Abstract: A support frame with legs is provided for supporting a chamber member with walls that taper inward from its upper end to an ash removal opening and a middle member forming a heating cavity. The upper end of the middle is adapted to support an upper member with walls that taper inward from its lower end to an upper vent. A lower grate is supported at the lower opening of the middle member for holding material to be burned. An upper grate is supported at the upper end of the middle member for supporting food to be cooked. In a further aspect, a side opening is formed through the wall of the middle member for use for adding burnable material on the lower grate. The four members can be broken down and stacked together in a small volume.
