Fig. 5 Reaction of sample C along the path in BF: a changes in reduction fraction and carbon
conversion, and b changes in CO and CO 2 gas generating rates. (Color figure online)
Conclusions
In this study, using the CCB containing carbon: 20.30 wt%, Fe3O4: 29.70 wt%, FeO:
39.70 wt%, metallic iron: 1.57 wt%, and gangue: 8.73 wt% as the base sample. CCB
reaction behavior in BF was numerically investigated; and the influences of coal
reactivity on its reaction behavior were examined as well. Some conclusions could
be drawn and are the following.
(1) The development of the CCB reaction in BF included six stages. They were
reaction with BF gas, reduction with BF gas and partial self-reduction, CO 2 -rich
self-reduction, CO-rich self-reduction, partial self-reduction, gasification by BF
