Feed boiler corrosion

[arguellesmanuel]

what is the ideal pH for a feedwater boiler to work 150psig?

* The pH feed is behind 6.8 and 7.5 but in the boiler have pH 11 at 3 cycles. I can have problems in the future??

I feedind NaOH and my feed pH raise 9.2, but is not very high??

sulfites residuals is 30-60 ppm.


Thanks.
