What is the purpose of a 'safety interlock' in boiler operation?

The purpose of a safety interlock in boiler operation is fundamentally to prevent the boiler from operating under unsafe conditions. This system is crucial for ensuring that the boiler cannot function if certain safety parameters are not met. For example, it can disable the boiler if pressure levels are too high, if there is insufficient water flow, or if there are other hazardous situations that could lead to malfunction or failure. By doing so, safety interlocks protect both the equipment and the personnel working in proximity to the boiler, reducing the risk of accidents or equipment damage.

While other systems in the boiler may adjust the water level or enhance fuel combustion, those functions are distinct from the role of a safety interlock. The interlock is primarily focused on maintaining safety standards and preventing operation when conditions are potentially dangerous, highlighting its importance in the overall management of boiler systems.
