Refining tuyere system, for introducing combustion blast and/or oxygen into shaft smelting furnace, has refining tuyere tube concentrically connected with tuyere and firmly connected to stabilizing elements

摘要

A refining tuyere system comprises a refining tuyere tube (1), concentrically connected with the tuyere (3) on the mixing nozzle side and firmly connected to stabilizing elements (2), which: (a) are evenly distributed around the periphery of the tube; (b) are firmly connected to the mixing nozzle (5) in the region of the inlet cone (4); and (c) extend to the end of the tube, i.e. up to the receiver for location on the tuyere block of a shaft smelting furnace.
