Conversion Factors | SEAI Statistics | SEAI
Conversion factors are termed the "calorific value" or "heating value" of fuels. Definitions of energy units (toe and J) appear above, while the description of net calorific values (NCV) appears below the table. Gross calorific value (GCV) is determined by bringing all the products of combustion back to the original precombustion temperature ...

· The NCV values of coal are derived from experimentally determined Gross Calorific Value (GCV) and the available hydrogen content of coal using the formula, : (2) NCV = GCV53 H where H is the available hydrogen content of coal which accounts for the total hydrogen including those associated with the moisture.
Fuels
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 EUROPEAN UNION OF THE NATURAL GAS INDUSTRY .
(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, excludes this latent heat. Natural gas in international trade is usually measured on
What is the difference between gross and net calorific ...
Net Calorific Value (NCV) also known as lower heating value (LHV) or lower calorific value (LCV) is determined by subtracting the heat of vaporization of the water vapour from the higher heating value. This treats any H 2 0 formed as a vapor. Natural gas prices are decided on the basis of GCV and NCV.
