Schack® Air Preheaters in the furnace carbon black process preheat process air for reactors. Process gas heat is regained and positively affects the operation costs by 

  • rise in carbon black production yield
  • reduction in fuel consumption
  • increase in feedstock flow
  • reduction in quench water consumption

Increased air preheating temperatures support these positive effects and also reduce CO2 emissions of the process.

For the carbon black process Schack®Air Preheaters (APHs) are designed on basis of the principle “flue gas through the tubes”. The combustion air in the air preheater shell is directed around the tubes by means of baffles.

Schack® Air Preheaters are of standardized design. They are selected according to the requested process parameters.
