  • Patent number: 4544374
    Abstract: Separation of the apparatus for drying and degassing organic waste from the shaft furnace containing a gasification chamber and a combustion chamber increases the through-put capability of the shaft furnace gasification. The gasification is promoted by the addition, in the same direction of flow as the partly carbonized waste material, of a gas such as air, steam, carbon dioxide or oxygen adjusted in accordance with the changes in composition of the material that is gasified. The drying and degassing chamber is a rotary drum feeding the dried and degassed material into the top of the shaft furnace. An intermediate chamber may be imposed between the rotary drum and the shaft furnace at the top of the shaft furnace so that a sieve can separate incombustible material such as metal parts for withdrawal through a gas-tight sluice.

  • Patent number: 4049385
    Abstract: An apparatus for carrying out chlorinating reactions when extracting metals uch as titanium, zirconium or the like during the extraction of uranium and thorium during the reprocessing of burned-off fuel and/or breeder elements for core reactors and during the purification of coal and graphite. The device comprises a shaft or blast furnace which is heated by a direct flow of current and while being coaxially surrounded by a mantle or shell communicates through a connection or adapter piece with a subsequent condenser of graphite. The device according to the present invention is characterized primarily in that the shell of the furnace and the adapter piece connecting the furnace with the condenser are made of graphite. The shell of the furnace, the condenser and the adapter piece connecting the shell with the condenser are arranged within a steel casing designed in a gas-tight manner.
