Abstract
A burner for operating a heat generator includes a rotation generator (100) for a combustion air stream (115), a device for injecting at least one fuel (112, 116) into the combustion air stream, a number of transition channels (201) for transferring a flow formed in the rotation generator into a mixing pipe (20) located downstream from these transition channels, and a pilot burner system (300) in the lower part of the mixing pipe (20), in which the pilot burner system (300) is in active connection with rotation generators (400) located at the end side of the mixing pipe (20). The interaction between the pilot burner system and rotation generators ensures maximized flame stability in the combustion chamber (30), and a general minimization of pollutant emissions, while increasing the load range for lower pollutants towards smaller loads.
