ABSTRACT:
The present invention relates to a method and a device for affecting thermoacoustic oscillations in a combustion system (i) comprising at least one burner (2) and at least one combustor (3), modulated injection of fuel being carried out. In order to improve the action of affecting the thermoacoustic oscillations, the modulated injection of the fuel is carried out into a recirculation zone (7) which forms in the combustor (3).
