Benninghoven, E

A burner is disclosed for alternatively burning coal dust or oil. An annular housing includes a blower at one end thereof for directing a rotating air stream through the housing. A chamber located downstream from the blower has a plurality of outlet pipes extending downstream therefrom in an annular configuration about an atomizing nozzle and an eddy plate. An adjustable burner head is mounted on the end of each of the outlet pipes, the burner heads being arranged for optimum mixture of coal dust and air, fed from the chamber through the outlet pipes to the burner heads, with the rotating air stream passing about and through a hole in the eddy plate to insure optimum combustion. An oil ignition auxiliary burner having a nozzle between the eddy plate and the outlet end of the chamber serves to ignite the coal dust and air mixture. An atomizing nozzle for feeding atomized oil into the burner is provided as an alternative fuel source.
