Gas cleaning plants

Broad portfolio of gas cleaning solutions

The melting process generates up to 20 kilograms of dust per ton of steel. This goes into the exhaust air where it represents a big problem. You need to clean the exhaust air to ensure sustainable steel production and comply with clean air regulations. Whatever your furnace type - whether electric-arc (EAF), basic oxygen (BOF converter), argon oxygen decarburization (AOD converter), or submerged-arc (SAF) - we offer you the right technology. Our range includes:

  • Complete gas cleaning plants for all metallurgical equipment
  • Primary gas cooling / dedusting
  • Secondary dedusting
  • Gas recovery (BOF, SAF)
  • Dedioxization (by lignite coke)
  • Desulphurization
  • EFATM process

Energy recovery

Broad portfolio of energy recovery solutions

The most important energy input in the steel industry comes in the form of heat. That goes for processes all along the process chain - from steelmaking plants to processing lines. Yet generating combustible gases often wastes precious thermal energy.
That's why we developed several solutions to recover energy from:

  • Hot off-gas from EAF, BOF, AOD, and SAF using evaporation-cooled ducts or waste heat boilers
  • Combustible exhaust gases using industrial power plant technologies
  • Hot off-gas with reheating furnaces
  • Hot slabs with innovative heat exchangers
