How to Improve Feedwater Quality to Prevent Boiler Corrosion

27/4/2021 · To prevent corrosion, boiler water needs to be somewhat alkaline and not acidic. Improper acidity and slightly alkaline water can dissolve metal and the protective film on metal surfaces. Acidic attack occurs if the pH falls below 8.5. In this condition, materials are susceptible to surface thinning caused by etching.

Prevention of Corrosion and Scale Formation in Steam Boilers

Even chemicals used to prevent corrosion don't work as expected in these harsh conditions. Rust particles are transported through the system in the steam, so the corrosion is not limited to one area. The result is material abrasion throughout the whole system, reducing the life time of the boiler and the piping system.

The Effects of Corrosion in a Boiler | Chardon Labs

Pre-treatment of boiler water Given that carbonic acid is one of the main causes of steam condensate corrosion, then an obvious solution is to remove the carbon dioxide from the water before it enters into the steam boiler system in the first place. Dealkalisers used in conjunction with boiler water softeners can help to reduce the pH level of water entering the boiler. Reverse osmosis (RO) systems can both reduce alkalinity and remove other dissolved particles from the boiler feed-water. This allows the boiler to work more efficiently, saving you money on energy bills and volumes of water and any effluent. Corrosion …
