摘要(Abstract):

针对内蒙古2个火电厂水汽氢电导率异常情况,通过离子色谱分析仪和总有机碳分析仪对汽水系统中的痕量阴离子及有机物进行检测,认为A电厂氢电导率异常是由于新投运了尖峰冷却系统,尖峰冷却系统内杂质进入汽水系统,导致汽水系统氢电导率升高;B电厂氢电导率超标是由于生水加热器泄漏,生水经由辅汽疏水管路进入凝汽器,导致凝结水氢电导率超标,同时提出了相应的整改措施。
The steam quality of hydrogen conductivity is abnormal in two thermal power plants of Inner Mongolia, ion chromatography and total organic carbon analyzer were used to detect the trace anions and organic matter in water vapor, that the anomaly hydrogen conductivity of one power plant is due to run peak cooling system, the impurity of peak cooling system within the water systems, resulting in the increased hydrogen conductivity. The anomaly hydrogen conductivity of the other power plant is due to water heater leakage, water drainage pipeline through the auxiliary steam entering the condenser,resulting in condensation of water hydrogen conductivity exceed the standard. For the issues mentioned above, the author put forward the relevant countermeasures.
