高灰分煤发热量测定的探讨

Discussion on determination of calorific value of high ash coal

对高灰分煤发热量测定的方法进行了探讨,并通过垫石棉的操作方法提高了高灰分煤炭发热量测定的精密度和准确度,使其能够达到国家标准GB/T 213—2008《煤的发热量测定方法》中重复性和再现性的要求。

This paper discusses the methods of determination of calorific value of high ash coal,and it is proved that the precision and accuracy of the determination by padding asbestos can reach the demands of the National Standard GB/T 213—2008.
