Abstract

An oxygen-fuel burner of the rocket burner type includes a graphite burner block (11) for direct exposure to the interior of a furnace, and a cylindrical combustion chamber (115) formed through the hot face of the burner block and extending into the burner block. An oxygen supply conduit (15) delivers oxygen to the combustion chamber along the center line of the combustion chamber and fuel supply ducts (109 and 110) deliver fuel to the combustion chamber at the concave surface of the combustion chamber, whereby fuel surrounds the stream of oxygen. Excess oxygen can be supplied by the nozzle (82) to provide more oxygen than consumed by the flame, whereby the excess oxygen is preheated as it passes through the flame and can be used in a lancing process in the refining of steel.
