Boiler Safety and Role of Low Water Levels

The strength of steel drops sharply at temperatures above 800°F (480°C). Hence, a Low-water condition has the potential to melt the steel tubes. 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.
