Outotec® Cooling Concept Upgrade for Pelletizing

Increase the energy efficiency of your induration furnace with our cooling concept upgrade. The upgrade recycles air in the cooling zone by dividing it into three sub-zones, replacing the single fan with two to three smaller fans, and cooling with recuperated hot air.

  • Reduces total gas volumes
  • Increases recuperation duct gas temperature
  • Increases UDD temperature for more efficient and gentle drying
  • Reduces the thermal shock from cooling
  • Results in better quality product pellets with fewer cracks
  • Enables fuel savings and slightly decreased electrical power consumption
