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. An air-supply conduit and a fuel conduit disposed concentrically therein are adapted to extend into the firebox. The burner is detachably mounted on the two conduits in cantilever fashion within the firebox, to communicate the air and fuel conduits with the jacket and 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 fuel conduit.
