can anyone explain the structure candle???? pls...

Let us now understand the structure of flames with the context of the flames of a candle. For this, you will need to closely observe the flames of an ordinary candle. You will notice its shape, the way it burns and most importantly the various colors of the flames.
When you light a candle a combustion reaction takes place with the wax of the candle which is the fuel and the air which contains oxygen. The flames are the are in which this combustion reaction is taking place. The release of heat and light energy from this exothermic reaction happens through the flame.
Now if you observe you will see three distinct colors in the flames. This helps us to classify the parts of a flame which are as following:
Inner Part: This is the innermost part of the flame. It is the part closest to the wick. You might assume that this is the hottest part of the flame. However, it is the least hot. This is the black part of the flames that contains unburnt particles of the carbon from the wick i.e. unburnt fuel.
Middle Part: This is the biggest part of the flame. The colors in this are varying shades of yellow and orange. This is the luminous flame because it emits light. This part is also not extremely hot. This is because this part gets a limited supply of oxygen. So incomplete combustion takes place here. Which is why it burns orange and is luminous.
Outer Part: Now this is the hottest part of the flame. This part has an unlimited supply of oxygen. So complete combustion takes place here. Hence it is the hottest part of the flame. Also, this part of the flames burns with a blue color. It is the non-luminous, i.e. does not emit light..
