VBR Series – Vibrating Dry Bottom Ash Conveyor

VBR Series vibrating conveyors represent the latest dry bottom ash handling technology, eliminating the need for water or ponds. The system uses a vibrating deck under the boiler to gently move ash to a crusher, then to a secondary conveyor. No moving mechanical parts exist under the boiler, reducing wear and maintenance while improving heat recovery. A fluidized vibrating bed allows combustion of unburned ash and forces cooling air upward, boosting boiler efficiency and extending system life. Ideal for modern power plants seeking a 100% dry, energy-efficient solution with minimal environmental impact.
