摘要
研究了煤粉的输送性能，结果表明：安息角不能准确地评判煤粉的输送性能，而应以单位时间的喷煤量作为判据；煤种、成品煤的性质等均与煤粉输送性能有关，粒度较大和粒度均匀的煤具有较好的输送性能；采用混合煤喷吹时，宜选用可磨性指数相近的媒．
This paper studies the transportation of pulverized coal. The results show that it can't be evaluated exactly by rest angle, but by the injection rate of unit time. Variety and nature of the finished coal are relative to it. Pulverized coal with homogeneity and bigger granularity has better transportation characteristic. It is suitable to choose the pulverized coal with close grindability index when adopting mixing injection.
