CHa + (1 + a/4) (O2+ 3,76 N2) --> CO2 + a/2 H2O + 3,76 (1 + a/4) N2

A  (1 + a/4) moles of oxygen1 mole of carbon dioxide and a/2 moles of water3.76 (1 + a/4) moles of nitrogen are also put into playend of combustion temperatureexact amount of oxidizernitrogen remains inertone mole of CHa fuelstoichiometric combustion is a combustion carried out with the  (1 + a/4) moles of oxygen1 mole of carbon dioxide and a/2 moles of water3.76 (1 + a/4) moles of nitrogen are also put into playend of combustion temperatureexact amount of oxidizernitrogen remains inertone mole of CHa fuelstoichiometric combustion allowing the fuel to be completely oxidized.

This is the one which leads to the highest  (1 + a/4) moles of oxygen1 mole of carbon dioxide and a/2 moles of water3.76 (1 + a/4) moles of nitrogen are also put into playend of combustion temperatureexact amount of oxidizernitrogen remains inertone mole of CHa fuelstoichiometric combustion.

This equation means that the stoichiometric combustion of  (1 + a/4) moles of oxygen1 mole of carbon dioxide and a/2 moles of water3.76 (1 + a/4) moles of nitrogen are also put into playend of combustion temperatureexact amount of oxidizernitrogen remains inertone mole of CHa fuelstoichiometric combustion requires  (1 + a/4) moles of oxygen1 mole of carbon dioxide and a/2 moles of water3.76 (1 + a/4) moles of nitrogen are also put into playend of combustion temperatureexact amount of oxidizernitrogen remains inertone mole of CHa fuelstoichiometric combustion and produces  (1 + a/4) moles of oxygen1 mole of carbon dioxide and a/2 moles of water3.76 (1 + a/4) moles of nitrogen are also put into playend of combustion temperatureexact amount of oxidizernitrogen remains inertone mole of CHa fuelstoichiometric combustion.

If the oxidizer is air,  (1 + a/4) moles of oxygen1 mole of carbon dioxide and a/2 moles of water3.76 (1 + a/4) moles of nitrogen are also put into playend of combustion temperatureexact amount of oxidizernitrogen remains inertone mole of CHa fuelstoichiometric combustion, but since they do not react with the fuel, they are found in the flue gases.

It is said that  (1 + a/4) moles of oxygen1 mole of carbon dioxide and a/2 moles of water3.76 (1 + a/4) moles of nitrogen are also put into playend of combustion temperatureexact amount of oxidizernitrogen remains inertone mole of CHa fuelstoichiometric combustion.
