The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under "normal" (standard) conditions (i.e. to 0 o C 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.
