2019-10-7 · Coal Analysis. Most, if not all, coals are tested prior to being used. Some markets require specific quality characteristics for the process in which the coal is used, and environmental regulations also require knowledge of a coal’s quality. Some products also require analysis of physical characteristics of coals for handling or processing.

Coal Analysis | Applications - DDS Calorimeters
The CV is measured in MJ/Kg (KJ/g) or CAL/g or BTU/lb, the conversion factors are well known: 1 MJ/Kg = 429.92255 BTU/lb = 238.84586 CAL/g. For reference: 1J = 1Ws (1 Watt for 1 second) If the power station conversion efficiency from coal to electricity would be 100% then 1 gram of coal with a CV of 26KJ/g would result in 26000 WS = 7.2 Watt Hour.
