What happens if a water-cooled boiler loses its water?

When a water-cooled boiler loses its water, the primary concern is the risk of overheating and potential damage. Boiling water serves to absorb heat from the combustion process, allowing the boiler to operate safely and efficiently. If the water level drops too low, there is insufficient water to absorb the heat being generated, leading to a rapid increase in temperature of the boiler components.

This overheating can cause severe damage such as warped metal, and even catastrophic failure of the boiler. The materials that comprise the boiler are designed to operate within specific temperature ranges, and excessive heat can compromise their integrity. Thus, maintaining the proper water level is crucial to ensure safe operations and prevent costly repairs or unsafe conditions.

Choices that suggest the boiler would stop functioning immediately or that it would increase in efficiency or produce more steam do not accurately reflect what occurs in the event of water loss. Instead, the situation poses significant hazards that necessitate immediate attention and corrective action.
