Abstract
A combustible device which can be ignited to furnish warmth for comfort, heat for cooking, and light for illumination, and which may also be aesthetically pleasing. The device includes a shell formed of combustible material, which defines an updraft chamber, an intake chamber located at the lower portion of the updraft chamber and being in fluid communication with both the updraft chamber and the outside of the shell, and one or more exhaust flues located at the top of the updraft chamber. The flues also are in fluid communication with both the updraft chamber and the outside of the shell, to provide an exit for smoke and ashes formed by combustion in the updraft chamber. The updraft chamber may be tapered, so that the upper portion of the updraft chamber is narrower than the lower portion of the updraft chamber. Preferably, the combustible shell is formed with an aesthetically pleasing appearance, such as a relief shaped like a face. The shell may also include a thick, solid spine along its length, to maintain the balance of the shell while it burns.
