This article will consider the difference between ignition temperature and fire point.

There are several methods and terms used for measuring the flammability and combustibility of a substance; Ignition temperature and fire point is one of them.

To understand the difference between ignition temperature and fire point, we must first understand the definition of the two (2) parameters.

What is ignition temperature:

Ignition temperature is also called autogenous ignition temperature or kindling point. As the name implies (autogenous), at this temperature, ignition source is not required to ignite; it is an auto process.

However, ignition temperature is the lowest temperature at which a volatile material will be vaporised into a gas which ignites without the help of any ignition source. The ignition temperature is different from flash point since as at flash point, ignition source will still be required to ignite.

What is a Fire point

This is the lowest temperature at which a volatile combustible substance continues to burn in air after its vapors have been ignited and the ignition source removed.

Difference between ignition temperature and fire point

Ignition Temperature Fire Point
1.    Its is concerned with the ignition process. Not concerned with the ignition process.
2.    It is autogenous It is not autogenous

I believe from the definitions and the tabular highlight, the difference between ignition temperature and the fire point is clear.
