This patent describes a method of operating a top blown Basic Oxygen Furnace in which oxygen is ejected vertically downwardly towards a charge in the Furnace. The improvement described here comprises: providing combination oxy-fuel burner and oxygen lance devices, each device comprising an elongate arcuate body having an inlet end and an outlet end; a support arm, the body being supported on the support arm adjacent the inlet end; a support base, the arm being pivotally mounted on the support based; means connected between the support arm and the support base to pivotally move the arm with the body relative to the support base, along an arcuate path between a lowered and a raised position; the elongate body having defined therein an inner generally central passage for flow of oxygen and an outer fuel passage surrounding the oxygen passage, the oxygen and fuel passages extending from the inlet end to the outlet end; the central passage having an inner wall and the outer passage having an inner wall; and a water in-flow passage and a water out-flow passage extending from the inlet end to the outlet end in spaced apart concentric side-by-side relationship and surrounding the fuel passage.
