Hi Everyone,
I have a high pressure water boiler leaked after very short upset in the boiler feed water pH: the pH was around 3 to 4! Has anybody come across such thing? What might be the causes? The steam condensate makeup is demineralized water (pH of demin water is within range). No leak of ion exchange chemicals! What makes this a bit strange is that the leak occurred in only one boiler while the others (same operation, same age, same maintenance schedule, same everything!) did not suffer from any leaks although fed with the same BFW. The BFW is of course treated with oxygen scavenger and neutralizing amine after the deaerator.
Thanks in advance.
