摘要
对汾西矿业不同煤化程度焦煤、肥煤的煤质指标、基氏流动度、奥亚膨胀度和镜质体最大反射率进行分析。结果表明,不同变质程度的焦、肥煤具有明显不同的煤质特征,低变质程度肥煤具有高挥发分、高流动度和高膨胀的特点;高变质程度肥煤具有低挥发分、低流动度和低膨胀的特点。同时,通过焦、肥煤的焦炭强度分析,为各焦化和钢厂的配煤炼焦提供依据。
Varying degrees of Fenxi coal mining eoking coal, fat coal quality indicators, Gieseler fluidity, Audibert Arnu dilata- tion and maximum vitrinite reflectance are analyzed. The results indicate that different metamorphic grade coke, fat coal have significantly different characteristics of coal. Fat coal with a low metamorphic grade is highly volatile,and has high fluidity and high expansion characteristics. A high degree of fat coal metamorphism has low volatile, low liquidity and low expansion char- acteristics. Analyzing the coke, fat coke strength provides the basis for the coking and steel coking coal blending.
