  • Apparatus for production of direct reduced iron with reduced fuel consumption and emission of carbon monoxide
    Patent number: 6117387
    Abstract: A system for producing direct reduced iron wherein iron oxide material and carbonaceous material is passed successively through an oxidizing zone and a reducing zone of a furnace, each zone fired by oxy-fuel combustion, enabling a reduction in the amount of fuel needed to process the material while generating sufficient carbon monoxide to effect the reduction and ensuring that little or no carbon monoxide is emitted from the furnace.
    Type: Grant
    Filed: June 8, 1999
    Date of Patent: September 12, 2000
    Assignee: Praxair Technology, Inc.
    Inventors: Balu Sarma, Maynard Guotsuen Ding

  • Dual oxidant combustion system
    Patent number: 5904475
    Abstract: A dual oxidant burner having an inner conduit with a passage communicating with a source of fuel, an outer conduit over the inner conduit and an intermediate conduit between the inner and outer conduits. The three conduits form an inner passage between the inner and intermediate conduits communicating with a source of oxygen, and an outer passage between the intermediate and outer conduits communicating with a source of air. The fuel and the two oxidants are mixed in a furnace or other combustion zone beyond the outlet of the nozzle and the two passages and their flow amounts are individually adjusted to establish the burner flame.
