摘要
火电厂燃煤中氯含量是火电厂煤质评价、安全生产和环境保护的重要指标之一。引进国际标准方法检测煤中氯含量存在缺陷,本文对存在的主要问题进行了实验分析,结果表明:添加掩蔽剂和提高背景浓度相结合的处理手段使氧弹燃烧-离子选择性电极法更好适用于我国煤中氯含量的检测。
Chlorine content is one of the important indexes of coal quality evaluation, production safety and environ-ment protection in Coal-fired power plants. There exist defects during introduction of international standard method to detect the chlorine content in coal. In this paper, the main problems were analyzed,and the results shown that the problems can be solved by adding masking agent and improving background concentration processing means, which make bomb combus-tion-ion selective electrode method more suitable for detection of chlorine content in coal in our country.
