boiler tube anti-wear scales

Boiler Tube Life Management

The most common cause of overheating and failure of boiler tubes is the formation of hard scale on the boiler tube surfaces. This is caused by calcium and magnesium in the boiler water. When untreated boiler water is heated, this calcium and magnesium will precipitate from the solution to form hard scale …

Finding the Root Cause of Boiler Tube Failures

What determines the frequency of chemical cleaning is the amount of scale and the rise in the tube metal temperature to the oxidation limit or design temperature. For the common boiler steels, the oxidation limits are: Carbon Steel (SA 178A, SA 210 Al) Carbon + 1/2 Mo (SA 209 Tl) - 1/2 Mo (SA 213 T-11) 11/4 Cr 1 Mo (SA 213 - T-22) 21/4Cr -

Scaling in boilers - Lenntech

Tubes developing mechanically weak/defective corrosion scales can experience enhanced wastage through the synergistic action of corrosion and erosion. Chlorine is almost invariably the active corrosion species. Sootblower erosion and/or local increases in flue gas velocity (fouling/blockages) can exacerbate metal loss.
