Carbon, hydrogen, and nitrogen determination is part of the ultimate analysis of coal fuel material, aiding in characterizing the material and providing information that can be utilized in calculating material/energy balances and efficiencies, as well as emission potentials for the coal fuel. The carbon, hydrogen, and nitrogen results for a coal material are also utilized to evaluate the reactivity potential for its use in a liquefaction or gasification process.

用力可AC600量热仪，苯甲酸为标样分析 The gross calorific value of coal, a solid fossil hydrocarbon fuel material, is most often used when calculating the total calorific value for a quantity of coal for fuel value purposes, or when determining the classification rank of the coal material. The gross calorific value and sulfur value of the coal material can also be used to calculate whether or not the coal material meets regulatory requirements for industrial fuel use.
