The higher the hydrogen content of a fuel, the greater the discrepancy. Forecourt diesel's GCV is 6.3% higher than its NCV; for natural gas the difference is 10.8%. To convert kWh quantities based on NCV to their GCV equivalent you need to multiply by the following factors: Aviation Spirit 1.053 Aviation Turbine Fuel 1.053 Burning Oil 1.053
• for coal and oil, the NCV is about 5 % less than the GCV • for most natural and manufactured gas, the NCV is about 10 % less o Where fuel characteristics (moisture, hydrogen and oxygen contents) are known, the 2006 IPCC Guidelines give a more precise method to convert GCV to NCV data: NCV = GCV − 0.212H − 0.0245M − 0.008Y

During combustion, water vapor is produced as a byproduct. The latent heat of vaporization is the energy required to convert this water vapor back into liquid water. The Higher Calorific Value includes this latent heat, assuming that the water vapor is in a liquid state. Mathematically, the Higher Calorific Value (HCV or GCV) is calculated as ...
The GCV is a parameter that plays a major role in the design and safety of power plants. As a result, numerous researchers have created models to estimate the GCV based on simpler variables like proximate and ultimate compositions (van Aarde 2019). Some of these models were made for particular coal kinds from different geographical ...

Difference between Gross calorific value (GCV) and Net calorific value (NCV) Gross calorific value (GCV) assumes all vapour produced during the combustion process is fully condensed. It is the total amount of heat produced, when unit …
However a part of the heat energy in the fuel is also used to convert the moisture in fuel to vapor. This part of the energy of the fuel is not taken into account while measuring the NCV but is captured in the GCV. Thus GCV is also called the Higher Heating Value (HHV) and NCV is called the Lower Heating Value (LHV).
the simplified determination of the NCV through the measure of C. On the base of (3) it is possible to cal-culate NCV beginning from GCV and from the knowl-edge of the element composition [CEN/TS 14918:2005].
