COAL
Coal is an important primary solid fuel, that has been formed as a
result of alteration of vegetable matter under some favourable conditions.
Coalification (or) Metamorphism
The process of conversion (or alteration) of vegetable matter to
anthracite (coal) is called coalification or metamorphism of coal.
1. Classification of Coal
Coal is classified on the basis of its rank. The rank of coal indicates its degree of maturity. Various types of coal are:
The progressive transformation of wood to anthracite results in
1. decrease in moisture content,
2. decrease in volatile content,
3. decrease in hydrogen, oxygen, nitrogen and sulphur contents,
4. increase in carbon content,
5. increase in hardness,
6. increase in calorific value.
