FIELD: fuel combustion methods and devices.
SUBSTANCE: system for damping the dynamic processes in the combustion chamber contains a micromixer having mixing tubes, an end cover assembly surrounding said mixing tubes and having a face plate and a reflective plate, and at least one annular resonator. Resonator is located inside the micro-mixer adjacent to the face plate and reflective plate and around the central fuel injector. Said at least one annular resonator has a first wall with apertures forming a system of openings at the low temperature side, a second wall with openings forming a system of openings on the high temperature side and a cavity substantially delimited by said first and second walls.
EFFECT: invention provides a uniform and effective damping of the dynamic processes in the combustion chamber.
