2019-6-19 · Stress-Induced Corrosion. Certain portions of the boiler can be very susceptible to corrosion as a result of stress from mechanical forces applied during the manufacturing and fabrication processes. Damage is commonly visible in stressed components, such as rolled tube ends, threaded bolts, and cyclone separators.

2019-6-21 · Off-line boiler corrosion is usually caused by oxygen in-leakage. Low pH causes further corrosion. Low pH can result when oxygen reacts with iron to form hydroferric acid. This corrosion product, an acidic form of iron, forms at water-air interfaces. Corrosion also occurs in boiler feedwater and condensate systems.

In the Frasch industry, steam boiler corrosion was an important difficulty. Since 1500 gallons of water are needed to produce one ton of sulfur, it was necessary to develop sea water resistant steam plants before off shore mining became possible (Brogdon (U.S.P. 2,937,624, 1960; Axelrad, U.S.P. 2,947,690, 1960).

2019-5-23 · Boiler corrosion is the active destruction of sound boiler metal by the pitting action of dissolved oxygen in the boiler water. This usually results in deep holes in the metal which are self protected by further corrosion products ie scabs or blisters over the hole which allow the chemical reaction to continue.
