Boilers
Water Treatment is the addition of chemicals to the boiler feed water. It serves to reduce the amount of oxygen to reduce corrosion capture contaminants and cause them to settle to the bottom without adhering to the metal surfaces. This allows greater periods between bottom tank cleanings.
Treatment reduces scaling on boiler tubes and piping. It optimizes tank cleanouts and:
- Prevents boiler tube internal metal loss due to corrosion.
- Prevents condensate piping corrosion and iron fouling of boiler tubes.
Scaling is a waterside phenomenon where solids contaminants (sludge) precipitate and adhere to the metal surfaces. The scale is an insulator, resulting in the reduction in heat transfer efficiency which:
- Causes hot spots in the metal where the scale is.
- Causes pitting and loss of metal under the scale.
