<p>PROBLEM TO BE SOLVED: To provide a Helmholtz damper for a combustor or burner of a gas turbine for a low-emission operation with high efficiency with regard to the thermoacoustic damping and sealing of components in the combustor.SOLUTION: A Helmholtz damper 10 for a combustor of a gas turbine includes an enclosure 11 defining a damping volume 11 from which a neck portion 2 extends and which has a flow path (F) for cooling and purging air with an inlet opening 6 and an outlet opening 3 to the enclosure 11. The outlet opening 3 is formed in the neck portion 2. A seal is arranged at the neck portion 2 adjacently to the outlet opening 3 for cooling and purging air such that a cooling effect of the seal is provided.</p> |
