ABSTRACT:
Apparatus constructed to burn solid fuel within a firebox. The apparatus includes a burner having a receptacle and a jacket forming an air chamber about the receptacle. A fuel-feed conduit and an air-supply tube mounted adjacent the conduit for exchanging heat therewith are adapted to extend into the firebox. The burner is detachably mounted on the conduit and tube, in cantilever fashion within the firebox, through a port communicating with the air chamber and a duct communicating with the lower interior portion of the receptacle, respectively. Forced air supplied to the air chamber through the tube is vented into the upper region of the receptacle to support combustion of fuel supplied to the receptacle through the conduit and duct. The jacket's upper side wall inclines outwardly on progressing downwardly from the receptacle's upper opening to divert spill-over ash and clinker material away from the receptacle.
