What does flame impingement refer to in heating systems?

Flame impingement refers to the phenomenon where the flame of a burner or heater directly contacts a surface or object. This contact can lead to localized heating that may result in overheating, damage to components, or reduced efficiency of the heating system. It is crucial in heating systems to keep flames properly contained and directed to prevent any undesirable effects that could compromise safety and performance.

In this context, the emphasis on flame striking against an object illustrates its potential impact on both the heating system and the object itself, highlighting the need for proper design and maintenance to avoid issues related to overheating and potential hazards.
