How much Air is Required for Complete Combustion? | Thermodynamics

The amount of air supplied to a boiler furnace is very great and so it cannot be measured directly. Its indirect measurement can be done if we know the volumetric analysis of dry flue gas. When we consider the volumetric analysis of flue gas we consider carbon monoxide, carbon dioxide, oxygen and nitrogen because the quantity of sulphur dioxide is negligible and water vapour is condensed.
