Importance of Coal Characteristics for Effective Utilization of Coal

Coal is a heterogeneous rock with complex characteristics. Composition varies even in centimeters. Origin influences the composition of coal deposits, both organic and inorganic materials. The concentration of vitrinite or inertinite is determined by the nature and origin of the coal during the formation. Fluctuation and rates of down-warping or up-warping influence the accumulation of inorganic materials. The rank of the coal is determined by the thermal treatment undergone by the coal deposits over the period. Internal Moisture content depends upon the rank of the coal. Surface moisture content is based on the size of mined and crushed coal. Beneficiation of coal is a process of reducing the inorganic materials.
