煤样分层式干燥机性能试验研究

Experimental study on performance of coal sample layered dryer

设计了一种煤样分层式干燥机,为检验其是否可应用于商品煤样的制备过程,对其开展了性能试验研究。研究结论为:干燥机煤样损失率为0.14%;相比于国标方法,分层式干燥机干燥效率更高;以分层式干燥机作为设备方法,恒温干燥箱作为国标方法,对于灰分指标,设备方法可以替代国标方法。分层式干燥机可以用于商品煤样的制备过程。本研究分析了煤样的灰分指标,如有必要,建议进一步开展其他指标的试验研究。

Designed a coal sample layered dryer.In order to test whether it can be applied to the preparation process of commercial coal samples,carried out experimental study on its performance.The conclusion was:Coal sample loss rate was 0.14%;the drying efficiency of layered dryer was higher than the standard mothed;See layered dryer as equipment method,and see thermothermal drying box as standard method,for the four indicators of ash value,the equipment method could substitute the standard method.Layered dryer could be used in the preparation process of commercial coal samples.This study analyzed four indicators commonly used of commercial coal samples.If necessary,suggest carry out further experimental research on other indicators.
