摘　　要：对机组深调情况做了介绍,列出了锅炉结垢量、氧化皮趋势,对机组深调时发生的水汽、品质异常进行了分析,对深调影响凝结水氢电导率的机理进行了论述,得出了深调使凝结水浓缩导致氢电导率上升的结论,为火电机组在深调工况下出现水汽指标异常情况提供参考。It introduces the situation of deep adjustment of units,and lists the scale amount of boiler,the scale and the trend of scale cinder.It analyzes the abnormal water vapor quality during deep adjustment of units,and discusses the mechanism that deep adjustment affects the hydrogen conductivity of condensed water.It draws the conclusion that deep adjustment causes the concentration of condensed water to lead to the increase of hydrogen conductivity.It provides a reference for the steam index of thermal power unit being abnormal under the condition of deep regulation.

关 键 词：深调 氢电导率 浓缩倍率 杂质 结垢量
