Different Types of Coal. It is important to be aware that coal can cover a variety of finished products of differing values and requiring different treatment. The main division is between coking coal and energy or steaming coal.Coking coals, used to make coke for use in blast furnaces, have particular properties which allow it to form a good coke when put through a coking process which involves heating in an atmosphere deficient in oxygen.t is important to be aware that coal can cover a variety of finished products of differing values and requiring different treatment.
