Proximate analysis of coal involves determining its various components by examining its fundamental properties. It includes the assessment of moisture content, volatile matter, fixed carbon, and ash content. Moisture content refers to the water present within the coal, which affects its combustion efficiency and transportation costs. Volatile matter represents the gases and vapours released when coal is heated, influencing its ignition and combustion characteristics. Fixed carbon denotes the solid carbonaceous residue remaining after volatile matter is expelled, indicating the coal’s heating value and combustion potential. Ash content signifies the inorganic residue left behind after complete combustion, impacting the coal’s purity and environmental implications. Proximate analysis offers valuable insights into the quality, usability, and suitability of coal for various industrial applications, energy generation, and environmental considerations.
