Abstract

A tuyere for an oxygen blast furnace has a body and a first conduit extending through the body. The first conduit is adapted to receive a medium at one end of the conduit and discharge the medium at a second end of the conduit through at least one discharge nozzle. A second conduit can be arranged concentrically around the first conduit and is adapted to receive a medium and discharge the medium through at least one discharge nozzle. In another aspect, a portable oxygen blast furnace system includes oxygen blast furnace secured to a railcar. The portable furnace system can be transported by rail for processing material at remote locations.
