Exhaust gas cooling nozzles

Process

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 this solution

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

GSIMII series  Fine Fog Pneumatic Spray Nozzles

SPB series  Spillback Nozzles

Solutions

Benefits

  • 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
