Corrosion will destroy condensate pipes and will generate corrosion products which will negatively affect the operation of the boiler system, especially if part of the condensate is recovered to be used as boiler feedwater.

Corrosivity - USGSThe consensus is that feedwater oxygen, iron, and copper content should be very low (e.g., less than 7 ppb oxygen, 20 ppb iron, and 15 ppb copper for a 900 psig boiler) and that pH should be maintained between 8.5 and 9.5 for system corrosion protection.Find Fast Results - Results Updated Today.Compact 40-95kW.

A typical AVT guideline is to maintain a pH of about 9.3–9.6 and the dissolved solids concentration to less than 2 ppm in the feedwater entering the boiler. The ammonia concentration typically ranges between 0.5 and 2 ppm as required to maintain the desired pH. 6 There are some inherent problems associated with using AVT.
