Definitions

  • the present disclosure generally relates to an improved burner useful in apparatus such as auxiliary burners used in metal melting, decarburization, refining and processing, for example, steel making in an electric arc furnace (EAF) or blast furnace.
  • EAF electric arc furnace
  • auxiliary burners are used to assist in the steel making process to add thermal energy by the combustion of fuel, the injection of oxidizing gas for melt refining, foamy slag production or post combustion of carbon monoxide, and the injection of particulates for slag and foamy slag production.
  • the oxidizing gas is introduced as a high velocity stream that may exceed sonic velocities.
  • a burner tip defining a parabolic main oxygen nozzle and V-shaped fuel supply ports; an oxygen supply tube removably attached to a burner tip for ease of cleaning or replacement and a burner tip with a tapered outer diameter for an improved mechanical seal.
  • One aspect of a preferred embodiment of the present disclosure comprises a burner, comprising an oxygen supply tube and a burner tip defining a concave face; wherein the burner tip defines a main oxygen nozzle having a parabolic shape.
  • the oxygen supply tube is removably attached to the burner tip.
  • an outer diameter of the burner tip is tapered.
  • the concave face defines a plurality of V-shaped fuel supply ports.
  • a burner comprising an oxygen supply tube removably attached to a burner tip; wherein the burner tip has a tapered outer diameter and defines a concave face; wherein the burner tip defines a main oxygen nozzle having a parabolic shape; and wherein the concave face defines a plurality of V-shaped fuel supply ports.
  • FIGS. 1-5 show a preferred burner 10, such as a "decarb burner” or other types of burners such as for an EAF (Electric Arc Furnace), blast furnace or other type of metallurgical furnace, of the present disclosure, comprises an oxygen supply tube 12 and a burner tip 14 defining a concave face 15.
  • Burner tip 14 and/or concave face 15 preferably define a groove 17 machined or otherwise, a main oxygen nozzle 13 having a parabolic shape and a plurality of V-shaped natural gas ports 16.
  • the outer diameter 19 of burner tip 14 preferably is tapered to provide an improved mechanical seal.
  • the burner 10 preferably comprises a ceramic pilot ignitor.
  • sizes of the burner tip 14 range from 3 inches to six inches in diameter.
  • the burner 10 may be of various lengths and water-cooled or not water-cooled.
  • the oxygen supply tube 12 is removably attached to the burner tip 14 of burner 10 to provide for ease of cleaning and/or replacement of the supply tube 12 or burner tip 14.
