To enable a burnpot for a corn burning stove to be continuously operated, the burnpot has either: (1) an openable bottom with at least a first and second position, one of the at least first and second positions being substantially closed to enable a body of combustible fuel to burn on its upper surface, the other of the at least first and second positions providing an opening, burnpot side wall portions and a top of the burnpot being shaped so as to permit a solid clinker to drop out of the opening in the openable bottom when the openable bottom is in its second position; or (2) a bottom formed as one of a series of sections of a rotatable member so that as the member rotates, it carries ash with it away from the bottom of the burnpot. A combustion volume is provided between the openable bottom or rotatable bottom, the side surfaces and the top, the combustion volume having an upper portion and a lower portion whereby a fire on a combustion surface in the lower portion burns upwardly toward the upper portion so that byproducts of combustion build on the combustion surface to cause burning fuel to burn at a higher level; the higher level having a smaller cross sectional area than the lower portion whereby the byproducts of combustion may drop as a unit out of the burnpot bottom opening. Easy to ignite fuel is moved from one hopper into the burnpot and ignited. When the temperature is high enough to ignite the harder to ignite fuel it is moved into the burnpot and the flow of easy to ignite fuel stopped.
