Description
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. The size of the steam drum is determined by the volume required for a clean separation between steam and water to produce a dry saturated steam, it also provides an adequate amount of steam storage. The steam drum is also called the upper drum.
