Gross calorific value (GCV) or Higher Heating Value (HCV) is the amount of heat released by the complete combustion of a unit of fuel. It assumes all water vapour produced during combustion process is fully condensed. Net Calorific Value (NCV) or lower heating value (LHV) or lower calorific value (LCV) is determined by subtracting the heat of ...

03/11/2016 · a) Higher percentage of C and H increases the calorific value of coal and hence better is the coal. b) Higher the percentage of O2 lower is the calorific value and lower is the coking power. Also O2 when combined with hydrogen in the coal, hydrogen available for combustion becomes unavailable.

Coal Tar Products Coal, like oil, is chemically a complex substance but unlike oil, it is somewhat deficient in hydrogen and rich in carbon. This not only makes for a lower heating value but also makes it more difficult to convert coal into clean liquid products than it is to refine into such products.
