Answer:
Combustion is the act of burning, in which fuel, heat and oxygen release energy. There are several types of combustion, such as internal combustion, diesel combustion, low temperature combustion and other novel forms.
Explanation:
types of combustion -
Complete combustion: During complete combustion, the reactant burns in oxygen and produces products that are limited
.Incomplete Combustion:
This combustion takes place when there doesn’t exist enough oxygen, allowing fuel to react completely producing carbon dioxide and water. This combustion is the same as complete combustion, it also produces water, but instead of carbon dioxide, the product is carbon and carbon monoxide. In this type of combustion, products which are pyrolysis remains unburnt and contaminate the resulted smoke with noxious gases.
3.Smoldering:
This form of combustion is slow, flameless and a low-temperature combustion, undergone by the heat evolved when the surface of the fuel is directly attacked by oxygen. Typically, it is an incomplete form of the combustion reaction. Solid materials that undergo smoldering combustion includes materials like coal, cellulose, cotton, tobacco, wood, foams etc.
4.Rapid Combustion:
Rapid combustion otherwise known as fire is a type of reaction which releases a large amount of heat and light and results in a flame often. This reaction is used in the form of machinery like internal combustion engines and thermobaric weapons. This combustion is intermittently known as explosion combustion.
5.Spontaneous combustion:
It is a type of combustion that occurs through self-healing, pursued by thermal runaway and then, finally ignition. Example, phosphorous ignites on itself at room temperature without heat application.
6.Turbulent combustion:
Combustion that results in a turbulent flame is mostly utilized for industrial applications as the turbulence helps in fuels and oxidizer mixing process.
7. Micro-combustion:
Micro combustion is combustions whose combustion processes take place in very small volumes. The high ratio of surface-to-volume increases loss of heat.
