Title:
METHOD AND APPARATUS FOR AFTER-BURNING ATMOSPHERIC GASES IN A STEEL SMELTING ARC FURNACE
Document Type and Number:
WIPO Patent Application WO1997002366
Kind Code:
A3
Abstract:
Method and apparatus for introducing oxidizing gas, e.g. oxygen into the atmosphere of an electric arc furnace to effect post combustion (after-burning) of gases in the atmosphere and provide a radiant heat source (18, 36) inside the furnace. The apparatus (10, 70) has a generally cylindrical shaped with a first end (34) for introducing oxidizing gas tangentially (54, 56) inside the apparatus (radiant injector) (10, 70) and a second end or exit portion (32) having a flared opening (36) to discharge swirling oxidizing gas into the furnace. The apparatus (10) is refractory or has a refractory coating on the surfaces which are exposed to the furnace atmosphere and which when further heated become a radiant heat source in the furnace.
