    What is coal?

    Coal is a sedimentary rock made predominantly of carbon that can be burned for fuel. Coal is readily combustible, black or brownish-black, and has a composition that, including inherent moisture, consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material.

    the coal Moisture held in chemically bonded form inside the coal is known as inherent moisture. Inherent moisture is not removed at low temperatures (100-120 oC), it gets released at higher temperature during the combustion of coal. It can be in the form of: • Decomposition moisture: water held within the coal's decomposed organic compounds

    Moisture. The coal when mined contains moisture. The moisture is in two forms. First is the inherent moisture which is entrapped within the structure of the coal. Second is the external moisture that is outside of the coal structure. The amount of moisture depends again on the geographical age, location and condition in the mines.
