Why flame failure cause in oil refinery heaters?

Flame failure in oil refinery heaters can occur due to several reasons, including insufficient fuel supply, malfunctioning burners, or improper air-fuel mixture. Additionally, equipment failures, such as faulty ignition systems or flame detectors, can contribute to the loss of flame. Environmental factors like high winds or changes in pressure can also impact combustion stability. Flame failure is critical to address promptly, as it can lead to unsafe operating conditions and potential explosions.
