How to Destroy a Boiler -- Part 1

The control of the boiler drum level is tricky and even the best tuned control systems cannot always prevent a low-water condition. The "water level" in a steam drum is actually a fairly unstable compressible mixture of water and steam bubbles that will shrink and swell with pressure changes and will actually shrink momentarily when more "cold

What Is A Water Tube Boiler And How Does It Work? | IQ Mech

Aug 27, 2021 · Steam Drum:-This reservoir plays a key role in a water tube boiler. This is the place where water or steam meets with each other. Generally, it stores the steam that is produced in the boiler and sends back water to the mud drum for reuse. So we can say that a steam drum in a boiler acts like a phase-separator.

Three-drum boiler

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.
