Incomplete combustion will occur when there is not enough oxygen to allow the fuel to react completely to produce carbon dioxide and water.
It also happens when the combustion is quenched by a heat sink, such as a solid surface or flame trap.
Pyrolysis is the process of combustion in the absence of oxygen or burnt under controlled atmospheric oxygen.
Pyrolysis is an alternative to incineration, the method in which organic wastes are burnt inside incinerators.
The gases and liquids obtained by the process of pyrolysis can be used as fuels.
Combustion involves chemical reactions that are often highly exothermic.
Combustion systems utilize the energy of chemical compounds released during this reactive process for transportation, to generate electric power, or to provide heat for various applications.
