Problems and Discussion on the Application of Catalytic Hydrazine for the Steam Generator Wet Layup
The activation energy of hydroquinone-catalyzed hydrazine deoxidization reaction is lower,the amount of hydrazine used is less,the dissolved oxygen in water can be removed quickly during the wet layup of steam generator,and the corrosion of steam generator alloy material can be reduced,it can also reduce the emission of hydrazine to the environment.Hydroquinone reacts with oxygen to produce p-benzoquinone,which has the sublimation characteristic.Entering the secondary loop water vapor system will cause jamming of the pontoon level controller.Therefore,it is necessary to reduce the concentration of catalytic hydrazine or replace the wet layup water before starting the reactor.In general,catalytic hydrazine for steam generator wet layup effect is good,and it is recommend for peers to use.
