The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions.
The EN 590 had been introduced along with the European emission standards.With each of its revisions the EN 590 had been adapted to lower the sulphur content of diesel fuel – since 2007 this is called ultra-low-sulphur diesel as the former function of sulphur as a lubricant is absent (and needs to be replaced by additives).
Marine diesel oil (MDO) is a type of distillate diesel oil.Marine diesel oil is also called distillate marine diesel. [1] MDO is widely used by medium speed and medium/high speed marine diesel engines.
Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...
These are somewhat ideal values and the actual heat realized by any fuel will depend on the fireplace or combustion chamber used and its design for example. However they do give a useful guide to the heat available from any fuel. Dry wood has roughly two thirds the calorific value of coal so a greater weight is needed to make the same amount of ...

The Wobbe index is expressed in MJ/Nm³ (where 'Nm³' indicates'm³ in Normal conditions), or sometimes in BTU/scf.In the case of natural gas (molar mass 17 g/mol), the typical heating value is around 39 MJ/Nm³ (1,050 BTU/scf) and the specific gravity is approximately 0.59, giving a typical Wobbe index of 51 MJ/Nm³ (1,367 BTU/scf).
