OIL GASIFYING BURNER WITH AN OIL ATOMIZING DEVICE

摘要

A GASIFIED OIL BURNER WITH OIL ATOMIZER A gasified oil burner with an oil atomizing device surrounded by combustion air supply means whose downstream end if formed by a shield having a shield opening disposed downstream of the outlet of the atomizer. A mixing tube is disposed downstream of the outlet of the atomizer. It is co-axial with the shield opening. A radial passage is arranged at an upstream portion of the mixing tube. A generally cylindric flame tube whose upstream end is sealingly connected to the end wall of the combustion air supply means is integral with the shield. The mixing tube is provided with a solid wall part at a section thereof adjoining the shield. The radial passage adjoins a part of the mixing tube provided with the solid wall part. The axial length of the mixing tube portion with the solid wall extending between the shield and the radial passage is between the 0.1-multiple and the 0.6-multiple of the inside diameter of the mixing tube at that part of the mixing tube which is located downstream of the radial passage. The invention improves the feature of soot-free burning of heating oil having a very high content of aromatic hydrocarbons and/or a surplus of fuel in a recirculation of the burner.
