Internal treatment and control of boiler feed water | Hard

Boiler water treatment chemicals are therefore used for protecting a boiler plant from the problems and are applied for the whole systems including the feed water line and the steam condensate line. In case of internal boiler water treatment, chemicals are added to the boiler to prevent the formation of scale by converting the scale forming compounds to free flowing sludges, which can be
