What is the primary function of an interrupted pilot?

The primary function of an interrupted pilot is to complete a trial and extinguish after the main flame is established. This means that the interrupted pilot is designed to provide ignition for the main burner during a startup phase. Once the main flame is successfully established and stabilized, the interrupted pilot automatically extinguishes itself. This design allows for efficient operation by ensuring that the pilot light is only active when necessary, reducing fuel consumption and improving safety.

When the main burner ignites, the interrupted pilot serves its function of initiating combustion. However, it is not required to stay lit continuously, contrasting with other types of pilots that must remain on. This mechanism helps in environments where energy efficiency is priority and minimizes the risks associated with continuously burning flames when they are not needed.
