CHAPTER 39 BOILER WATER TREATMENT
ssu.ac.irSome feed water treatment chemicals, such as chelants, if not properly applied, can corrode feed water piping, control valves, and even the boiler internals. While the elimination of oxygen from boiler feed water is the major step in controlling boiler corrosion, corrosion can still occur. An example is the direct
Boiler Water Treatment Part 2 – Internal Treatment
byworth.co.ukGenerally it is desirable to have a slightly high pH for boiler feed water. Ideally the feed water should be in the range of pH 8.5 – 9.5. This ensures that free carbon dioxide within the system becomes ‘fixed’. If copper fed lines or heaters are used, restrict the feed water pH to …
