Boiler Corrosion - an overview | ScienceDirect Topics

Lime or limestone has been added to coal for over 130 years to reduce boiler corrosion.The use of this system for full flue desulfurization was carefully studied in the 1920's and again after the last World War (Wickert, 1963, Kettner, 1965).Injection into the flame zone is convenient because the chemical can be premixed in the correct ratio before combustion.

10 Common Types of Corrosion

Crevice corrosion: Similar to pitting, crevice corrosion occurs at a specific location. This type of corrosion is often associated with a stagnant micro-environment, like those found under gaskets and washers and clamps. Acidic conditions or a depletion of oxygen in a crevice can lead to crevice corrosion.
