  • Combustion refers to the process where a substance burns in the presence of Oxygen, giving off heat and light in the process.
  • You might have heard that certain substances are combustible whereas some are non-combustible. Combustible substances are simply those that undergo this process.
  • But isn՚t Oxygen the most abundant substance on Earth? Doesn՚t it combine with most of the elements? But surely, not all reactions can be said to be similar to this process. Even many people believe rusting of Iron is a similar process as rusting involves iron combining with oxygen giving off heat.
  • So, what differentiates combustion from similar processes? It is the spontaneity with which substances react with Oxygen which defines a reaction.

Combustion Reaction: Types of Combustion and Combustion Fuels

Complete Combustion

During complete combustion, the reactant burns in oxygen and produces products that are limited.

  • Incomplete Combustion.
  • Smoldering.
  • Rapid Combustion.
  • Spontaneous combustion.
  • Turbulent combustion.
  • Micro-combustion.

Examples of Combustion

  • When substances react spontaneously with Oxygen giving off heat and light, the heat released fuels the process further making the reaction violent and rapid. If nothing is done to control this process, it takes the shape of a fire. It is this spontaneous and violent nature that distinguishes combustion from other similar processes taking place in the presence of Oxygen.
  • Some of the examples of combustion are
    • Burning of sulfur in the air
    • An explosion of hydrogen in air
    • Burning of Wax candle
    • Combustion of petrol in a car՚s engine
    • Burning of natural gas in a Bunsen burner
    • A bushfire means wood cellulose and other fuels burn in oxygen
  • The burning of methane, the main ingredient of natural gas, is an example of a normal reaction to burning. Stoves and furnaces operating on natural gas have a pilot light or a spark to provide the initial energy required to trigger the combustion reaction.
  • Magnesium burning does not emit carbon dioxide or water vapor, but it is also a combustion process since it is an exothermic reaction of a fuel substance with oxygen. Placing magnesium in the air is not enough to start burning, but a spark or flame splits the bonds between oxygen molecules in the air to allow the reaction to continue.

Types of Combustion

  • Let us now study the types of such reactions.
    • Complete combustion: When the reaction takes place in the presence of abundant Oxygen, the substances combine with Oxygen to their maximum extent. Such reactions have heat and light as a visible by-product.
    • Incomplete combustion: These are defined as the reactions that occur in the absence of sufficient oxygen because of which substances are unable to burn completely. Such reactions leave Soot in the container due to this process along with the formation of Carbon monoxide which is an air pollutant.
  • Apart from classifications based on the availability of Oxygen, reactions are also categorized based on their spontaneity and rate of reaction. Reactions that proceed violently can either lead to fire or even explosion (which is also accompanied by loud noise) . Formation of rust can also be categorized under slow combustion.


What is Combustion Example?


Combustion reactions occur as oxygen reacts with another element and emits heat and light. The burning of sulfur, natural gas, and sparklers are also typical forms of combustion reactions. Essentially, any reaction that involves burning it is a reaction of combustion.

What Type of Reaction is Combustion?


The process of combustion is a process in which the material reacts with oxygen dioxide, releasing energy in the form of light and heat. Combustion reactions must require as a single reactant. Hydrogen gas combustion produces hydrogen vapor. Remember that this reaction is often described as a mixture reaction.

What Are the Types of Combustion?


The three important types of combustion are:

  • Rapid combustion.
  • Spontaneous combustion.
  • Explosive combustion.

How Many Types of Combustion Air Are There?


There are two types of combustion air: Dedicated combustion air, such as air piped directly into a furnace, is air supply just for that appliance. It՚s sometimes called direct vent or sealed combustion.

What Are Five Examples of Combustion?


Examples of Combustion

  • Burning of Wood or Coal to heat your home.
  • Burning of Petrol or Diesel to run your Car.
  • Combustion of Natural Gas or LPG to cook for on your stovetop.
  • For the production of energy in thermal power plants.
  • Fireworks.
