Iron and steel

GEA Bischoff provides the following technology for the iron and steel production sectors:

• Coking plants
  • Detarring of process gases by means of wet-type electrostatic precipitators
• Ore Beneficiation
  • Cleaning of process and secondary gases from sintering, pelletizing and reduction plants using electrostatic precipitators (MEEP technology, for example), scrubbers or fabric filters
• Pig Iron Production
  • Coarse dust separation by means of dust catchers
  • Fine dust cleaning by using annular gap scrubbers or dry-type electrostatic precipitators
  • Energy recovery with top-gas expansion turbine
  • Cast house dust collection by capturing via extraction systems and cleaning in fabric filters
• Oxygen Steel Plants
  • Dry type Lurgi-Thyssen (LT) Steel Gas process
  • Wet dedusting of converter off-gases with annular gap scrubbers
  • Capturing of secondary emissions via extraction systems and dedusting by fabric filters
• Electric Arc furnaces
  • Combustion and cooling of primary gas in boiler components, with gas/air coolers as required
  • Capturing of secondary emissions via extraction systems and dedusting by means of fabric filters
  • Cleaning of primary and secondary offgases or combined in a central separator
• Rolling mills
  • Gas cleaning in rolling mills
• Cogeneration
  • Mainly using wet electrostatic precipitators upstream turbines as contribution to energy/Co2 saving
