摘要
煤中全硫测定是煤质分析的一项重要指标。本文从煤样的粒度和均匀性,载气流量,电解液的使用,电解池和电极片的处理,库仑测硫仪的校正等方面对应用库仑法测定煤中全硫应注意的问题及原因进行分析,以确保测定结果的准确性。
The total S in coal is an important index in the coal analysis. In this paper, we analysis the serious problem and cause in the total S determination of coal with Coulomb method according to the grain size and uniformity of sample, flow amount of loading gas, application of electro lyzed solution, processing of electrolytic tank and electrode slice and correction of Coulomb S detector, etc in order to guarantee the accuracy of determination result.
