Ignition temperature is the lowest temperature at which a substance catches fire. When a substance catches fire at a temperature lower than its ignition temperature is called combustion.
Types of Combustion:
1) Rapid combustion produces flame when a combustible substance is ignited. Example: Igniting a LPG.
2) When a combustible substances bursts in to flames without using of external agency is called Spontaneous combustion.

Ignition Temperature or Kindling Temperature :
The minimum temperature to which a combustible substance must be heated , before it catches fire is called Ignition Temperature.
Generally room temperature is considered as 25 degrees Celsius. If ignition temperature is less than average room temperature then :
---> The fuel will burn spontaneously [No external agent is required to burn the fuel]
---> This kind of combustion is known as Spontaneous Combustion.
Examples:
When a Phosphorous is left out in the open at room temperate for some time , it burns by itself.
Forest fires and coal mines are also example of spontaneous combustion.
