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).

Based on 27 weighings of the mass of burned gas, the real-gas GCV of methane is determined as H s (CH 4) = 890 202.1 J mol −1 with a confidence interval of ±52.6 J mol −1 (t 95% = 2.056). This value is by ΔH s /H s = (−0.0436 ± 0.0059)% below the real-gas GCV of H s (CH 4) = (890 590 ± 380) J mol −1 (k = 2) converted according to ...

Similar to GCV, NCV is typically measured in units of kilojoules per kilogram (kJ/kg) or British thermal units per pound (BTU/lb). NCV is particularly useful in applications where the heat generated is not fully utilized, such as in open fires or certain heating systems. By excluding the latent heat of vaporization, NCV provides a more ...
