Flame rectification and physics behind it ( flame based diode )

Flame has a property that can be used to rectify AC voltage. Basically the flame can act as a diode, However the amount of current that can pass through the flame is rather small so it has limited application. One of the application of flame rectification is to detect if there is a flame or not. This can act as a safety device and can provide information if the burner has flame or not.
I will explain the physics behind flame rectification which is more or less similar to how vacuum diodes work.

Due to busy life during the past 40 days i could not make any videos. Must work on my channel and make new good videos. But anyway people do not watch so motivation is not that high.
