Boiler Safety and Role of Low Water Levels

Controlling the boiler drum level is complicated as the "water level" in a steam drum is actually a fairly unstable mixture of water and steam bubbles that shrinks and swells as the pressure changes. This is because of the fact that as the steam demand increases, the pressure in the boiler drops causing the water level to rise.
