Mar 06, 2015· Coal, as it is commonly known, is a solid fossil hydrocarbon fuel material. The gross calorific value of coal is frequently used when determining the total calorific value for a specific amount of coal for fuel value purposes or when establishing the rank of classification of the coal material.
Calculation of GCV of fuel:-For calculation of GCV of fuel we need to analysis of fuel and get the constituent of fuel on weight basis. Based on the enthalpy of formation we may estimate calorific value of fuel. C+ O2 —- CO2 + 8137.5Kcal/kg of carbon. H2 +.5O2—-H20 + 28905 Kcal/Kg of hydrogen.
The service features the Indonesian Coal Index (ICI), the leading coal price reference used by Indonesian coal buyers and sellers, as well as the Indonesian government for spot trades, tax calculations, financial and investment analysis, strategic reporting and production planning. The ICI is also used to compute the Indonesian domestic coal price.

Oct 07, 2019· Fixed carbon is a measure of the amount of non-volatile carbon remaining in a coal sample. It is a calculated value determined from other parameters measured in a proximate analysis, rather than through direct measurement (ASTM method D3172-07a; American Society for Testing and Materials, 2013, p. 492-493).Fixed carbon is the calculated percentage of material that was lost during

Energy Content in Coal. The basic function of the power plant is to convert energy in coal to electricity. Therefore, the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of
