Corrosion in boilers - Lenntech

Corrosion is a relevant problem caused by water in boilers. Corrosion can be of widely varying origin and nature due to the action of dissolved oxygen, to corrosion currents set up as a result of heterogeneities on metal surfaces, or to the iron being directly attacked by the water.

Oxygen attack in boilers - Lenntech

Oxygen corrosion may be highly localized or may cover an extensive area. Oxygen attack is an electrochemical process that can be described by the following reactions: Anode: Fe è Fe 2+ + 2e -. Cathode: ½ O 2 + H 2 O + 2e - è 2 OH -. Overall: Fe + ½ O 2 + H 2 O è Fe (OH) 2. In this reaction a temperature rise provides enough additional

Oxygen attack in boilers - Lenntech

Oxygen attack in boilers. Without proper mechanical and chemical deaeration, oxygen in the feed water enters the boiler. Much is flashed off with the steam; the remainder can attack boiler metal. Oxygen in water produces pitting that is very severe because of its localized nature. Water containing ammonia, particularly in the presence of oxygen
