Answer / anindya
Both high and low pH can cause corrosion in boiler. In
acidic range the protective layer of
magnetite is not able to form and it cause corrosion. In
very high pH range the protective layer of
magnetite breaks down and this leads to caustic corrosion.
For corrosion prevention maintaining
proper pH and alkalinity is very important.
