摘　　要：对炉水中游离氢氧化钠浓度与电导率和pH值的关系进行探讨。结果显示,若遵照炉水氢氧化钠处理导则(DL/T—805.3—2004),机组在正常运行状态下,监督炉水的电导率就能控制NaOH的加入量,该方法方便快捷,可确保炉水中游离氢氧化钠不超标。An approach to the relationship between free sodium hydroxide in boiler water and its conductivity （or its pH value） has been made. Result shows that the dosage of NaOH can be controlled by supervision of the conductivity of the boiler water if according to the guidance of boiler water treatment by using sodium hydroxide （DL/T 805.3--2004）. This method is covenient and quick, can ensure the free sodium hydroxide in boiler water doesn＇t exceed the set standard.
