Boiler Steam drum internals and function - Boilersin

In the water tube boiler the upper drum (Boiler steam drum) provides for separation of steam from water. It also provides liquid holdup capacity (typically 10 to 60 seconds) to allow for a dynamic response to load changes without losing liquid in the downcomer and riser tubes.

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

Mar 25, 2016· The steam drum is primary used on water tube boilers and HRSGs. It contains internals such as the agglomerators and the cyclone separators, chevrons, demister pads, and any combination thereof. 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).
