摘　　要：某供热机组供热季出现水质异常,炉水pH异常增大,最大值达10.65,省煤器进口氢电导率最大达0.47μS/cm,均超过了水汽异常三级处理标准,及时对凝结水各疏水系统进行分析,经过离子色谱检测,确定热网加热器疏水异常引起机组水质异常,经过检测热网加热器确定泄漏量最大为40L/h,并及时采取措施,保障了机组的安全稳定运行,避免类似的情况再次出现。Abnormality of water quality of a heating unit in the heating season,and the pH of boiler water increases abnormally,with the maximum value of 10.65,and the maximum hydrogen conductivity at the inlet of economizer is 0.47μS/cm,which all exceed the three-level treatment standard for water vapor anomalies.Analyze all drainage systems of condensate in time.Analyze all drainage systems of condensate in time.Through the method of Ion Chromatography(IC),it is determined that the abnormal water quality of the unit caused by abnormal drainage of the Heating network heater,and the the maximum leakage is 40 L/h,and And taking measures timely to ensure the safe and stable operation of the unit and avoid the recurrence of similar situations.
