Abstract

The device comprises an oblique portion connected by a gooseneck, a nozzle, atuyere and a ball-and-socket joint to the wall of the furnace, in which the oblique portion comprises a tapered tube flange-mounted by its upper part onto an upper connection piece forming part of a bustle pipe and the lower part of which dips axially into a lower connection piece integral with the gooseneck, a bellows expansion joint and tension rods ensuring the mechanical connection between the tapered tube and the lower connection piece. The lower connection piece and the tapered tube can move mutually in the axial direction and have means for limiting their radial mobility.
