Scaling in Boiler might occur when water is evaporated into steam, leaving behind a more concentrated boiler water. Unfortunately, over time, the impurities in the water proliferate. Therefore, without proper chemical treatment and blow down, these impurities will eventually deposit as scale. Anti-scalant chemicals, sludge dispersant, and pH control agents help inhibit the effects of scaling in boiler tubes.
Corrosion is an irreversible electro-chemical reaction by which metal is destroyed by the dissolved oxygen that might be present in the feed, steam, and boiler water line.
Deaerator equipment help remove dissolved gases from the boiler water.
Chemical treatment with oxygen scavenger and condensate conditioners effectively prevent corrosion by removing the dissolved gases that cause corrosion.
