Definitions

  • nozzle stones are known in which a nozzle tube penetrates the furnace jacket and the lining and is directly connected to it.
  • the gas supply is fixed centrally on the cover of the nozzle tube, the nozzle tube has an inward flange at the lower end, on which the nozzle plate rests.
  • a holding tube is attached to the lid, which presses on the top of the nozzle plate. Since the nozzle pipe is directly connected to the lining, it is difficult to replace it, the lining can be damaged by stresses, and the entire length of the nozzle pipe must be made of high-quality material. There is a risk of the nozzle plate seizing up on the nozzle tube and thus of a difficult replacement of the nozzle plate. In addition, the gas supply must be removed for repairs.
  • the figure is a cross section through a nozzle block.
