The correction to the gross calorific value is 586 cal/g water (latent heat of steam = 586 cal/g). The water referred to is the weight of water produced by the complete combustion of unit weight of coal plus the water existing as moisture in the coal. The former is calculated from a known hydrogen content of the coal:
