摘要
介绍了煤泥浮沉试验过程中可能存在的问题,主要包括原煤不易润湿、低密度级煤的灰分高于高密度级的灰分等异常现象,并分析其原因及提出相应的解决方法。
The main problems existing in the coal float-and-sink analysis are introduced in this paper,such as the difficulty of being moisten for raw coal and the abnormal phenomena that ash yield in lower density coal is higher than that in higher density coal.And the reasons are analyzed and the corresponding solutions are proposed.
