Colder feedwater in the steam drum replaces the water that rises, thus creating a natural circulation of water. Low-water level conditions have the potential to severely damage the boiler. The furnace temperatures usually exceed 1,800°F (980°C) and the only thing that allows a boiler to withstand these furnace temperatures is the presence of water in all tubes of the furnace at all times

Water Handbook - Boiler System Failures | SUEZ

In some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler start-up.
