Abstract
In a burner of the double-cone design, bores (27) are arranged in the burner sickle (26), via which bores (27) the gaseous fuel (16), to the extent of about 3 to 8% of the total mass fuel flow, is mixed into the outer recirculation zone (28) of the burner. This leads to additional outer stabilization of the flame and to an extended operating range of the burner.
