Abstract (en)
[origin: DE19851636A1] Preferably for driving a gas turbo-group, the internal combustion engine burner incorporates a damping device for reduction of the vibration amplitude of acoustic waves. A mixture area (2) is provided for air and fuel and a combustion chamber (1) is arranged beyond the mixture area in which the fuel-air mixture is ignited. A Helmholz resonator (4) is directly connected with the mixture area. The acoustic waves formed in the burner are suppressed in the resonator and are not reflected back into the burner. The resonator is arranged in the flow direction of the fuel-air mixture before the mixture area.
