you need to convert the volume of the fuel into a mass – or have the NCV expressed in terms of volume. Usually, a step will be required to convert mass into volume and this is done by using a conversion parameter known as density that expresses the mass per a unit of volume (e.g. kg/m3). You can find some density values in Table 2, below.

EnconTips

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).

How do you convert ncv to gcv?

You can convert net calorific value (NCV) to gross calorific value (GCV) by using the formula: GCV = NCV + latent heat of vaporization of water (which is typically around 2440 kJ/kg).
