SSiC Spiral Nozzle


Silicon carbide spiral spray nozzle, AKA desulfurization nozzle or dust removal nozzle, is adopted for exhaust gas washing, gas cooling, washing and bleaching, fire prevention, smoke desulfurization and dust removal system, etc. With high strength, high hardness, corrosion resistance, wear resistance, high-temperature resistance and other excellent properties, it boasts a long service life under severe conditions, and is the key component of the thermal power plant, large-scale boiler, desulfurization and dedusting equipment.

It includes the hollow cone and the solid cone. Along with the continuous decrease of spirochetes, the slurry, after continuous tangent and collision of the helix, changes its direction and sprays into a concentric axial cone, and the liquid will not be jammed in the nozzle. And it still performs a high absorption rate under low pressure.

Oustek’s spiral nozzle adopts isostatic pressing, net size sintering and mechanical finishing technique, it produces a spiral nozzle with density up to 3.1kg/m³. Adopts silicon carbide for high-quality refractories with purity up to 98.5%, so the maximum working temperature reaches up to 1380 ℃ (2500 ℉), with continuous service hour reaches up to 9000 hours. The spray particle diameter is about 2200um, with small spray angle deviation and flow deviation within the allowable range.


  • Desulfurization and denitration of power plants and coal-fired enterprises
  • Purification, cooling and defoaming of gas
  • Evaporation, cooling and dust control
  • Environmental protection wet dust removal spray
  • Pre-treatment requires non-blocking spray.
  • Gas cooling
  • Waste gas washing
  • Fire protection and Application
  • Dustproof application in steel and petrochemical industry


  • With porosity lower than 0.1% and atomization more uniform, smoothing the internal flow channel.
  • High strength, high hardness, wear resistance, density up to 3.1kg/m3.
  • High thermal conductivity, low thermal expansion, high thermal shock resistance, high temperature creep resistance.
  • Chemical stability, corrosion resistance, especially hydrofluoric acid resistance.
  • High-temperature resistance, maximum operating temperature up to 1380 ℃ (2500 ℉).
  • Long service life and reduce overall investment cost
