In the case of a burner, essentially consisting of a swirl generator (9) for a combustion air flow (22, 23), a swirl chamber (26) and means (1-8, 11-18, 24, 25) for introducing combustion flow into the combustion air flow ( 22, 23), the swirl generator (9) having inlet slots (30, 31) for the combustion air flow (22, 23) entering tangentially into the swirl chamber (26) and the means for introducing fuel into the combustion air flow at least one fuel feed (24) with fuel outlet openings (32) arranged essentially in the direction of a burner axis (28), the possibility of reducing pulsations and / or nitrogen oxide emissions during operation is made possible by dividing the fuel outlet openings (32) into at least three groups, and the fuel mass flow of the groups can be regulated independently of one another via valves (1-8, 11-18). |
