Gas turbine combustion chamber head with cooling and damping

摘要

The head has an annular combustion chamber inner wall, and burners distributed around circumference. An inflow-side wall (13) and a wall facing a combustion chamber form a combustion chamber head volume (15). The inflow-side wall comprises an inflow opening (32), and the wall facing the combustion chamber comprises an outflow opening (17) i.e. damping opening, connecting the combustion chamber head volume to the combustion chamber. A cooling air duct (29) is provided in the wall facing the combustion chamber. An independent claim is also included for a method for cooling and damping a combustion chamber head of a gas turbine.
