CHAPTER-6 COMBUSTION &FLAME
• Combustion-Types
• Conditions necessary for
combustion
• Fire extinguisher
• Flame
• Fuels characteristics
,
,Different Types of Combustion:
1. Rapid Combustion
In this type of combustion, the substances burns rapidly and yield light and
heat.
Example: Bring a burning matchstick or a gas lighter near a gas stove in
the kitchen. Turn on the knob of the gas stove. We find that the gas burns
rapidly and produces heat and light.
, 2. Spontaneous Combustion:
In this type of combustion, substances burst out into flames suddenly without any
known reason.
Examples: Many disastrous fires in coal mines result due to this kind of
combustion. The heat rays coming from the sun or a lightning strike might be
responsible for this kind of combustion.
