Question

Why dried coal sample is taken for calculation of volatile matter

Answer 1

Volatile matter is a key parameter to determine the quality of solid fuel materials like coal and other coke-based materials.

The resultant ash is used for the calculation of the ash load and for material balance purposes while using boiler systems in industries.

It is also used for the ultimate analysis calculation of oxygen by difference.

The volatile matter also represents the yield of coke in the carbonization process which is important to provide data on the combustion properties of materials. This is important for selling and procuring of solid fuel materials.
