types of pulverized coal

Different Types of Coal Introduction underground COAL

The ability to blend different types of coal enables some coals which do not coke well to be used with higher grade coals to form an acceptable mix. Developments in blast furnace technology (pulverized coal injection in particular) have also allowed lower quality coals to be used in steelmaking in place of a portion of the coke.
