Ash and total moisture ranked as second and third importance variables (respectively) that negatively correlated with GCV. Increasing ash resulted in a lower coal organic content (lower carbon percentage) which reduces the heating value, and growing the moisture content weakens the coal structure and decreases the GCV of samples (negative ...
With the growing popularity of empirical equations for estimation of GCV of solid fuels, there is a need to develop reliable and suitable models for the prediction of GCV of coal from the South ...

Sulfur Determination in Coal and Coke Introduction Total sulfur value is an important characterization measurement for coal and coke fuel materials and is considered to be part of the ultimate analysis parameters (determination of carbon, hydrogen, nitrogen, sulfur, and ash with oxygen calculation by difference). The total sulfur value is a primary
Determining the Gross Calorific Value in Coal. 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.
This document specifies a method for the determination of the gross calorific value of a solid mineral fuel at constant volume and at the reference temperature of 25 °C in a combustion vessel calorimeter calibrated by combustion of certified benzoic acid. The result obtained is the gross calorific value of the analysis sample at constant ...
