| Abstract Scope |
The blast furnace injection coal evaluation method is developed in this work. This method can be used to reflect the effects of coal injection changing to the utilization of coal powder and the blast furnace performance. The blast furnace smooth operation index and carbon content index are put forward. The blast furnace smooth operation index represents the effect of coal injection changing to blast furnace performance. The carbon content index represents the effect of coal injection changing to coal utilization. The method considers blast furnace operation parameters(blast volume, pressure difference),gas dust weight of per ton iron and gas dust quality etc. The blast furnace performance and utilization ratio of pulverized coal are evaluated effectively. The comparisons show the industrial trial well agree with the laboratory investigation, so the evaluation method is well validated. |
