The basic difference is that combustion is heating and no flames are produced whereas in burning most of the energy is converted to light energy and this results in less heat energy as compared to combustion.

Combustionis a chemical process in which a substance reacts rapidly with oxygen and gives off heat. The original substance is called the fuel, and the source of oxygen is called the oxidizer.

combustion refers to a process where a substance(termed--FUEL) reacts with oxygen to give out heat and light.
 in this case it is not necessary that a substance will undergo combustion to produce a flame. substances that vapourize, only produce flame  for  E.G. charcoal undergo combustion but instead of forming a flame it glows( as dry charcoal do not form any vapour).
WHEREAS 
when  in a combustion process a flame is produced it is referred to burning. for E.G. a lighted candle.
 here , it must be clear that only a fuel / combustible substance that vapourize form  a flame implying all vapourizing substances  do not produce a flame.
 hope this helps .

The basic difference is that combustion reaction is flame less but during burning flame is produced. 2. During combustion more amount of heat is produce compared to burning. Where as most of the energy in burning is in producing heat/light/sound. 3. Combustion mostly take place in hydrocarbons. Where as burning mostly take place in solid fuels.

Dear Student,
Please find below the solution to your problem.

In this case it is not necessary that a substance will undergo combustion to produce a flame.
Substances that vapourize, only produce flame for E.G. charcoal undergo combustion but instead of forming a flame it glows( as dry charcoal do not form any vapour).
Whereas when in a combustion process a flame is produced it is referred to burning. for E.G. a lighted candle.
Here , it must be clear that only a fuel / combustible substance that vapourize form a flame implying all vapourizing substances do not produce a flame.

Thanks and Regards
