摘　　要：高炉喷吹煤粉有降低焦比、合理利用煤炭资源、减少环境污染、降低生产成本等作用。然而随着入炉煤粉量的增加,煤粉的燃烧率会有所下降,煤粉燃烧率是制衡高炉喷吹煤粉量的主要因素。文章探讨了高炉喷煤技术发展的特点,同时基于煤粉输送条件,对煤粉燃烧率的影响展开了研究。The blast furnace pulverized coal injection has the effect of reducing coke rate and rational utilization of coal resources, reduce environmental pollution, reduce the production cost.However ,with the increase of the amount of pulverized coal into the furnace, the combustion rate of pulverized coal will be decreased.This paper discussed the characteristics of the development of pulverized coal injection technology of blast furnace, and studied the influence of pulverized coal conveying conditions on the combustion rate of pulverized coal.
