Method and device for flame stabilization in a burner system of a stationary combustion engine

A method for flame stabilization in a burner system of a stationary combustion engine, the method comprising:

• producing a flow of an air/fuel mixture;
• swirling the flow to form a vortex flow to which a swirl number is assignable before the vortex flow enters a combustion zone;
• igniting the vortex flow of the air/fuel mixture to form a flame within a reverse flow zone caused by vortex breakdown;
• and
• controlling a swirl number perturbation driven by thermoacoustic oscillation inside the burner system by affecting the vortex flow actively before the flow enters the combustion zone on basis of changing a flame transfer function assigned to the burner system with a proviso of reducing pulsation amplitudes of the flame transfer function, wherein the pulsation amplitudes are associated with a change in amplitude of flame oscillation, wherein actively affecting the vortex flow includes harmonically modulating a shape or position of a swirler by frictionless magnetic levitation using an electromagnetic field acting on the swirler.
