Three-drum boiler - Wikiped

Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships.They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.

What is the purpose of the steam drum on a water tub

3/26/2016 · The primary function of the steam drum is separate water from steam which prevents carryover of the condensate into to the steam header (phase separation).

Steam drum - Wikiped

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.

Boiler Steam drum internals and function - boilersinfo.c

Steam drum internals for typical type of boiler are shown. The internals include separation devices to assist in separating small droplets of boiler water from the steam. Boiler water in the steam will cause scaling of the superheater and steam turbines.Baffles, chevron types separators and demister pads are used to minimize boiler water carryover.
