BLAST FURNACE TUYERE

摘要

A blast furnace tuyere has a nozzle with a double tubular jacket wall between which there flows a cooling fluid which is guided by a flow guide installed between the two jacket walls, so that the cooling fluid flows over the inner surfaces of the two jacket walls around the guide. The flow guide occupies substantially the whole of the space between the inner and outer jacket walls adjacent to the nozzle mouth, leaving only a narrow gap through which the cooling fluid can flow.
