Answer:
Explanation:
The main combustion products of burning of fuels are carbon dioxide ... Air required per kg carbon = 4.32× (C × 2.667 + (H×8- O) + S) ... As the volume ratio of air: oxygen is 1: 0.21.

The ratio of air required for complete combustion of carbon to carbon dioxide to that required for combustion to carbon monoxide is:
- In complete combustion, the reactant burns in oxygen and produces a limited number of products.
- During complete combustion carbon and hydrogen combine with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). During incomplete combustion part of the carbon is not completely oxidized producing soot or carbon monoxide (CO).
- Carbon monoxide (CO) plays a major role in the oxidation of hydrocarbons.
- During the combustion process, fuel will break down into CO before being oxidized into carbon dioxide (CO2).
- Air required per kg carbon = 4.32× (C × 2.667 + (H×8- O) + S) as the volume ratio of air: oxygen is 1: 0.21.
