Device and method to attenuate thermo-acoustic resonance in combustion chambers

摘要

The device has a combustion chamber (2) and a partial hollow cylindrical coaxial element (3) connected to the combustion chamber. Nozzle bores (10, 10a, 10b, 10c) are provided which are separated from each other and which a fluid flows and dissipates during the combustion of arising oscillation energy and an open jet (12) with a radial component into the combustion chamber (2). An independent claim is included for a method.
