摘要
通过对单种煤粉进行工业分析、元素分析及可磨性、灰分成分、灰熔点、爆炸性、着火点、燃烧率测定,确定3#烟煤和III#无烟煤为邯钢高炉喷吹用烟煤的首选煤种。混煤能发挥无烟煤和烟煤各自的优点,随着烟煤配比的增加,燃烧率逐步增大。综合考虑,烟煤比例控制在45%～55%较为适宜。
By testing industrial analysis, elementary analysis, grindability, ash composition, ash fusion point, explosiveness, flare point, burning rate, 3# bituminous and III# anthracite would be the first choice. Burning rate of mixed coal increased gradually by the increased amount of bituminous coal. Above all, it was suitable that bituminous coal ratio controlled 45%~55%.
