Question: 1 / 400

What can be a consequence of low water levels in a boiler?

Increased efficiency

Boiler overheating or explosion

Low water levels in a boiler can lead to significant operational issues, primarily overheating or even an explosion. When the water level drops below the safe operating level, the boiler's heating elements are exposed to high temperatures without the coolant effect of water to absorb heat. This can cause the metal components of the boiler to overheat, leading to thermal stress and potential failure of the boiler materials.

If overheating continues, it may result in the boiler's pressure relief devices being unable to cope with the increasing pressure, leading to a catastrophic failure or an explosion. This is a serious safety concern, which is why maintaining proper water levels in a boiler is critical for safe operation. Proper monitoring and management of water levels help ensure that the boiler remains within safe operational parameters, reducing the risk of dangerous situations.
