Stoichiometric or Theoretical Combustion is the ideal combustion process where fuel is burned completely. A complete combustion is a process burning all the carbon (C) to (CO 2), all the hydrogen (H) to (H 2 O) and all the sulphur (S) to (SO 2).

Stoichiometric combustion is by thermodynamic definition the theoretical combustion of every drop of fuel when mixed with the correct amount of air (a basic mixture of oxygen and nitrogen gases) to yield exhaust products of only CO 2 and H 2 O.

The Stoichiometric Ratio is the ratio of oxygen to fuel that is required to complete perfect combustion with no unused fuel or oxygen = 0% XS Air. Methane with 0% excess air as the oxidizer

Stoichiometric combustion occurs when all the oxygen is consumed in the reaction, and there is no molecular oxygen(O2) in the products. If the equivalence ratio is equal to one, the combustion is stoichiometric.

A fuel-air mixture is called stoichiometric, if the fuel-to-oxygen ratio is such that both are entirely consumed when combustion to CO 2 and H 2 O is completed. For example, the global reaction describing the combustion of a single component hydrocarbon fuel C m H n (subscript F for fuel) the stoichiometric coefficients are

1 day ago · Table 1- Stoichiometric coefficients of combustion reaction. Therefore, to completely combust one mole of a hydrocarbon fuel with a specified chemical formula, (x + y/4) × 4.76 moles of air are required. This corresponds to 100% stoichiometric air. However, in practice, complete combustion occurs when the amount of air supplied is slightly ...

Apr 4, 2022 · Stoichiometric combustion is a theoretical point where optimum oxygen and fuel mix levels achieve maximum combustion efficiency for industrial boilers. It is essential to introduce air into the combustion chamber to achieve complete combustion.

In the simplest combustion process, known as Stoichiometric Combustion, all the carbon in the fuel forms carbon dioxide (CO 2) and all the hydrogen forms water (H 2 O) in the products, thus we can write the chemical reaction as follows: where z is known as the stoichiometric coefficient for the oxidizer (air)
