不同煤种的缓慢灰化法和快速灰化法的比较

Comparison of slow method and fast method in ash determination with difference rank coal

通过慢灰法和快灰法对比不同煤种的灰分测定结果,得出:对于宁夏煤和准格尔3号煤,慢灰法和快灰法可以相互代替;而由于准格尔2号和准格尔5号煤之间存在较大系统误差,则该2种方法对于准格尔2号和准格尔5号煤不能相互代替。

The show and test method in ash yield determination with difference rank coal are compared,and it showed that slow ashing method and fast ashing method may both be suitable Ningxia coal and Zungeer 3# coal,and the two methods are not alternate for Zungeer 2# coal and Zungeer 5# coal because of bigger system error between Zungeer 2# coal and Zungeer 5# coal.
