Flame and its structure
It is the region of combustion of a combustible substance. The substances that vaporises during burning gives off flame. For instance, if a wire is brought near the flame of a burning candle, that portion near the flame becomes black due to deposition of unburnt carbon particles existing in the luminous zone of the flame. Similarly burning of wax and kerosene also vaporises during burning and hence produces flame. But on the other hand charcoal does not vaporise and hence does not produce flames on burning. The following figure shows the different layers of flame.
