SYSTEM FOR COAL BLOWING IN IRON OXIDE REDUCING KILNS Abstract A method and means for improved control of the process for directly reducing materials containing iron oxides in a rotary kiln using a solid carbonaceous reducing agent, such as coal, introduced from the charge feed and discharge ends of the kiln, as the source of both fuel and reductant, and oxygen-containing gas introduced along the kiln length is disclosed wherein the portion of the reducing agent fed at the discharge end is blown as a stream in a prescribed manner into the discharge end of the kiln. In particular, the important features of the stream are described including its longitudinal distribution and axial spread over the charge bed, as well as its contact region with the kiln walls and the quadrants of the kiln barrel into which it is di- rected, whereby the bed and gas phase temperatures may be controlled and heat transfer to the bed enhanced.
