Example: An example is burning of paper. Combustion. State. Complete combustion occurs when there is a lot of oxygen present. Complete combustion is a combustion process that takes place in the presence of inadequate air or oxygen. Airis composed ofoxygen, nitrogen, and small amounts ofcarbon dioxide, argon, and other trace species. Due to lack of oxygen, the fuel will not react completely. Carbon and hydrogen atoms in the hydrocarbon fuel react with oxygen in an exothermic reaction: carbon dioxide and water are produced. Combustion process takes place in a turbulent flow field. Complete Combustion: Also called "clean combustion," complete combustion is the oxidation of a hydrocarbon that produces only carbon dioxide and water.An example of clean combustion would be burning a wax candle: The heat from the flaming wick vaporizes the wax (a hydrocarbon), which in turn, reacts with oxygen in the air to release carbon dioxide and water. Combustion.
