There are three types of combustion
1) Rapid combustion:- Gas burns rapidly and produces heat and light.Such combustion is called rapid combustion...
2) Spontaneous combustion:- The type of combustion in which a materials suddenly burst into flames, without the application of any apparent cause is called spontaneous combustion...
3) Explosion :- A large amount of gas formed in the reaction is liberation. Such a reaction is called explosion.

Types of Combustion:

1. Complete Combustion:
In complete combustion, a fuel reacts with oxygen to produce carbon dioxide, water, and heat. This is the ideal type of combustion where the fuel is burned completely, resulting in maximum energy release. The reaction products are environmentally friendly as they do not produce harmful pollutants.

2. Incomplete Combustion:
Incomplete combustion occurs when a fuel burns in a limited supply of oxygen, leading to the production of carbon monoxide, carbon particles, and water. This type of combustion is less efficient and can release harmful pollutants such as carbon monoxide, which is a poisonous gas.

3. Rapid Combustion:
Rapid combustion is a type of combustion that occurs at a fast rate, resulting in a sudden release of energy and heat. This type of combustion is often associated with explosions and can be dangerous if not controlled properly.

4. Spontaneous Combustion:
Spontaneous combustion is a type of combustion that occurs without the need for an external ignition source. It is usually caused by self-heating of materials such as oily rags or coal dust, which can ignite spontaneously under the right conditions.

5. Controlled Combustion:
Controlled combustion involves carefully regulating the supply of fuel and oxygen to ensure efficient and safe combustion. This type of combustion is commonly used in engines, furnaces, and other industrial processes to generate heat and energy.
Each type of combustion has its own characteristics and implications, and understanding these differences is important in various applications of combustion processes.
