Abstract

Improvements introduced in a non-water-cooled blast furnace nozzle, characterized by the fact that it consists of at least one metal part provided with three ducts that lead directly into the blast furnace, of which one of them, the central one, receives the hot wind introduced by the nozzle, whose intermediate annular duct receives an oxidizing gas, preferably not pre-heated, loaded or not with pulverulent materials and selected from the group consisting of: oxygen enriched air, oxygen and water vapor mixture, oxygen and gas mixture carbonic, pure oxygen laden with water spray, pure oxygen, and whose outer annular duct receives a fluid or an emulsion containing hydrocarbons.
