Coke production capacity within AM FCWE is not self sufficient for
the total HM production. PCI was started up in 2004 at Bremen BF2
and Eisenhüttenstadt BF5, with a ramp up to 180 kg/thm in one year.
A working group defined the BF operating conditions leading to stable
and efficient operation at high PCI. At Florange BF3 PCI trials at
220 kg/thm were successful. At Dunkerque BF4 and Gent BFA and
B, the PCI rate exceeds regularly 210 kg/thm.
