Fuels - Higher Calorific Values
Higher calorific values for some common fuels - coke, oil, wood, hydrogen and others

The calorific value of a fuel is the quantity of heat produced by its combustion - at constant pressure and under "normal" conditions (i.e. to 0oC and under a pressure of 1,013 mbar).
The combustion process generates water vapor and certain techniques may be used to recover the quantity of heat contained in this water vapor by condensing it.
The Higher Calorific Value (or Gross Calorific Value - GCV) suppose that the water of combustion is entirely condensed and that the heat contained in the water vapor is recovered.
The Lower Calorific Value (or Net Calorific Value - NCV) suppose that the products of combustion contains the water vapor and that the heat in the water vapor is not recovered.
