Types Of Combustion

TYPES OF COMBUSTION

High temperature exothermic chemical reaction between a fuel and an oxidant that produces oxidized gaseous products in a mixture called smoke, is a complicated sequence of elementary radical reactions. Solid fuel undergoes exothermic pyrolysis to produce gaseous fuels whose combustion then supplies the heat required to produce them. This experiment is hot enough that light either in glow or flame is produced.

This was the way how fire is explained in a science lab! 

In simple words,

Combustion is a chemical process in which a material reacts with oxygen present in the air to generate heat and light.

Now, if we look more deeper into it, there are mainly 3 types of combustion present namely,

Rapid Combustion, Spontaneous Combustion and Explosion,

Let's have a look at each of them, one by one, understand their work.

1) RAPID COMBUSTION

In rapid combustion, the combustible substance burn rapidly, producing heat and light when ignited externally. (Like a matchstick)!

2) SPONTANEOUS COMBUSTION

In spontaneous combustion, the combustible substances burst into flames immediately without the need for an external source. Substances which have a relatively lower ignition temperature generally burn by spontaneous combustion even at room temperatures! Like white phosphorus.

3) EXPLOSION

An explosion is a sudden chemical reaction which produces a large amount of heat, light and gas and is usually accompanied with a loud sound.

So, let's take some examples of these 3 combustions.

1) RAPID COMBUSTION

The immediate burning of cooking gas in a gas stove to give heat and light.

• The burning of kerosene oil in kerosene stove.
• Burning of wax in a candle etc.

2) SPONTANEOUS COMBUSTION

Burning of white phosphorus, sodium, potassium in air itself etc.

3) EXPLOSION

Bomb explosions, TNT, an overheated boiler or a simple tin can of beans tossed into a fire etc.

So, here's a short video above which explains all the types of combustion in an animated video.

So, that was the info. I hope you understood combustion and its types.

Thank you for reading.
