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.

Steam-water separation details
Primary steam-water separation removes nearly all the steam from the water so that very little steam is recirculated from the drum bottom towards the heated tubes through the outlet connection (downcomer).
At secondary separation, steam is passed through a secondary stage of separators or scrubber elements (usually closely spaced corrugated parallel plates) for final water droplet removal. Steam is then exhausted through various ports.
