权利要求

1. A furnace comprising: a. a circular base; b. cylindrical side walls projecting upwardly from said base; c. a top portion covering said side walls; d. a peripheral tangential material inlet to said furnace at the bottom portion thereof for admitting material to be burned, and; e. outlet means in said base for discharging burned material, said outlet means comprising a hollow cylinder projecting concentrically into said furnace above said base.

2. The furnace of claim 1 wherein said top portion comprises a frustum of a cone.

3. The furnace of claim 1 wherein said circular base has a spiral ramp at the top thereof within said furnace surrounding said outlet means.

4. Combustion apparatus comprising: a. a circular base; b. cylindrical side walls projecting upwardly from said base; c. a top portion covering said side walls; d. a peripheral tangential material inlet to said furnace at the bottom portion thereof for admitting material to be burned, e. outlet means in said base for discharging burned material, said outlet means comprising a hollow cylinder projecting concentrically into said furnace above said base. f. Means for admitting combustible gas to said furnace; g. means for admitting solid material to be burned in said furnace in a stream of combustion supporting gases; h. means for conducting combustion products from said furnace; i. means for separating solid and gaseous combustion products; j. means for recirculating solid combustion products, and; k. means for discharging solid combustion products.

5. The combustion apparatus of claim 4 further characterized in that said circular base has a spiral ramp at the top thereof within said furnace surrounding said outlet means such that said tangential material inlet cooperates therewith.

6. A furnace comprising: a. a circular base; b. cylindrical side walls projecting upwardly from said base; c. a top portion covering said side walls; d. a peripheral tangential material inlet to said furnace at the bottom portion thereof for admitting material to be burned, e. outlet means in said base for discharging combustion products; f. and a spiral ramp within said furnace surrounding said outlet means such that said material inlet is near the bottom of said spiral ramp.
