摘要
通过选取不同炼焦煤的特征指标,对微波干燥前后这些特征指标的分析比较,探索微波干燥技术对炼焦煤煤质的影响.结果表明,微波干燥技术在去除炼焦煤水分的同时,对炼焦煤的工业分析和黏结指数无明显影响;对基氏流动度和奥亚膨胀度存在正影响,但不明显;对胶质体影响较大,特别是其过程行为.因此微波干燥技术对炼焦煤煤质无较大影响,如果存在影响,也是有利于改善炼焦煤煤质的.
This paper is aimed to discuss the influence of quality of coal with microwave dry technique, by selecting and analysing different characteristic indexes of coking coal. The re- sults show that the microwave dry technique has no obvious effect on proximate analysis and ca- king index while removing the humidity of coking coal, no obvious positive effect on the Gieseler fluidity and Audiberts Arnu dilatation and large effect on behavior of colloid. The microwave dr- ying technique has little effect on the quality of coking coal and is also advantageous to improve the quality of coking coal.
