What can happen if the water level in a boiler drops too low?

When the water level in a boiler drops too low, it can lead to overheating and potentially result in serious damage to the boiler. This occurs because the boiler relies on water to absorb heat produced by the combustion process. If the water level falls below a certain threshold, the metal components of the boiler can become exposed to the high temperatures, leading to overheating.

This overheating can cause the metal to warp or become brittle, potentially resulting in cracks or other structural failures. In severe cases, it may even lead to an explosion, posing risks not only to the equipment but also to personnel and surrounding areas. Thus, maintaining proper water levels is critical for safe and efficient boiler operation.
