Stoichiometric Combustion - Engineering ToolBox

The combustion process can be expressed: [C + H (fuel)] + [O 2 + N 2 (Air)] -> (Combustion Process) -> [CO 2 + H 2 O + N 2 (Heat)] where. C = Carbon. H = Hydrogen. O = Oxygen. N = Nitrogen. To determine the excess air or excess fuel for a combustion system we starts with the stoichiometric air-fuel ratio. The stoichiometric ratio is the perfect ideal fuel ratio where the chemical mixing proportion is correct.
