Case histories in which boiler tube failures resulted from a combination of steam blanketing and underdeposit corrosion are reviewed. Steam blanketing originates from inadequate circulation and commonly occurs in horizontal or sloped boiler tube circuits in the root of a boiler. It can lead to boiler tube corrosion failures by providing a mechanism for concentration of normally soluble species at or above a liquid/vapor interface.
