探讨了蒸汽发生器（ＳＧ）湿保养期间，低温催化联氨除氧方法中催化剂对磷酸盐——联氨水质ｐＨ的影响，并对温度、催化剂用量、联氨用量对联氨除氧速率和除氧效率的影响进行了试验研究．试验结果表明：温度、催化剂用量、联氨用量对除氧速率和除氧效果有一定的影响．温度为３５℃，联氨用量为氧含量的６倍，对苯二酚略高于１０μｇ／Ｌ时，２０分钟可将水中氧含量降至１００μｇ／Ｌ以下，当对苯二酚为５０μｇ／Ｌ时，３分钟之后氧含量就可低于１００μｇ／Ｌ，２０分钟后可低于１０μｇ／Ｌ．
The effect of catalyst on the pH value of phosphate - hydrazine in hydrazine gas during the wet maintenance of steam generator (SG) was discussed. The effect of temperature, amount of catalyst and hydrazine on the rate of oxygen removal by hydrazine Oxygen efficiency of the experimental study. The experimental results show that: the temperature, the amount of catalyst, the amount of hydrazine on the oxygen rate and oxygen scavenging effect to some extent. When the temperature is 35 ℃, the amount of hydrazine is 6 times that of oxygen and the concentration of hydroquinone is slightly higher than 10μg / L, the oxygen content in water can be reduced to below 100μg / L in 20 minutes. When hydroquinone is 50μg / L The oxygen content may be less than 100 μg / L after 3 minutes and less than 10 μg / L after 20 minutes.
