摘　　要：研究表明煤粉燃烧率不仅与煤种、煤粉粒径有关，而且还与煤质、显微组成和结构有关。采用混合喷吹和对一定煤种适当扩大煤粉粒径，尤其是烟煤的粒径，可能是进一步提高喷煤量和置换比的有效措施。Investigation and laboratory work show that the combustion rate of pulverized coal is not only determined by its rank and particle size but also by petrographic property. Possibly for a certain rank of coal, applying coal blending and making proper enlargement on particle size are of effective means for increasing BF coal rate and replacement ratio of coal.
