Water Treatment
Boiler Water Treatment: The Chemistry Behind Every Steam Bill
A boiler concentrates feed-water impurities relentlessly: what enters as harmless hardness leaves as insulating scale on heat-transfer surfaces. One millimetre of scale can raise fuel consumption 5–8%, and localised overheating under scale is how tubes fail.
The core program
External softening removes most hardness; internal treatment finishes the job. Phosphate conditioning precipitates residual hardness as removable sludge; polymer dispersants keep it mobile for blowdown; oxygen scavengers (catalysed sulphite for most industrial boilers) stop pitting corrosion in the boiler and condensate system; amine treatment protects condensate lines from carbonic acid attack.
Tests that matter
Daily: feed and boiler water hardness, sulphite residual, pH/P-alkalinity, TDS or conductivity for blowdown control. Weekly: chloride cycles to verify blowdown maths. A logbook trend catches softener slippage a week before scale does.
JSM Traders supplies complete boiler treatment ranges — scavengers, phosphates, dispersants, amines — with dosing schedules sized to your boiler rating and feed-water quality.
Frequently Asked Questions
Softener slippage, condensate contamination or inadequate internal treatment — daily hardness and sulphite tests plus blowdown discipline catch it before the tubes pay.
