The present invention relates to a burner with staged fuel injection, in which at least two separate stages (4a, 4b) for fuel injection are arranged along the swirl body (1). The burner is distinguished in that, between the first and the second stage (4a, 4b), a separating element (8) is provided, which extends in the direction of the combustion chamber (3) and separates the combustion air flow which enters in the region of the first stage (4a) from the combustion air flow which enters in the region of the second stage (4b). The proposed burner can be operated with low combustion pulsations even in the case of low burner powers.
