Abstract (en)
[origin: EP1429003A2] A flow of gas (FOG) near a burner (7) is subjected to acoustic stimulation. This modulates the injection of fuel. The acoustic stimulation of the FOG and the modulated fuel injection are tuned to the affects from the same interference frequency. A measured signal is subjected to a first phase shift to generate a first driver signal that triggers an acoustic source (3) to stimulate the FOG. An Independent claim is also included for a device for affecting thermoacoustic vibrations in a combustion system.
