Boiler Feedwater Treatment (Part I): Why Water Treatment is

Corrosion may occur in the feedwater system as a result of low pH water and the presence of dissolved oxygen and carbon dioxide. Corrosion in the boiler itself normally occurs when boiler water alkalinity is too low or too high or when the metal is exposed to oxygen-bearing water during either operation or idle periods.

Oxygen-diffusion corrosion in radiant heating systems

Jun 23, 2014 · Oxygen won’t usually damage a cast iron or steel boiler because most of these boilers have relatively large passages. The flow of water, however, will carry away the sludge and dump it in places you never even knew your system had, and that’s why oxygen-diffusion corrosion is something you need to avoid.

Choosing The Best Oxygen Scavenger for Your Boiler System

Although a properly operated deaerator can effectively remove oxygen to as low as 5 ppb, that level is still enough to cause significant damage in a boiler system. Chemical oxygen scavengers are therefore used to remove or "polish" these small amounts of oxygen remaining after the bulk of the oxygen has been removed through physical means.
