Abstract

In a combustion device (10), particularly for driving gas turbines, comprising a plurality of burners (12, . . . , 15) of identical thermal power output, which work parallel to an axis (28) into a common combustion chamber (11), an effective suppression of thermoacoustic combustion instabilities is achieved in a simple way in that the burners (12, . . . , 15) are designed differently from one another in such a way that the flames (24, . . . , 27) or flame fronts generated by them are positioned so as to be distributed along the axis (28).
