Boiler Safety and Role of Low Water Levels
Most of the boiler failures can be attributed to low water conditions. For safe boiler operations this must be kept under check. Low-water level conditions in the boiler occur when the water in the boiler drum falls below the low water level mark. Such conditions have the potential to severely damage the boiler.
