Since water releases heat when it condenses, GCV is clearly bigger than NCV. What is GCV? The total amount of heat released when a fuel is burned. When fossil fuels are burned, the carbon and hydrogen in these fuels combine with oxygen in the air to produce carbon dioxide and water.

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], [20]: (2) NCV = GCV-53 H where H is the available hydrogen content of coal which accounts for the total hydrogen including those associated with the moisture.

GCV is clearly greater than NCV since water releases heat when it condenses. LPG vs Natural GasSummary of Key Differences. Because LPG has a higher calorific value (energy content), it takes less gas to generate the same amount of heat. The oxygen-to-gas ratio required for successful combustion is the second significant difference.

During combustion, one of the products is water vapor. The inclusion of water heat value distinguishes between gross (or high) calorific value (GCV) and net (or low) calorific value (NCV), where GCV includes the heat emitted by water vapor in condensation, whereas NCV does not includes [1], [2], [3].

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 ...

Although the leading order cost of NCV is the same as REML or GCV, the actual cost is higher because the dominant operations costs are in matrix-vector, rather than matrix-matrix, operations, so BLAS speed ups are small. However multi-core computing is worthwhile for NCV. See the option ncv.threads in gam.control. Author(s)
