What is the function of a safety interlock in boiler operations?

The function of a safety interlock in boiler operations is to prevent the boiler from operating unless specific safety conditions are satisfied. Safety interlocks are critical components that ensure the safe operation of a boiler by monitoring various parameters and preventing the system from functioning in unsafe conditions. For example, they may check for low water levels, proper pressure levels, or the correct functioning of safety devices such as pressure relief valves.

If any of these conditions are not met, the safety interlock will disable the boiler from starting or will shut it down if it is already running. This mechanism is essential for protecting both the equipment and personnel from potential hazards associated with boiler failures, such as explosions or leaks, thus ensuring overall safety in boiler operations.
