BOILER WATER TREATMENT
The treatment and conditioning of boiler feed water must satisfy three main objectives:
- Scaling and deposition prevention.
- Corrosion protection
- Production of high quality steam
External Treatment
Is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the boiler system in question. There are many types of external treatment (softening, de-silicization, de-alkalization, De-mineralization, De-aeration….etc) which can be used to tailor make feed-water for a particular system.
Internal Treatment
Chemical treatment of water inside the boiler is usually essential and complements external treatment by taking care of any impurities entering the boiler with the feed water (hardness, oxygen, silica, etc.).
The purpose of an internal treatment is to
- react with any feed-water hardness and prevent it from precipitating on the boiler metal as scale;
- condition any suspended matter such as hardness sludge or iron oxide in the boiler and make it non-adherent to the boiler metal;
- provide anti-foam protection to allow a reasonable concentration of dissolved and suspended solids in the boiler waaervengter without foam carry-over;
- eliminate oxygen from the water and provide enough alkalinity to prevent boiler corrosion.
