A burner photocell is a flame detection device used in industrial combustion systems. It senses light emitted by the burner flame and sends a signal to the burner control unit to confirm successful ignition.
If the flame is not detected during startup or is lost during operation, the photocell triggers the burner safety control to shut down fuel supply. This prevents unburned fuel accumulation and improves system safety.
Burner photocells are widely used in gas and oil burners installed in boilers, furnaces, ovens, and industrial heating systems. They provide fast and reliable flame monitoring for safe combustion processes.
