ABSTRACT:
A burning device includes a plurality of interconnected chamber walls defining a burning chamber and a central axis, each chamber wall also defining a plurality of chamber apertures. A plurality of flanges extend radially from the chamber walls and substantially parallel to the central axis, and a plurality of circumferentially extending lips extending from a respective flange. Each lip is radially spaced apart from an associated chamber wall and defines therebetween an air flow passageway communicating with the burning chamber and affording air flow into the burning chamber. Ventilation apertures are defined in at least one of the plurality of lips and the plurality of flanges, the ventilation apertures providing communication between the air flow passageways and the burning chamber. A cover is removably supported by the chamber walls and defines a plurality of apertures.
