ASME Standard Water Tube Boiler Steam Drum Made of SA516 Gr70 for Sugar Mill Boiler Replacement
Definition
The boiler steam drum is the most important pressure vessel in industrial boilers for storing hot water and steam. In an industrial boiler pipe system, not all hot water can be fully evaporated into steam, but rather, a mixture of steam and hot water. Because saturated hot water needs more heat for conversion into steam, a boiler steam drum is a required piece of equipment. The steam drum separates hot water and steam, where the mixture still flows back for reheating through a down comer.
A steam drum is a standard feature of a water-tube boiler. It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture. The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.
