As the oil crisis, environmental protection and coking coal resources increasingly scarce, blast furnace has not only the blast furnace is coal adjusted a and also an important way to make up for the lack of coke or major measures. And blast furnace ironmaking is to reduce production cost coal the effective way. This design with Baotou area of material condition and at home and abroad and advanced injection process of blast furnace study. The adoption and cans of direct injection from of pulverized coal injection way of 2200 m3design of blast furnace coal system. System of blast furnace design including coal storage system design,blast furnace coal pulverizing system design, blast furnace pulverized coal injection system design, blast furnace safety design of coal. And the low price of coal powder partly replace expensive and more lack of metallurgical coke, make the blast furnace ironmaking coke rate reduce, pig iron cost down. Increase benefits.
