Appl. No.:

7/579853

International Classification:

F23C 506

US Classification:

431189

Abstract:

A gun-type oil burner is disclosed having a motor axially aligned with a fuel pump and a blower at opposite ends. The blower draws air into the burner, the amount of which is controlled by an adjustable air gate. The blower inlet is covered by a removable, protective air scoop. Upon removal of the air scoop, an outside air boot is easily connected to the burner without burner modification. The air in the burner travels along a serpentine path which contains smooth curves and perimetrally disposed protrusions for reducing the velocity of the air flow and maintaining its static pressure. The air flows through an air tube in a helical pattern, mixes with oil and is ignited at the air tube outlet. A fuel nozzle, ignitors and a fuel supply conduit are supported as a burner sub-assembly within the tube by a spider. A preselected stop of a number of removable stops of differing sizes is located on the spider and properly positions the burner sub-assembly within the air tube.
