摘要
针对我国西南地区的煤质情况,分析了应用有源灰分仪检测的问题,阐述了天然射线灰分仪的原理,基于煤样的天然放射性测试结果,分析了该灰分仪在攀煤集团和代池坝选煤厂的应用情况。现场应用表明:天然射线灰分仪的使用效果良好,完全满足用户的要求,在西南地区具有较好的应用推广价值。
The coal produced in southwest China fluctuates widely in ash content. Following an analysis of the problems encountered in determination of the ash of the coal using active ash monitor, the paper goes to introduce the working principle of the natural gamma-ray ash monitor as well as the result of test made with coal sample and field application at the washer/ of Panzhihua Coal Group and Daichiba Coal Washer/. Practice shows the ash monitor can work with a performance well up to the requirement of the plants, and its widespread application in southwest China is well warranted.
