Ash-to-Truck-bed-length-side-viewStrip Curtains help direct Dry Fog into the truck bed, creating a "Fog Reservoir"

Controlling dust from Ash Handling can be challenging. Adding enough moisture to the ash to prevent dust is difficult, if not impossible. Mixing the ash with water often creates maintenance issues, including broken paddles and mixing screws. The Hydrophobic nature of ash typically results in some percentage of ash being over-wetted and the balance not wetted at all. Over-wetted ash drys out when spilled onto the ground, creates a secondary source of dust and must be cleaned up. If used for structural landfill, over-wetting can take ash out of specification. Dry Fog Systems use very little water and enables your operation to meet Environmental Compliance while meeting ash compaction specs. It will reduce the mess and increase truck haul capacities. One plant has reduced haul trips by 19%. Big savings!

Dry Fog systems can operate in temperatures well below freezing. At the same time, fog will not freeze in most environments. As the photos show, the fog is injected into the truck bed at the discharge point. The truck bed acts as a reservoir for the fog to attach to the airborne dust particles as they try to escape from the truck bed area. The airborne dust particles become more cohesive and attach to other slightly wetted particles until the increased mass of the larger agglomerated dust particles make them fall back into the truck bed.

DSI can provide Strip Curtains and DustTAMER Wind Screen materials and mounting hardware to help reduce the effects of ambient wind and displaced air from the ash being discharged into the truck.
