Exploin the three types
of combustion.
Answers
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.
The three important types of combustion are:
- Rapid combustion.
- Spontaneous combustion.
- Explosive combustion.
1) Rapid Combustion:
Another type of combustion is Rapid Combustion. Rapid energy needs external heat energy for the reaction to occur. The combustion produces a large amount of heat and light energy and does so rapidly. The combustion will carry on as long as the fuel is available.
- An example is when you light a candle. The heat energy is provided when we light the candle with a matchstick. And it will carry on till the wax burns out. Hence it is a rapid combustion
2)Spontaneous Combustion:
As the name suggests the combustion occurs spontaneously. This means that it requires no external energy for the combustion to start. It happens due to self-heating. A substance with low-ignition temperatures gets heated and this heat is unable to escape.
- The temperature rises above ignition point and in the presence of sufficient oxygen combustion will happen. The reaction of alkali metals with water is an example.
3) Explosive Combustion:
Explosive Combustion happens when the reaction occurs very rapidly. The reaction occurs when something ignites to produce heat, light and sound energy, The simple way to describe is it to call it an explosion. Some classic examples are firecrackers or blowing up of dynamite.

Three types of combustion -
•Rapid Combustion
•Spontaneous Combustion
•Explosion
*** RAPID COMBUSTION - is a form of combustion in which large amounts of heat and light energy are released.
eg: immediate burning of cooking gas
*** SPONTANEOUS COMBUSTION - The type of combustion in which a material suddenly bursts into flames, without the application of any apparent cause is called spontaneous combustion.
***EXPLOSION - A large amount of gas formed in the reaction is liberated. Such a reaction is called explosion.
