Scaling vs. Corrosion: Why It Matters for Your Boiler Feed

Aug 28, 2016 · What causes corrosion and why is it harmful to an industrial boiler? Corrosion in boilers, or the breakdown of the metal elements of the device, can happen for a variety of reasons. The most common reason is the presence of dissolved oxygen and carbon dioxide, which eat away at areas of the boiler causing system stress and cracking.
