煤水分的测定一直是沿用传统的烘干失重法。这种方法的优点是测量精度高,受外界因素影响小,但测量时间太长,至少需要两个小时以上才能测得水分值,不能及时指导生产。在鹤岗矿务局选煤厂的支持和协助下,研制成功了WB-1型微波煤水分快速测定仪,并通过了技术鉴定。该仪器采用取样测试,将样品装入取术器后,选进行密度控制(约10秒钟)的处理,然后插入仪器测试孔,便立即显示煤样的水分值。 Determination of coal moisture has always followed the traditional method of drying weight loss. This method has the advantage of high accuracy, small external factors, but the measurement time is too long, at least two hours or more to measure the water value, can not guide the production. With the support and assistance from Hegang Mining Bureau Coal Preparation Plant, the WB-1 microwave coal moisture analyzer has been successfully developed and passed the technical appraisal. The instrument uses a sampling test, after the sample is loaded into the surgical instrument, the density control (about 10 seconds) is selected and then inserted into the instrument test hole to immediately display the water content of the coal sample.
