What are the consequences of low water levels in a boiler?

Low water levels in a boiler pose significant risks, primarily the potential for overheating and the risk of a boiler explosion. When water levels drop below the safe operating limit, the boiler tubes may become exposed to the combustion gases, leading to extreme temperatures. This overheating can cause the metal of the boiler to weaken, resulting in failures, such as tube rupture or even a catastrophic explosion, if the pressure builds up excessively without sufficient water to create steam or to cool the system.

Maintaining proper water levels is crucial for boiler safety and operational efficiency. Regular monitoring and appropriate controls are put in place to prevent such dangerous scenarios.
