煤样不同干燥方式对化验指标的影响

the difference drying ways of the coal sample on laboratory index

煤样的干燥方式不同，煤样分析水和粘结指数的试验结果不同，通过对多种精煤一系列试验表明。烘干箱和电热板对煤样都存在过干燥的问题；而对粘结指数，由于电热板试验时间较短，试验结果更有代表性。

The moisture in the general analysis test sample of coal and the caking index are different when the coal drying in deferent ways. It shows the coal sample is drier when the drying box and the electriothermalplate has been used through a series of experiment of the varied cleaned coal;The caking index is more representive because of the using of the electric heating board.
