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" feedwater is added.
