高炉喷吹常村贫煤时煤粉的利用率

Utilization ratio of pulverized Changcun coal injection in a blast furnace lean coal in large amount of pulverized coal injection in a blast furnace

摘要: 根据岩相显微分析和化学分析的结果,计算了宝钢1^#高炉在进行常村贫煤工业实验时炉尘中未消耗煤粉中的含碳量,确定了常村煤的加入量在20%～40%的条件下炉尘中的含碳量和未消耗煤粉含碳量.给出了宝钢高炉在不同喷煤条件下煤粉在高炉内的利用率.

Abstract: The carbon amount of unused pulverized coal in dust and sludge during the industrial experiment of Changcun coal in Baosteel's 1^# blast furnace (BF) was investigated by microscopic and chemical analysis. The carbon amounts of s udge and dust and of unused coal were determined in the condition that the mass fraction of Changcun coal was about 20%-40%. culated in different conditions of pulverized coal injection in The utilization ratio of pulverized coal was cal Baosteel's BF.
