DAMPER FOR GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To provide a damper for a gas turbine combustion chamber that allows independent thermal movement in components without causing structural stress.SOLUTION: A damper 1 for a gas turbine combustion chamber has a damper volume wall part 3 and a main neck. The damper volume wall part 3 defines a damper volume 2 inside the damper volume wall part 3. The main neck has a main neck wall part 4 defining a main neck volume 5 inside the main neck wall part 4. The main neck is associated with the damper volume 2 for fluid connection between the damper volume 2 and a gas turbine combustion chamber 6. In addition, the damper has a second neck of a gap 7 between the main neck wall part 4 and the damper volume wall part 3.SELECTED DRAWING: Figure 1
