电厂水汽系统有机物含量对氢电导率影响试验研究

摘要

I n order to find out the co ntribution values of the organic matter content in the water vapor system of a power plant to hydrogen conductivity,water sample ion chromatographic analysis has been implemented,while the organic matter content in water vapor system detected at the same time. According to the data from ion chromatogra-aphy,the contribution of inorganic ions change in water vapor to hydrogen conductivity can theoretically be worked out,so as to indirectly work out the contribution of organic matter decomposition to hydrogen conductivity. The analysis indicates that the above results worked out conforms with the actual values. The organic matter in water vapor has comparatively important influence on hydrogen conductivity.%为探索电厂水汽系统中有机物含量对氢电导率的贡献值，在测定机组水汽有机物含量的同时，进行了水样离子色谱分析。根据离子色谱数据可以理论计算出水汽中无机离子变化对氢电导率的贡献，从而间接计算出有机物分解对氢电导率的贡献。分析表明：上述方法计算出的结果与实际值相符，水汽中的有机物对氢电导率存在较大影响。
