Does a steam boiler always need a low water cutoff?

A steam boiler does require a low water cutoff as a crucial safety feature to prevent the boiler from operating without adequate water levels. This component is designed to detect the water level within the boiler and will shut down the boiler if the water level falls below a predetermined safe point. Operating a steam boiler without sufficient water can lead to overheating, damage to the boiler, and potential safety hazards such as explosion or fire.

The regulation and standards governing steam boiler operation emphasize the necessity of low water cutoffs in almost all cases to ensure safe operation. This requirement helps to protect the equipment's integrity and the safety of those operating or near the boiler.

Therefore, the correct identification that a steam boiler always requires a low water cutoff reflects its fundamental role in maintaining safe operational conditions in accordance with industry standards and regulations.
