Following are the objectives of boiler water testing. 1. To prevent scale formation in the boiler. 2. To prevent corrosion in the boiler feed system by maintaining the boiler water’s alkaline condition. 3. To remove dissolved gases such as oxygen from water. 4. To control sludge formation, thus preventing carry over into the system. 5.
Boiler Water Treatment Oxygen scavengers are chemical additives fed to the boiler feed water or condensate return to remove residual dissolved oxygen. Corrosion and its deleterious effects cause numerous difficulties with materials being exposed to adverse effects.
Sep 26, 2016 · The most appropriate boiler feed water treatment system will help the facility avoid costly plant downtime , expensive maintenance fees, and boiler failure as a result of scaling, corrosion, and fouling of the boiler and downstream equipment.
What does a boiler feed water treatment system typically remove? Installing a water treatment system in place before a boiler feed system will remove dissolved and suspended solids as well as organic material that may be present in the feed water. - Calcium and magnesium: causes scaling of the boiler feed water.
