calculation of coal gcv to ncv

1. Calculate the GCV of a coal sample if its LCV is 6767.45 cal/g and if it contains 5% hydrogen. (Latent heat of steam is 587 cal/g). Ans GCV 7031.6 cal/g. 2. The gross calorific value of a fuel containing 6% H was found to be 9804.6 Kcal/kg. Find the net calorific value if the latent heat of steam is 587 cal/g. Ans 9487.62 Kcal/Kg.

Biomass calorific value calculator - Gen Less tools

Simple calculator. Oven-dry woody biomass typically has a calorific value of 18-21 MJ per kg on a dry basis (this is the gross calorific value). Most fuels are not oven dry when burnt and the water in the wood must be evaporated, detracting from the extractable energy* (or net calorific value). Moisture or water content is the single biggest ...

(GCV), or higher heating value, measures the total (maximum) amount of heat that is produced by combustion, including latent heat before combustion or generated in the combustion process. The net calorific value (NCV), or lower heating value, ex-cludes this latent heat. Natural gas in international trade is usually measured on
