Industrial Applications

Double Flap Dampers in power plants serve as critical isolation and material discharge devices, ensuring gas-tight sealing in ash handling and flue gas duct systems.

Application 1

ESP Hopper Ash Discharge

Controls timed gravity discharge of collected fly ash from ESP hoppers into pneumatic conveying lines while maintaining ESP negative pressure.

Application 2

Bottom Ash Hopper Isolation

Provides gas-tight shutoff at boiler bottom ash hopper outlets during clinker removal, preventing hot air ingress into the ash handling system.

Application 3

Flue Gas Duct Emergency Isolation

Isolates boiler flue gas ducts during emergency trips or maintenance, preventing backflow through induced-draft fan systems.
