DAMPING DEVICE FOR A GAS TURBINE, GAS TURBINE AND METHOD FOR DAMPING THERMO-ACOUSTIC VIBRATIONS |
摘要 |
<p>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.</p> |
