Dear sea friends, is it necessary to add scale inhibitor to the heating boiler?
Thread Content
Hello, fellow sailors. Does anyone know that the maximum temperature of a atmospheric-pressure hot water boiler is 95°C? Is it necessary to add scale inhibitors to such boilers, and if so, what kind of equipment is required? What type of medication should be added? The water used in our boilers is water produced by a sodium ion exchanger. Our atmospheric pressure hot water boilers are used to provide heating for the factory area and office areas. The system is quite large; could adding scale inhibitors cause a sudden buildup of scale, thereby blocking the heating pipes? What should be considered when adding scale inhibitors?
I’ll take on this task first; I hope someone with relevant technical expertise can explain it! :):):):):):):):):):):):):)
Boiler heating water requires chemical treatment for maintenance； During operation, the furnace inspection requirements specify that the pH value of the boiler circulation water must be above 12; in other words, the boiler circulation water needs to be alkaline! Also, the circulating water in ordinary boilers is usually softened water, which has a low tendency to form scale but a tendency to corrode. Therefore, chemical treatment for maintenance is very important, and chemicals must be added as required by the boiler inspection during operation.
Hello, Haiyou. Do you know what kind of medication is generally suitable to add?
I don’t think it’s necessary to add any chemicals; ensuring proper hydration with soft water and a suitable hardness level is sufficient
Add trisodium phosphate to keep the pH between 9 and 11; if it’s too high, alkali foam will form in the water, making it difficult to control the liquid level. The temperature of the incoming water also needs to be controlled to prevent corrosion at the leakage points
