ABSTRACT:
The present invention relates to a method and a device (1) for affecting thermoacoustic oscillations in a combustion system (6) comprising at least one burner (7) and at least one combustor (8).In order to improve the action of affecting the thermoacoustic oscillations,a gas flow forming in the e region of the burner (7) is excited acoustically,modulated injection of fuel is carried out,the acoustic excitation of the gas flow and the modulated injection of the fuel are coordinated in order to affect the same interference frequency.
