Coal-Conveyors
Dry Fog at Head Chute of Coal Tripper Conveyor Feed Point

Conveyor Transfer Points at port facilities can be a source of fugitive dust that can lead to contamination of waterways and  storm-water systems. Some material contains heavy metals that can not enter the water. Dust from materials such as coal and pet coke can increase the risk of fires and explosions. If coal or pet coke is being directed to a storage building, the facility must comply with OSHA and Fire and Safety Regulations. Dry Fog™ can help you comply with these regulations.

If the facility is using Dust Collection for coal or pet coke, Dry Fog can replace these collectors, increasing safety and lowering operating cost. Dry Fog eliminates dust explosion risk associated with dust collection systems. The explosive waste stream is eliminated as we do not collect the dust, but simply "knock down" the airborne dust at the point of creation. Therefore, we do not create a secondary waste stream that creates a high concentration of explosive dust that is typically put back onto the conveyor belt only to create more issues downstream.

Dry Fog works by injecting sub-micron water droplets into the air at the point of dust creation. The fog droplets attach to like size airborne dust particles. The slightly wetted particles agglomerate to other particles, adding sufficient mass to settle the dust back into the conveyed product within the covered transfer point. Use at ship holds, grab hoppers, screens, coal yard & plant conveyors, including reclaim, gallery, tripper conveyors and silos.
