The Analysis Moisture is used to calculate from adb to db and back again ... TM usually does not have a big influence and therefore, the GCV arb has few questions associated with it. However, the GCV adb takes the Analysis Moisture into account which actually depends on the lab conditions (temperature, humidity, air pressure, etc.) which …

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 …

Moist, mineral-matter-free basis: For some low-rank coals, this basis is used to calculate calorific value. It uses a theoretical base as if there were no mineral matter, but includes the moisture content of the coal sample. For this basis, a calculation is needed to determine mineral-matter content rather than ash yield (see Parr formula above

of the water vapour produced during the combustion process. Gross calorific value (GCV) assumes all vapour produced during the combustion process is fully condensed. Net calorific value (NCV) assumes the water leaves with the combustion products without fully being condensed. Fuels should be compared based on the net calorific value.
