Boiler interlocks ensure safe operation by preventing unsafe conditions through automated controls and safety mechanisms.

Low Water Level Interlock: Prevents boiler operation if water level is too low to avoid overheating.
High Pressure Interlock: Shuts down the boiler if pressure exceeds safe limits to prevent explosions.
Flame Failure Interlock: Stops fuel supply if the flame goes out, preventing unburned fuel accumulation.
Overtemperature Interlock: Triggers shutdown if the temperature exceeds preset limits to protect equipment.
