: Is anyone out there having trouble with economizer tube leaks in their HRSG boilers? If so, what is your theory of the cause of the problem?
Bet you money it is oxygen pitting.Don't waste your time fixing leaks get a new Economizer and fix the D.A make sure you have min 6 psi stm on tank and it is vented and add some sulfite keep at least 8 to 10 ppm in the tank and 30-60ppm in the boiler.
