潞安煤在钢铁厂单独喷吹的应用

Application of single injection of Lu'an coal in iron plant

对使用潞安煤单独喷吹的钢铁厂的煤粉煤质与喷吹特性进行分析,指出以潞安煤为代表的贫煤、贫瘦煤,其挥发分适中、爆炸性低、磨煤特性好,可进行高炉单独喷吹并具备其优势。

This paper analyzed quality of budgust and injection characteristics of Lu＇an coal which was used in iron-works alone for injection,and indicated that for Lu＇an coal which is the representative type of meagre coal and meager lean coal,it has suitable volatile matter,low explosiveness and good grinding property,which would be feasible and advantageous for injection alone in blast furnace.
