1. A heater assembly comprising an outer housing having an inlet end and an outlet end, the outer housing having one or more housing walls, a blower for forcefully moving air from the inlet end through the outer housing and out of the outlet end, a burner within the outer housing intermediate the inlet and outlet ends for burning a fuel within the outer housing and for heating the air moving through the housing, the burner comprising:
a collector adapted to receive fuel from a fuel line; a burner housing attached to the collector to receive fuel; a nozzle attached to the burner housing to receive fuel, the nozzle comprising a member having a surface with a plurality of holes defined therein, said nozzle further having a plurality of elongate conduits extending from the surface of the nozzle, each of said plurality of conduits in fluidic communication with one of said plurality holes in the surface, the conduit defining outlets for the fuel; a flame diverter within the outer housing downstream from the nozzle sized, shaped and adapted to divert the flame outwardly from the nozzle toward the walls of the outer housing, the flame diverter comprising a cone-shaped member diverging outwardly from the nozzle and toward the walls of the outer housing, the diverter defining a plurality of spaced openings through which air moved by the blower may pass; and a flame cone having an apex and an outer base spaced axially from the apex with the slope of the flame cone being generally similar to the slope of the flame diverter, the apex of the flame cone being positioned near the nozzle on the inside of the flame diverter to define a gap between the inside face of the flame diverter and the outer surface of the flame cone; said gap defining a path for burning fuel to travel from the nozzle outwardly toward the outer housing wall, thereby to result in substantially complete combustion of the fuel. |
