Characterizing Dust Explosions

Chilworth has dust explosion test equipment.

Dust explosion test equipment is available which can measure both the sensitivity of dust clouds to different ignition sources as well as strength of explosion. Data is used in the design of plant to reduce the risk of incidents and to enable the safe control of explosion effects.

Minimum Ignition Energy Apparatus
To measure the sensitivity of a dust cloud to electrostatic spark ignition so that appropriate precautions can be taken. A spark calibrator option is also available.

Minimum Ignition Temperature Apparatus
Used to establish maximum permissible surface temperatures of process plant. Also used in the specification of electrical equipment in hazardous areas.

20-Litre Sphere Apparatus
For the measurement of maximum explosion pressure and Kst value. Data is used in the design of explosion protection devices and systems.

Explosion Demonstrator
Self-contained kit to demonstrate small dust explosions to others.

Explosion Screening Apparatus
A laboratory version of the explosion demonstrator that enables the formal classification of powders as either flammable or non-flammable.

Hartman Bomb Apparatus
A small scale alternative to the 20-Litre sphere when only small powder samples are available.

Maximum Oxygen Concentration Apparatus
For use with Explosion Screening Apparatus to establish inert gas requirements in oxygen reduced atmospheres.
