摘要
采用德国Elementar公司生产的VarioELⅢ元素分析仪对几种电厂用煤的碳、氢、氮、硫各元素含量进行了测定 ,发现VarioELⅢ元素分析仪在硫元素含量的测定上存在着一定的误差 ,通过对元素分析仪测硫方法的原理及煤种自身特性进行分析 ,系统探讨影响硫元素含量测定的因素 ,并得出结论 :选择合适的标样测定煤样中的硫元素含量 。
The contents of C,H,N,S of different pulverized coals are measured with Vario EL Ⅲ elemental analyzers manufactured by Elemental Analysis in Germany. The errors between the metrical value of sulphur content and the standard value are found. Through the theoretical analyzing of the principle for sulphur measurement and the coal characteristics, the influencing factors on sulphur measurement are systematically discussed. The more accurate measured sulphur by choosing appropriate coal samples can be obtained.
