ABSTRACT:
The flame cone of the present invention is intended to be used with a heater for a grain bin or the like. The heater comprises a housing having one or more housing walls and having an inlet end and an outlet end. A blower is provided for forcefully moving air from the inlet end through the housing and out of the outlet end. A burner is provided within the housing for heating air moving through the housing. A flame diverter is positioned within the housing downstream from the burner for diverting the flame outwardly from the burner toward the walls of the housing. The diverter comprises a cone-shaped structure having a plurality of spaced slats diverging outwardly from the burner and toward the walls of the housing. More specifically, the improvement of this invention comprises a burner cone having an apex and an outer base spaced axially from the apex with the slope of the burner cone being generally similar to the slope of the diverter. The apex of the burner cone is positioned proximate the burner on the inside thereof so that there is a gap between the inside faces of the diverter slats and the outer surface of the burner cone so as to provide a path for the burning fuel to travel from the burner outwardly toward the housing walls thereby to result in more efficient combustion of the fuel.
