Abstract (en)
[origin: EP0778445A2] The two part-conical bodies (12,13) interfit in the flow direction. The cone axes are staggered in relation to the centre axis (10) and form tangential slits (16) for the combustion air (9). A feeder lance (1) extending downstream into the interior of the pre-mixing burner (11) from the tip of the part-conical bodies runs symmetrically in relation to the centre axis. At least one fuel nozzle is situated on the end of the feeder lance away from the flow. The lance consists of a tube (2) containing a fuel pipe in which is an inner fuel inlet duct and an outer fuel inflow duct.
