Boiler Safety and Role of Low Water Levels

Boiler Safety and Role of Low Water Levels. 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. This is because of the
