Meaning of Combustion

What is Combustion:

Combustion means action and effect of burning or burning completely a certain matter. The word comes from the Latin combustion Y combustioni with the same meaning.

From a scientific point of view, combustion is described as a rapid oxidation process from which energy is released in the form of heat. This process may or may not generate light (flames).

Combustion is present in everyday life. For example, in the kitchen and fireplaces that use fire, in the mobilization of machinery and the automotive fleet (internal combustion engines), etc.

For combustion to be possible, the presence of specific factors is necessary: ​​a gasa oxidizing or oxidizing Y heat in high proportions.

The gas It is made up of matter that contains carbon and hydrogen. However, the fuel may eventually contain sulfur. Some known combustible materials are coal, natural gas, wood and petroleum derivatives such as gasoline, plastic, among others.

The substance oxidizing either oxidising It is usually oxygen, although not in its pure state, but in a proportion of 21% oxygen and 79% nitrogen, which is the basic composition of air. Also other substances can function as an oxidant. For example, fluorine.

As for the heat that triggers combustion, the temperature must reach a minimum degree of heating so that the fuel can react. This grade is named after flash point or flash point.

The amount of energy or heat that is released from combustion will depend on the qualities and characteristics of the materials in combustion, so that the results are variable.

Every combustion process generates products. The most important are: carbon dioxide, Coal Y water steam.

Combustion types

There are various types of combustion depending on the conditions of the oxidation process. Let’s see.

Complete or perfect combustion

It occurs when components are completely oxidized, resulting in the formation of carbon dioxide, liquid water, or sulfur dioxide.

incomplete combustion

Occurs when combustion is not absolute, but the oxidation of substances is partial and leaves unconsumed matter, which is called unburned. For example, carbon monoxide.

Stoichiometric combustion

It also receives the name of neutral combustion. It can only be produced artificially in scientific laboratories. In this type of combustion, a precise amount of air is used, in order to avoid the presence of oxygen in the resulting gases. It is said to be theoretical or ideal because some particles always persist.
