Question

Explain combustion and types of combustion

Answer 1

Answer:

One of the types of combustion is Complete Combustion. Complete combustion occurs in an unlimited supply of air, oxygen in particular. Also, complete combustion is also known as clean combustion. Here the hydrocarbon will burn out completely with the oxygen and leave only two byproducts, water, and carbon dioxide.

Answer 2

Answer:

your answer is here :

COMBUSTION

Burning of combustible substance or fuel , in the presence of oxygen is called Combustion .

Combustion releases heat & light energy .

types of combustion

let us now study about the difference types of combustion .

• Slow combustion

When a combustible material burns at a slow, or moderate rate , it's combustion is called slow combustion.

Slow combustion usually occurs when there is an insufficient supply air. Therefore, such a combustion never gets really completed. Burning cowdung cakes, wood, etc., are examples of slow combustion.

• Rapid combustion

When a combustible substance burns at a fast rate, its combustion is called rapid combustion. Gaseous fuels generally undergo rapid combustion .

Rapid combustion occurs when there is a sufficient supply of air . The Combustion, in such cases, is complete.

• Spontaneous combustion

When a combustible substance catches fire on its own, even at room temperature, its combusion is referred to as spontaneous combustion. A piece of white phosphorus, or a piece of sodium metal are observed to undergo spontaneous combustion when kept in air.

• Explosive combustion

When a mixture of a combustible material and air burns completely, in a very short span of time in a closed space, an explosive combustion can take place. The combustible material, in such a case, burns uncontrollably in free supply of air and releases a very large amount of heat. This often produces the sound of an 'explosion,

For example, when a cracker is ignited, a sudden and rapid reaction take place, as a result, there is an evolution of heat, light and sound energy. reaction accompanied by (an explosive) sound, is called explosion.
