Combustion

Combustion, abbreviated as COMB, is a chemical reaction between a fuel and an oxidizing agent, typically oxygen in the air, that produces heat and light.  In most cases, combustion involves the rapid oxidation of hydrocarbons, such as gasoline or natural gas, in the presence of oxygen to produce carbon dioxide, water, and other combustion products.  The heat released during combustion can be harnessed to produce energy, such as in the form of heat, mechanical work, or electrical power.  Combustion is the basis of many industrial processes, such as power generation, transportation, and manufacturing.

Combustion can be classified into different types based on the speed and completeness of the reaction.  Incomplete combustion, where the fuel is not completely oxidized, can produce harmful byproducts such as carbon monoxide, which is toxic to humans and animals. Complete combustion, where the fuel is fully oxidized, produces only carbon dioxide and water.  The efficiency of combustion processes can be improved by optimizing the fuel and air mixture, as well as the combustion temperature and pressure.  In some cases, combustion can also be enhanced by using additives or catalysts to promote more efficient reactions or to reduce harmful emissions.
