Rapid combustion
The combustion reaction in which a large amount of heat and light are produced in a short time is called rapid combustion.
For Ex:
1)The immediate burning of cooking gas in a gas stove to give heat and light.
2)The burning of kerosene oil in kerosene stove.
3)Burning of wax in a candle
Spontaneous combustion
The combustion reaction which occur on its own(without the help of any external heat)is called Spontaneous combustion.It place at room temperature.The heat required for spontaneous combustion is produced inside the substance by its slow oxidation.
Spontaneous combustion take place at room temperature.The heat required for spontaneous combustion is produced inside the substance by its slow oxidation.It is usually undergone by those substances which have quite low ignition temperature.
For Ex:
1)The burning of White phosphorus on its own at room temperature is an example of spontaneous combustion.
2)The spontaneous combustion of coal dust has resulted in many disastrous fires in coal mines.
3)Forest fire can also be started by spontaneous combustion reaction due to the heat of the sun or due to spark of lightning from the sky.
4)Spontaneous combustion of straw and forest wood take place leading to forest fires.
The combustion reactions which take place slowly and give less amount of heat slowly are termed as slow combustion reactions.
The processes of rusting, digestion of food are few examples for slow combustion.

Hey mate here is your answer
1. Slow combustion- when a combustible material burns at a slow or moderate rate, its combustion is called slow combustion.
2. Rapid combustion- when are combustible substance burns at a fast rate, it's combustion is called rapid combustion.
3. Spontaneous combustion- when a combustible substance catches fire on its own, even at room temperature, it's combustion is referred to as spontaneous combustion.
