A burner including a first burner element having a first annular oxidant nozzle surrounding a first inner fuel nozzle; a second burner element having a second annular oxidant nozzle surrounding a second inner fuel nozzle, the second burner element being positioned adjacent to and spaced apart from the first burner element; a staging nozzle configured to flow secondary oxidant and being positioned adjacent to and spaced apart from the second burner element and separated from the first burner element by the second burner element; wherein the first inner nozzle and the second inner nozzle each have a major axis defined by a length L and a minor axis defined by a height h; wherein 5<=L/h<=15; wherein the staging nozzle has a major axis; and wherein the major axes of the first and second inner nozzles and the staging nozzle are substantially parallel with each other.

Burner and method for transient heating

A tuyere comprising an inner tube including a lower section having a first diameter, an upper section having a second diameter smaller than the first diameter, and a converging transition section having a converging angle &#x398; from 30&#xb0; to 60&#xb0; connecting the lower section to the upper section, the inner tube terminating in an inner nozzle at a downstream end of the upper section; and an outer tube surrounding the inner tube so as to create an annulus there between, the outer tube including a lower section having a third diameter larger than the first diameter, an upper section having a fourth diameter smaller than the third diameter but larger than the second diameter, and a converging transition section having connecting the lower section to the upper section, the outer tube terminating in an outer nozzle at a downstream end of the upper section.

Tuyere for a basic oxygen furnace

A system for melting a pelleted charge material including a furnace having a feed end configured to receive a solid pelleted charge material and a discharge end opposite the feed end configured to discharge a molten charge material and a slag, a conveyor configured to feed the pelleted charge material into the feed end of the furnace, at least one oxy-fuel burner positioned to direct heat into a melting zone near the feed end to heat and at least partially melt the pelleted charge material to form the molten charge material and slag, wherein the oxy-fuel burner uses an oxidant having at least 70% molecular oxygen, and at least one flue for exhausting burner combustion products from the furnace.
