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.

Coal Conversion Facts . WORLD COAL INSTITUTE [email protected] August 2007 Calorific Values (CV) Units: kcal/kg – kilocalories per kilogram MJ/kg* – Megajoules per kilogram Btu/lb – British thermal units per pound * 1 MJ/kg = 1 Gigajoule/tonne (GJ/t)

Chapter 2. Energy Balance Table

Unit and Conversion All entries in the EBT are expressed as one energy unit: kilocalorie (kcal), gigajoule (GJ), thousand ton of oil equivalent (ktoe), etc. Net calorific values (NCV) are generally used in building energy balances since most current technologies are still not able to recover

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 ...

Should the calorific values be changed from net to gross

For gases, these values are converted to NCV in the balance tables. In the IEA Annual Questionnaire both NCV and GCV are reported for coal, while renewables are reported in terms of NCV only. Additionally, classification of coals is done on a GCV basis. Calculations of …

2C+O2—-2C0 +2430 Kcal/kg of carbon This indicated loss of (8137.5 – 2430) = 5707.5 Kcal of heat per kg of carbon burnt in compared to carbon burnt with conversion as CO2. Hence CO generation must be avoided with calculated excess supply of oxygen for combustion.
