煤中碳氢元素分析方法的研究

Study on ultimate analysis method of carbon and hydrogen in coal

利用全自动碳氢分析仪采用库仑分析方法对煤中碳氢元素分析进行研究。论述了其工作原理、试验条件、试验方法， 并对试验结果的精密度和准确度进行分析， 从而得出可用该方法进行煤中碳氢元素分析的结论。

By using full automatic carbon hydrogen analysis apparatus and coulomb analysis method, the ultimate analysis method of carbon hydrogen in coal was studied. Based on the principal, test condition and experimental method were introduced. The precision and accuracy of test result were discussed. It is confirmed that this analysis method is suitable for ultimate analysis of carbon and hydrogen.
