Adiabatic compression phenomenon

What are the characteristics of adiabatic compression ignition?

• Rapid compression, usually occurring in less than one second.
• A non-metallic material exposed near the dead end of a tube, itself having been subjected to rapid compression.
• A maximum compression temperature that exceeds the auto-ignition temperature of the non-metallic material.

The risk of ignition can be minimised by controlling heat sources and using materials that are difficult to ignite and do not sustain combustion in the final application environment.

Ignition occurs in an oxygen system when oxygen, fuel and energy combine to create a chemical reaction (fire triangle).

Although oxygen, fuel and ignition source are present in almost all oxygen systems, the risk of fire can be mitigated by limiting the possibility for a chemical reaction.
