ABSTRACT:
A burner includes a swirl generator (3) for a combustion airflow, has a conical swirl chamber (2) and a device for admitting fuel into the combustion airflow, wherein the swirl generator (3) incorporates combustion air inlet openings for the combustion airflow tangentially entering into the conical swirl chamber (2), and wherein the device for admitting fuel into the combustion airflow includes a first fuel feeding device having a first group (4) of fuel outlet openings substantially disposed in the direction of the burner axis for a first premix fuel quantity. The burner incorporates at least one second fuel feeding device having at least one second group (5) of fuel outlet openings that are substantially disposed in the direction of the burner axis for a second premix fuel quantity, which can be supplied with fuel independently from the first fuel feeding device, a burner lance (6) along a burner axis (A) projects from the side of the swirl chamber (2) with the smallest swirl chamber cross section into the swirl chamber (2), and the device for supplying fuel into the combustion airflow additionally incorporates at least one fuel outlet opening (8) within the burner lance (6), through which fuel is dischargeable along the burner axis.
