Some facts about sinter plants in Europe (EU 15) in 2013
•
29 strands were operated in 2013
•
Average suction area was 288 m2 (smallest 90 m2, largest 589
m2 )
•
8 strands have a suction area of over 400 m2
•
Highest productivity was 59.5 t/m2 x 24 h as yearly average
•
Lowest fuel consumption was 1206 MJ/t sinter as yearly
average
•
Sinter plants enable to recycle in-plant residues

Conclusions
• Blast furnace converter route is dominant (60 %)
• The companies invest in the blast furnace route
• Nearly all blast furnaces are equipped with PCI
• Challenge for steel makers in EU to reduce CO2 emissions
• Development of new CO2 lean processes
• CO2 breakthrough is only possible when applying CCS
• Iron making in blast furnace plants has changed from
“old economy” to “factory of the future”! Clean, highly performing,
environmental friendly, socially sustainable
