Abstract (en)
The combustion chamber (12) has a resonator device for absorbing thermal acoustic oscillations inside the chamber. The resonator has a resonator volume (24) connecting through an opening (26) with the inside of the chamber. An oscillation activator (32) energizes an oscillation in the resonator volume. An independent claim is included for a method of suppressing combustion vibrations, and a gas turbine system.
