Bucket Conveyor Dust Explosions Controlling Ignition

Jan 03, 2018 A dust explosion occurs in a bucket conveyor when combustible dust accumulates in sufficient concentration within the enclosed space of the conveyor and is exposed to an ignition source. Since the ignition source is the trigger which sets off the explosion, controlling the possible sources of ignition through good equipment design can reduce ...

Guidelines for bucket elevators MyNSightOnline

Guidelines for bucket elevators MyNSightOnline

Grain dust explosions and fires are serious safety hazards in grain-handling facilities. Grain dust explosions can be more powerful than dynamite. Under the right conditions, even a small ignition source can trigger a devastating explosion that can destroy an entire facility. Most dust explosions initially occur in the bucket elevator.

Combustible Dust Explosions in Bucket Elevators

Combustible Dust Explosions in Bucket Elevators

Jul 10, 2017 Explosion suppression equipment detects a dust explosion in the first milliseconds of the event and then signals extinguishing modules to release a flame quenching medium into the bucket elevator. This stops the explosion in its infancy and only low pressure is produced that is safe for the bucket elevator and connected equipment.

Any bucket elevator leg conveying grain is susceptible to grain dust explosions. The more grain conveyed with a particular leg, the greater the likelihood of a grain dust explosion. The possibility of a grain dust explosion exists in small on-farm legs, but it is much greater in larger commercial legs conveying millions of bushels of grain each year.
