Hydrocarbons are molecules consisting of both hydrogen and carbon. The higher heating value (HHV) of a fuel is the amount of energy available from its complete combustion, including the energy from condensing the water vapor that results from the combustion. Chapter 11: Combustion (Thanks to David Bayless for his assistance in writing this section). The coefficients of the chemical equation show the relative amounts of substance needed for the reaction to occur. One common fuel is ethanol, C 2 H 5 OH, whose combustion equation is C 2 H 5 OH + 3O 2 → 2CO 2 + 3H 2 O If nitrogen is present in the original fuel, it is converted to N 2 , not to a nitrogen-oxygen compound.
