2种改善型煤种的配煤炼焦试验研究

Study on two kinds of modified coal blending tests

对柳林高硫焦煤和俄罗斯肥煤2种改善型煤种煤质进行分析,并分别对比同类常用炼焦煤,结果表明,柳林高硫焦煤和俄罗斯肥煤均为单一煤种,属于优质炼焦煤,具有较高的G值、Y值,可以作为配煤炼焦的基础煤种。20 kg小焦炉炼焦试验结果表明,2种改善型煤种单种煤所得焦炭质量较好,与其他煤种均有较好的配伍性。工业单独配用后焦炭质量的对比表明,2种改善型煤种可改善焦炭质量,降低企业配煤成本。

Analysis is made for two kinds of modified coals of Liulin high sulfur coking coal and Russian fat coal. Commonly-used coking coals of the same kind are also respectively analyzed. The result shows that the Liulin high sulfur coking coal and Russian fat coal belong to individual kind of coal of premium quality coking coal,with high G value and Y value,which are basic coal kinds for coal blending. The 20 kg pilot oven test shows that the two kinds of modified coals can produce coke of better quality and have high compatibility with other coal kinds. The commercial production shows that the two kinds of coals can improve coke quality and reduce the coal blending cost.
