Difference between fuel and comburent

Fuel is that material that has the ability to release energy when it oxidizes violently in a reaction that releases heat, while an oxidizer is the substance that achieves combustion or accelerates it, it is responsible for oxidizing the fuel.

Fuel

It is that material that has the ability to release energy when it oxidizes violently in an exogenous reaction or with the release of heat. It consists of the release of an energy that is in potential form to use it directly as finished energy or mechanical energy.

The fuel leaves behind heat, carbon dioxide and other chemical compounds. Fuels can be solid, in this category coal, ture and wood are included. Combustive fuels such as diesel, gasoline and kerosene can also be found, as well as gaseous fuels such as liquefied petroleum gases or natural gas.

In the animal body, fuel is made up of carbohydrates, lipids and proteins, substances that provide energy by slow combustion for the body’s metabolism, muscle movement and growth. Substances used to produce a nuclear reaction in a fission process are also known as fuels, although the process is not combustion.

oxidising

It is known as an oxidizing agent and is a chemical compound that oxidizes another substance in oxidation-reduction reactions, where the oxidizing compound is reduced. The oxidant is the substance that achieves combustion or accelerates it, oxidizes the fuel to later be completely reduced.

The most common oxidant is atmospheric oxygen, which is found in the air in a proportion of approximately 21%. Most oxidizers contain oxygen, either in molecular form or as ozone, some acids and oxyacids give up oxygen during combustion. For combustion to occur, a minimum proportion of oxygen of between 5% and 15% is needed.

Difference between fuel and comburent

  • Fuel is that material that has the ability to release energy when violently oxidized during combustion.
  • The oxidant is an oxidizing substance that achieves combustion or accelerates it. Its function is to oxidize the fuel.
