The purpose of boiler water treatment is to protect the boiler and steam generation system against corrosion and scale formation and help to maintain steam purity and quality.
Preventing Boiler Scale Formation
Boiler scale control
Boiler scale is caused by the formation of insoluble salts of calcium and magnesium at high temperature. These form a rock-like coating on the boiler tubes which severely reduces the heat transfer.
This is highly undesirable, not only because it greatly reduces the efficiency of the boiler, but also causes the boiler tubes to overheat, so that in an extreme situation they can rupture with very hazardous consequences.
Scale formation is prevented by firstly removing as much hardness from the make-up water as possible (normally with a boiler water softener), and then secondly by dosing boiler water chemicals such as alkalinity builders, phosphate treatments and polymer sludge conditioners. These boiler treatment chemicals ensure that any hardness slippage is converted into a mobile sludge which can be removed by steam boiler blowdown and so doesn’t form boiler scale.
