Demineralized Water Piping - Water treatment

2003-10-29 · Feed of oxygen scavenger and amines downstream of the deaerator "scrubber" section, that is, to the dearator storage section, is typically done to adjust water pH there, and to add amines for condensate pH/corrosion control (amines avaporate in boiler and "follow" steam to condensate lines). So, boiler feed water is DOWNSTREAM of the deaerator.

Scaling in boilers - Lenntech

Causes, and prevention of scaling in boilers, type of scaling. Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots.
