    摘要: An apparatus for damping acoustic vibrations in a combustor as well as a corresponding combustor arrangement with the apparatus. The apparatus includes a Helmholtz resonator (4) that can be connected via a connecting channel (2) with a combustor (1). The Helmholtz resonator (4) contains a hollow body (6) the volume of which can be changed by adding or draining a fluid via a supply line (5), or is located adjacent to such a hollow body in such a way that the resonance volume (3) of the Helmholtz resonator (4) is changed when the volume of the hollow body (6) is changed. This apparatus makes it possible to adjust the resonance frequency of a Helmholtz resonator arranged inside a pressure container in accordance with the respective current operating point of the combustor to be damped, without having to pass movable components through the pressure container.

    摘要: In a combustion chamber, the hot gases are prepared sequentially via two stages (20, 40). Arranged at the end of the first stage (20) in the direction of flow is a cross-sectional constriction (30) via which the hot gases (21) prepared in the first stage (20) are passed over into the second stage (40). The Mach number at the outlet (31) of this cross-sectional constriction (30) corresponds to the area ratio of outlet area (A2) over inlet area (A1). This results in a low-reflection configuration in which low-frequency vibrations are absorbed to a significant extent. And acoustic energy reflected from the turbine is substantially reduced.
