Exhaust gas cooling nozzles


Common issues with Gas Cooling process

  • Clinker issue for cooling tower and nozzles
  • Risk of corrosion
  • Nozzles dripping (excess water)
  • Problems caused by dust adhesion to interior walls or around outlet of gas cooling tower
  • In an installation where the  gas and sprayed water is coming from the top of the tower:
  • Unvaporized-water drainage needed from the lower part of the tower due to excess water

Solution: Innovative Gas Cooling Nozzles

We understand the significance of droplet size and full evaporation in gas cooling towers to ensure maximum cooling effect without extra drainage.

Therefore, we have a wide range of nozzles with different droplet sizes, spray capacities and spray angle to suit every request.

Customers realize lower running costs and minimal maintenance downtime with our clog-resistant nozzles and wide range of material options.

Example of Systems / Products used for gas cooling nozzles

  • ASPB series – Air-assisted Spillback Nozzles [NEW]

GSIMII series  Fine Fog Pneumatic Spray Nozzles


SPB series  Spillback Nozzles



  • Effective cooling with full evaporation
  • Minimal maintenance downtime
  • Lower running costs

Advantages of the solution

  • Clog-resistant nozzles
  • Wide range of material options like for anti-corrosion Titanium material, Hastelloy® or other
  • Wide range of spray capacity with minimal variation in droplet sizes and excellent atomization
  • Energy-saving nozzles with a low consumption of compressed air
  • For an installation of the nozzle horizontally from the side, the high-velocity fog reaches the center of the gas cooling tower without being disturbed by the exhaust gas flow
  • Other efficient installation is possible with different angle / positioning of the nozzle based on our recommendation and your plant’s layout


Other applications for these nozzles

  • Cooling: Gas, moldings, refractories, incinerators (flue gas desulfurization), cement factories, glass factories, blast furnaces, iron works, blast furnaces (dry dust catcher)
  • Moisture control: Flue gas, concrete, paper, cardboard, blast furnaces (water spraying to hot blast stove)
  • Combustion: Oil, waste fluid
  • Chemical reaction: denitration
  • Iron making process: Cooling flue gas before gas turbine, Cooling refractories at maintenance, Dust suppression at casting of pig iron
  • Steel making process: Cooling converter shell at maintenance, Flue gas cooling on electric furnace, Dust suppression at casting of steel
  • Rolling mill and surface finish process: Cooling flue gas from heating furnace, Dust suppression on rolling mill outlet
