Waterside Corrosion

Corrosion of metallic boiler surfaces, waterside, is due to Iron dissolving to form ions (Fe+). In this process,
the presence of any dissolved gas plays a major role, in particular oxygen and carbon dioxide. Often there
are corrosion phenomena with softened and demineralized water, which are by their nature aggressive
to iron (acid water with pH < 7): in these cases though clearly there will be no furring, corrosion remains
a risk and it will be necessary to condition the feedwater with corrosion inhibitors.

7.9.1 Heating boilers

Water treatment in a heating boiler is usually not a problem because the same water is used over and
over.  Treatment is primarily to eliminate corrosion and pitting cause by alkalinity and oxygen. It is usually
necessary to treat the water in a heating boiler once a year at the beginning of the heating season. TRIAD
recommends  you  consult  a  competent  water  consultant  to  determine  your  water  treatment.  The
appearance of scale, corrosion or pitting is definite evidence that water treatment is needed.

7.9.2 Water treatment guidelines

Get professional help

Detailed instructions for feedwater treatment should be prepared by a competent feedwater chemist
should be followed. Do not experiment with "homemade" treating methods or compounds.
Representative samples of feedwater and boiler water need to be analyzed frequently to ensure they are
within specifications.
