Abstract
An oil burner comprises an oil conveying device, an air blower and a burner head, the burner head including a substantially cylindrical burner tube having an outlet orifice at one end, the burner tube tapering towards the orifice, a burner nozzle situated in the burner tube and having a plurality of supporting arms, and a baffle plate attached to and supported by the supporting arms of the burner nozzle. The burner nozzle is tapered towards an end of the outlet orifice of the burner tube to form a frustoconical end zone at the front end thereof. The baffle plate is of a cup shape and is arranged in the burner tube in front of the burner nozzle with the interior thereof pointing to the outlet orifice of the burner tube. The baffle plate includes a bottom zone conically widening towards the outlet orifice of the burner nozzle and having a central opening with a diameter equal to or larger than that of the burner nozzle, and an edge shell around the bottom zone widening towards the outlet orifice of the burner tube so that an annular gap is defined between a front end of the edge shell of the baffle plate and the inner face of the burner tube.
