Clarification: For calculating the GCV of the coal use the formula GCV=w (T 2-T 1)/V, where w=weight of water and v=volume of fuel burnt. Substitute the corresponding values and we know that NCV is given by NCV=GCV – [(M/V)587], M is the weight of the water obtained by steam. 2. Calculate the HCV and NCV of the coal for the following data.

Empirical Relationship of GCV, UHV, and NCV UHV: Useful heat value = 8900 - 138(A+M) GCV. Gross Calorific Value = (UHV + 3645 M)/ NCV. Net Calorific Value = GCV - UHV, GCV, NCV in …
Coal Grades. The gradation of non-coking coal is based on Gross Calorific Value (GCV), the gradation of coking coal is based on ash content and for semi coking /weakly coking coal it is based on ash plus moisture content, as in vogue as per notification. Grades of Coking Coal. Swipe to view. Grade. Ash Content. Steel Grade - I. Not exceeding 15%.
The given values are for fuels with the given density. The variation in quality may give heating values within a range 5 -10% higher and lower than the given value. Also the solid fuels will have a similar quality variation for the different classes of fuel. 1 Btu (IT)/lb = MJ/t = J/kg = kcal/kg = kWh/kg.
· The Gross Calrific Value (GCV) is calculated in such a way that the products after combustion of a particular material are considered to be in their pre-combusted state.
