【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。更多还原

【Abstract】 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.更多还原
