Steam drum - Wikipedia

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.

Mitsubishi Power | Drum Boilers

In a drum boiler, the circulation of water is produced through the density difference of water in the down comer pipe and the water/steam mixture in the furnace tubes. In low-pressure boilers where this density difference is large, the circulating force is high and a high volume of circulation can be ensured, but since it becomes difficult to
