Abstract Scope |
The use of coke will be greatly reduced by much pulverized coal injection. The pulverized coal injection rate of blast furnace can be greatly increased by local oxygen-enrichment method. However, the cooling effect of room-temperature oxygen delays the devolatilization process and the entire coal combustion process will be delayed. To increase the pyrolysis rate will weaken the cooling effect. The pyrolysis rate increases and activating energy decreases with Fe2O3 addition. In this study, the effect of Fe2O3 on coal combustion in the blast furnace was simulated. The effect of Fe2O3 without oxygen-enrichment on coal burnout is unobvious. For local oxygen-enrichment, the coal burnout greatly increases and has a maximum increase of 22.03%. |
