There are problems with trisodium phosphate used in boilers; urgent help needed! ! ! Kneel in gratitude
Thread Content
The situation is as follows: a new supplier has been chosen for the trisodium phosphate, and the product quality should be fine. After adding trisodium phosphate, it was found that the phosphate level would drop back to around 0.1 within half an hour at most. What is this problem? How to solve it? (The continuous shooting data usage isn’t very high.)
The inflow water hasn’t changed. If it’s a product issue, no matter how much trisodium phosphate deteriorates, phosphate ions should still be present, right? How can their concentration drop to just a few tenths in half an hour?
1. A purity analysis was conducted on the purchased trisodium phosphate; it is estimated to contain a certain amount of disodium hydrogen phosphate； 2. Strictly test the quality of boiler feed water, checking its hardness and silicate levels. 3. Analyze the phosphate content in the water discharged from the side drains and regular drains, as well as measure the volume of water discharged, in order to determine the balance of phosphate levels. By examining the above data, it should be possible to identify where the main problems lie.
