How does the process of combustion work?

Combustion is a chemical reaction that occurs between a fuel and an oxidizing agent, typically atmospheric oxygen, that results in the release of heat, light, and various combustion products. The process of combustion is fundamental to many aspects of human life, including the generation of energy for transportation and electricity, the heating of homes and buildings, and the cooking of food.

The three basic requirements for combustion are fuel, oxygen, and heat. In order for the reaction to take place, the fuel must be heated to its ignition temperature, at which point it reacts with oxygen to produce heat and light, as well as a variety of combustion products such as water, carbon dioxide, and nitrogen oxides. The specific products of combustion depend on the fuel being burned and the conditions under which the reaction occurs.

The rate at which combustion occurs depends on several factors, including the concentration of fuel and oxygen, the temperature of the reactants, and the availability of a catalyst to speed up the reaction. In addition, the nature of the fuel itself can affect combustion, with fuels such as coal and oil producing more complex and harmful combustion products than cleaner-burning fuels like natural gas.
