What does "flame failure" detection involve?

Flame failure detection primarily focuses on ensuring that a flame is present where it is supposed to be during the combustion process in a boiler. This is crucial for safe operation, as the absence of a flame can lead to unburnt fuel accumulation, which poses significant safety hazards, including explosions or fire hazards.

Monitoring involves various methods to verify that the flame is ignited and stable, typically using flame sensors or photoelectric systems that can detect the characteristics of the flame. If the flame goes out unexpectedly, the detection system will trigger safety measures, such as shutting down the fuel supply to prevent further hazards.

By emphasizing the need for continuous monitoring of the flame, this aspect of safety management in boilers highlights the critical importance of ensuring stable and controlled combustion conditions for efficient and safe operation.
