PROBLEM TO BE SOLVED: To provide a near-wall cooling system for a damping device of a gas turbine combustor with significantly reduced cooling air mass flow requirements.SOLUTION: An end plate 10 separating a damping volume 9 from a combustion chamber 3 is fixed to an inner wall 5. The end plate 10 is provided with a neck passage 13, and additionally provided with at least one feed plenum 12, 15 for a cooling medium, at least one exit plenum 16 for the cooling medium, and at least one cooling passage 14 enabling a flow of the cooling medium from at least one first feed plenum 12 to a second feed plenum 15 or to the at least one exit plenum 16. |
