    Apr 25, 2009 · The drums of bi-drum boilers can be anywhere near 100 tons. The boiler drums have large stubs welded, many instrument tapings, safety valve stubs, and internals to maintain the quality of steam and distribute the feed wate, and a facility to dose the chemicals uniformly across the length of the drum. Boiler drums are generally made of carbon steel of boiler quality plates of varying thickness depending on the design pressure of the boiler.Learn More

    The pressure at which the LP boiler is operated is a key parameter in reducing the risk of FAC damage. As pressure is decreased, an increase in fluid-mixture specific volume results in an increase in velocity. For natural circulation HRSGs, this is especially true in circuits between the upper half of the evaporator tubes and the steam drum.Learn More
