摘要
研究了焦化温度、焦化时间、粒度和放置时间对无灰煤粘结指数测定的影响,无灰煤粘结指数测定的适宜条件为焦化温度850℃,焦化时间11min,样品粒度小于0.2mm,样品制备后放置时间不宜超过5天。
The influence of coking temperature,coking time,grain size and storage time to the determination of caking index of ash-free coal is studied,and the result shows that the most favorable conditions for determination of caking index of ash-free coal are as follows： coking temperature：850℃,coking time： 11 min,grain size： less than 0. 2mm,and storage time： no more than 5 days after preparation of sample.
