Fundamentals:

The combustion of a pure gas (e. g. methane) with air follows the specific stoichiometric reaction equation. For a gas mixture each component requires it's own separate reaction equation.

For a fixed fuel gas composition the oxygen needed for the stoichiometric combustion is computed by the reaction equations. The air and flue gas volumes are determined by a mass balance according to the ideal gas law.

Program features:

For a user-supplied fuel gas composition with up to 10 components, the program generates the combustion equations and calculates the stoichiometrically required air rate and resulting flue gas rate. For the actual air-to-fuel ratio the effective combustion air rate and flue gas composition (only main component) is then calculated. The case of incomplete combustion, i.e. when the air-to-fuel ratio < 1, is not considered.
