16-A coal sample of GCV 4800 kcal/kg having total moisture 18%, then calculate the Net calorific value (NCV) of coal. NCV = GCV-(10.02 X Moisture) = 4800 – (10.02 X 18) = 4619.64 kcal/kg. …
WhatsApp: +86 18221755073The Proximate Analysis of any coal i.e. the % content of Moisture, Ash (A), Volatile Matter (VM), Fixed Carbon (FC) – also Sulphur (S) and Calorific Value (CV) – can be expressed on any of …
WhatsApp: +86 18221755073Net calorific value (NCV) can be calculated from gross calorific value (GCV) of coal using the formula: NCV = GCV - (0.09 * moisture content) for lignite and sub-bituminous coals, …
