Condensate Water Treatment to Prevent Steam Boiler Pipes

Neutralizing amines are used in boiler water treatment to control condensate return line corrosion. The amines do not have any adverse effects on copper or copper alloys under normal treatment conditions where pH is maintained between 7.5 to 9.0 and where only a few ppm of amine are continuously added to the boiler water.

Boiler feedwater and its treatment - Forbes Marshall

Feed water composition. In order to generate steam on a constant basis, boiler should be continuously supplied with water, called as feed water. Feed water consists of condensate, which gets collected after the steam gets condensed by losing heat to the process or radiation losses, flash steam and make up water.

Boiler Water Treatment Guidelines; Columbia Boiler Co

Use proper water treatment to prevent the buildup of scale on the boiler. After scale has built up on the walls of the boiler it is almost impossible to remove it from the boiler. The introduction of acids in the pressure vessel is thoroughly discouraged, since virtually any solution that will chemically attack the scale will also attack the boiler metal.
