摘要(Abstract)：

提出了一种基于双水膜脱气法和电再生离子交换技术相结合的水汽脱气氢电导率多参数协同监测系统及方法，可快速测量电导率、氢电导率、脱气氢电导率和pH值等多项关键水质指标，对水质做出综合评判，指导停机启动及正常运行水工况调整，对保障水汽品质及热力设备腐蚀、积盐、结垢的防控具有重要意义。其中，脱气氢电导率测量采用双水膜脱气技术，可高效脱除水中CO_2，在此基础上提出标准溶液校准脱气氢电导率测量值的方法，可有效评判测量值的准确性。该方法用于典型的燃气联合循环机组、供热机组的现场监督，结果表明其测量准确性高，可快速综合评估水汽品质，能辅助解决现场出现的各类技术问题，具有很强的推广应用价值。
