Abstract

The apparatus consists of a number of tubular components lined with a refractory inner lining (30) and connected, on one side, via an elbow (16), a nozzle (18) and a tuyere (20) to the wall of the furnace and, on the other side, to a circular main conduit arranged around the furnace and fed with preheated air. Cooling coils (36) are embedded within the refractory lining (30) and are fed with cooling air travelling through the coils (36) in the same direction as the preheated air and emerging into the internal channel (34) conveying the preheated air. <IMAGE>
