gas-turbine combustion chamber, comprising:
- a combustion chamber casing;
several combustion chamber segments arranged in the combustion chamber casing and forming a combustion chamber wall, each of the combustion chamber segments being supplied with cooling air with film cooling via at least one of axial cooling holes and radial cooling holes, with the cooling holes being axially spaced from each other; and
dampening openings being provided in the combustion chamber wall for the introduction of air;
wherein the combustion chamber segments are of a double-wall design and at least one includes a damper casing arranged radially outward and forming a circumferential dampening volume;
wherein one end of the damper casing is firmly attached to the combustion chamber segment and an other end is slideably connected to the combustion chamber segment.
