What is the effect of adding deteriorated trisodium phosphate to boiler water?
Thread Content
As the title suggests, recently the concentration of phosphates in the boiler water of the plant dropped significantly (without any changes to the water supply volume or the amount of chemicals added). It was found that the chemicals had become damp, and it is suspected that this was caused by the dampness affecting trisodium phosphate, resulting in its loss of effectiveness. After adding new chemicals, the phosphate concentration returned to normal. I would like to ask the following: First, what chemical reactions occur when trisodium phosphate becomes damp and transforms into sodium dihydrogen phosphate and sodium bicarbonate, once these are added to the boiler water? II. What is the reaction of normal trisodium phosphate in boiler water?
I don’t think the concentration you add has much of an impact
