Abstract
The invention relating to a A damper for combustion oscillation damping for a gas turbine, includes a resonator cavity with a box or cylinder shape, a neck in flow communication with the resonator cavity and a combustion chamber. The length Lof the neck is equal or greater than a maximum distance lthat a hot gas ingested from the combustion chamber reaches in the neck. The maximum distance lis determined according to the following equation: With the solution of the present invention, the damper used to damping combustion oscillation may prevent hot gas ingestion during normal operations by uniquely determining the dimensions of the neck connecting the resonator cavity and the combustion chamber.
