  • Method for producing non-abrasive coke forms from brown-coal briquets
    Patent number: 4134794
    Abstract: The coke forms are produced in four stages, each constituted by a respective oven chamber, and in which the briquets are, respectively, preheated, dehydrated or dried, carbonized and cooled. Hot gas circuits are provided, in which the hot gas is composed substantially of burnt lean gas of the carbonization, and, for each stage, the hot gases are recirculated in a separate respective circuit. In the preheating, dehydrating and carbonization stages, the hot gases are heated and produced, or supplemented, in a respective separate combustion chamber with the recirculating hot gas in the carbonization stage being supplemented with cooled lean gas from this stage. The recirculating hot gases are dedusted separately in a dust settling chamber in which their flow velocity is reduced to approximately 0.2 to 2.0 m/sec, with the dust being collected.
    Type: Grant
    Filed: September 28, 1977
    Date of Patent: January 16, 1979
    Assignees: Firma Carl Still, Rheinische Braunkohlenwerke Aktiengesellschaft
