摘要： The invention relates to a damper for reducing the pulsations in a chamber of a gas turbine. The damper includes a resonator cavity and a neck in flow communication with the resonator cavity and the chamber. The neck includes a mouth to communicate with the chamber. The air flow inside the chamber flows across the mouth of the neck. The neck is so configured that the longitudinal axis of its mouth is angled 0-90° relative to the direction of the air flow inside the chamber. The damper of this invention may effectively alleviate the detrimental effect of the grazing flow and thus it enables the placement of the damper also at locations where strong grazing flows are present.

The damping device includes a wall with a first inner wall and a second outer wall, arranged in a distance to each other. The inner wall is subjected to high temperatures on a side with a hot gas flow. A plurality of cooling channels extend essentially parallel between the first inner wall and the second outer wall, and at least one damping volume bordered by cooling channels. Furthermore, the damping device includes a first passage for supplying a cooling medium from a cooling channel into the damping volume and a second passage for connecting the damping volume to the combustion chamber.

摘要： A damping device for a gas turbine has at least one Helmholtz resonator and at least one duct, wherein the Helmholtz resonator has a resonator housing and at least one resonator neck pipe and the resonator housing encloses a resonance volume of the Helmholtz resonator, into which volume acoustic vibrations can be injected by means of the resonator neck pipe. The damping device enables a particularly effective damping of thermo-acoustic vibrations. For this purpose, the duct is formed with a duct jacket and at least one outlet opening. Acoustic vibrations of a fluid stream flowing through a burner plenum and a combustion chamber can be injected into the outlet opening. A cooling fluid can be applied to the duct and the at least one resonator neck pipe opens on the hot-gas side into such a duct upstream of the at least one outlet opening.
