PURPOSE: To provide a secondary burner in which thermoacoustic vibration can be damped. CONSTITUTION: In a secondary burner where a fuel feed 2, 3 arranged in a combustion chamber 1 is surrounded by an annular air duct 4, the air duct 4 communicates, by means of at least one supply tube 5, with a through-flow Helmholtz resonator 6. The outlet from at least one damping tube 7 of the Helmholtz resonator is located in the region of the burner mouth 8 in a secondary combustion space 9. |
