ABSTRACT:
A diffuser (24) for an annealing furnace has a plurality of radially extending generally and vertically oriented vanes (40) for radially directing furnace gases. The vanes have top edges (42) defining a generally planar support and the top edges of the vanes have a notch (38) therein for receiving a conduit (34) preferably ring shaped that extend substantially around a center portion of the diffuser plate. The conduit (34) is connected to an inlet (32) for receiving enriching gases and exit ports (50) circumferentially space about said conduit (34) passing the enriching gases into the diffuser (24) to be mixed with ambient furnace gases.
