l煤粉在高炉内的去向煤粉由风口吹入高炉后，部分在风日前燃烧，部分以未燃煤形态进入高炉各部，参加各种反应或逸出炉外，其行为示于图1．除随炉顶煤气逸出炉外以及混于炉渣排出外，其余皆可认为是有效利用．强化高炉喷煤除配置良好的原料和施以正确的操作外，必须对煤粉吹入 l The location of pulverized coal in the blast furnace Pulverized coal blown into the blast furnace by the tuyere, some burned before the wind, some unburnt coal into the various parts of the blast furnace to participate in a variety of reactions or escape furnace, the behavior shown in Figure 1. Except as the top gas escapes from the furnace and is mixed with the slag, the rest can be considered as effective utilization. Strengthen blast furnace coal injection in addition to the configuration of good raw materials and apply the correct operation, you must blow coal
