Abstract:
1. An apparatus for burning solid fuel comprising: a body having an interior; a solid fuel supply chamber connected to said body; a feed mechanism extending between said solid fuel supply chamber and said interior of said body, said feed mechanism suitable for carrying the solid fuel from said solid fuel supply chamber toward a combustion region within said interior of said body; a main burning block having an air and fuel cell connected to said solid fuel supply chamber, said main burning block having a plurality of air outlet vents formed on an external wall surface thereof; a preventive surface positioned at a distance over said external wall surface of said main burning block so as to form a closed volume; and at least one fuel discharge outlet suitable for allowing the solid fuel to pass therethrough to said external wall surface of said main burning block, said external wall surface having radiused surfaces, the at least one fuel discharge outlet having conical surfaces and oval surfaces so as to provide for an expansion of the fuel, said external wall surface being circular and swaged; a plurality of inverse spiral wings which correspond to a plurality of spiral wings formed on a shaft of said feed mechanism so as to face each other; at least one push component suitable for pushing the solid fuel toward the fuel discharge outlet via said plurality of spiral wings and said plurality of inverse spiral wings, said shaft causing said plurality of spiral wings and said plurality of inverse spiral wings to rotate; a fuel spreader and mixer comprising a drive component and a drive shaft and a mixer lever, said drive shaft and said drive component causing a rotating motion of said mixer lever so as to cause homogenous spreading of the fuel on said radiused surfaces after said push component pushes the solid fuel toward said fuel discharge outlet; a plurality of contact footings connected to said mixer lever so as to homogenously spread the solid fuel; an impact surface formed on said preventive surface so as to prevent volatilization of volatile gases; a plurality of positioning feet formed integrally with said impact surface; a plurality of load-bearing feet upon which said plurality of positioning feet are positioned; and a combustion cell formed by the positioning of said plurality of positioning feet upon said plurality of load-bearing feet, said radiused surfaces having multiple cross partitions formed therein.
