Provided is a burner which includes a pipe having a free end region designed to be housed in a furnace quarl. The pipe includes one or more fuel feed ducts surrounded over part of their length by a sheath which defines an oxidizer feed channel and is fastened to a flange. A jacket is disposed around at least part of the length of the end region so as itself to be housed in the quarl and to define a feed channel for a second oxidizer between the jacket and the internal wall of the quarl. The jacket is fastened to a flange for securing to the quarl and the flange for the sheath is fastened to that for the jacket. The burner has particular applicability in industrial furnaces, especially for melting non-ferrous materials, for rehearing or for annealing.
