Abstract: Solid fuels are gasified in a fixed bed with gasifying agents passed through the fixed bed from below. The gasification residues are withdrawn as solid ash or as liquid slag under the fixed bed. The reactor is charged with solid fuels through a lock chamber and with tar through a supply conduit. The tar is delivered to the fuel in numerous individual streams, which are distributed over the cross-section of the fixed bed.In the gasifying reactor, an inclined distributor surface is disposed over the fixed bed and has numerous passage openings for the tar and the solid fuels. The outlet end of the tar supply conduit is directed to the upper portion of the distributor surface. A tar tub having outlet openings is associated with the distributor surface and serves to receive the tar. The distributor surface is rotatable on a vertical axis.

Abstract: In a process for gasification of solid carbonaceous material such as coal, powdered coal is top-blown onto a molten iron bath stored in a furnace through a non-submerged lance toward a hot spot formed by means of a jet of oxygen and steam top-blown through a non-submerged lance, the coal being blown by means of a carrier gas, and flux is optionally added into the furnace by the lump or blown toward the hot spot, thereby resulting in the coal being gasified. The ratio L/L.sub.o of the depression depth L of the molten iron bath to the molten iron bath depth L.sub.o is maintained from 0.05 to 0.15, and the blowing velocity of the solid carbonaceous material is maintained from 50 to 300 m/sec so as to suppress the formation of an adhered mass on the upper part of the furnace, hood or lance.

Abstract: Briquettes made of mainly coal are described to which there has been added 10 to 30% by weight of ash (other than ash which is contained in the coal normally). The briquettes formed from such a mixture have strength which permits them to be subjected to gasification or carbonization in a fixed bed. Also described is a method for forming the briquettes.

Abstract: A coal gasifying burner characterized by a rotating grill which is composed of grill disks arranged on two pipes with a narrow gap between the grills and which rotates very slowly inwards when viewed from the top sloped side walls made of metal sheet having a sloper compatible with coal flow, a cylindrical jacket placed around the periphery of the nozzle which delivers combustion air to the burner, gasification of a quantity of coal located on the sloping side walls around a narrow area where coal combustion takes place, and combustion of the generated coal gas outside of the burner by secondary air which cools the system and gets heated itself by the coal cooking process.

Abstract: A process and apparatus are provided for converting particulate carbonaceous fuel, such as high-sulfur bituminous coal, into a combustible gas, the process comprising forming an ignited fluidized bed of said particulate carbonaceous fuel in a closed-bottom shaft furnace, the shaft furnace having a roof enclosure, directing a jet stream of oxygen downward into the bottom zone of said ignited fluidized bed of particulate fuel by means of an oxygen lance passing axially through said roof enclosure in sealing engagement therewith, the velocity of said oxygen stream into said bottom zone being sufficient to form a dynamic highly turbulent suspension of said particulate fuel and its particulate reaction products deflecting substantially radially outwardly and upwardly and then inwardly and downwardly in a toroidally circulating manner in the bottom zone of said fluidized bed, continuously removing effluent gases formed by the reaction of said oxygen with said fluidized bed, and maintaining said fluidized bed by continually feeding makeup fuel to said shaft furnace.When the jet-fluidized bed is operated continuously below ash-fusion temperatures, said bed will accumulate and maintain a high percentage of particulate ash which is continuously withdrawn from the furnace.When the jet-fluidized bed is operated above ash-fusion temperatures and fluxes and sulfur fixation agents are fed with the coal, a molten bath is formed on the bottom of the furnace, said bath serving to collect ash, sulfides, iron, and other coal impurities in molten products which flow out of the furnace through tap holes.
