ABSTRACT:
The invention relates to a stove which burns a primary combustible material in a container placed on a horizontal plate which divides the stove into upper and lower combustion chambers. The plate has a central aperture therethrough which, in operation, is in registry with a central opening in the container bottom wall. A hollow perforated tube is positioned in the container in registry with the opening and the aperture and the combustible material fills the container, surrounding the wall of the tube. When a temporary starting fire is lit in the lower chamber, the flames thereof will be drawn up into the tube and will light the combustible material in the container through the perforations in the tube. The combustible material in the container will burn radially outwardly from the tube in a uniform manner, with air circulation being provided in the expanding annular space between the tube and the burning face of the combustible material. Combustion may be controlled via appropriate air vents and ash will accumulate in the bottom of the container. The container may be removed so that the ashes may be conveniently disposed of and so that the container may be recharged with new combustible material.
