Abstract
The high-temperature burner assembly of the present invention includes an oxygen containing nozzle body which has a gas conduit insert disposed therein. The gas conduit insert includes a gas conduit insert tip which has a substantially flat exterior tip face with a frusto-conical shaped prominence disposed thereon and protruding from the tip face. The gas conduit insert tip includes a centrally disposed gas channel terminating at the proximal end of the frusto-conical shaped prominence to form a knife edge to provide reduced available surface for accumulation of carbon and for briefly delaying the combustion. An oxygen expelling orifice is concentrically disposed about the frusto-conical shaped prominence for directing oxygen therefrom to mix with the gaseous fuel for combustion within a refractory burner block.
