Abstract

In a gasifying oil burner with an oil atomizing device, with combustion air upply means surrounding the atomizing device, with a shield having a shield opening, said shield being disposed downstream of the outlet of the atomizer, with a mixing tube disposed downstream of the outlet of the atomizer, with a mixing tube disposed downsteam of an co-axial with the shield opening, with a radial passage at an upstream portion of the mixing tube, with a generally cylindric flame tube whose upstream end is sealingly connected to the end wall of the combustion air supply means carrying the shield, and wherein it is proposed that the mixing tube be provided with a solid wall at a section thereof adjoining the shield, that the radial passage adjoin a part of the mixing tube provided with the solid wall, and that the axial length of the mixing tube portion with the solid wall extending between the shield and the radial passage be between the 0.1-multiple and the 0.6-multiple of the inside diameter of the mixing tube, in order to provide a soot-free burning of heating oil having a very high content of aromatic hydrocarbons and/or a surplus of fuel in a recirculation region.
