Gates & Dampers
Fusion Engineering supplies gates and dampers for isolation and flow control in boiler air and flue-gas ducting, ash handling, and material handling systems. Designs can be configured for high-temperature and corrosive environments and tailored to customer requirements.
Product Range
- Flue-gas dampers: Guillotine, single-louver, multi-louver, and butterfly types for isolation and flow control.
- Isolation dampers: Tight shut-off and double-blade designs to limit gas leakage during shutdown or maintenance.
- Control dampers: Modulating parallel- or opposed-blade designs for flow and pressure regulation.
- Expansion and duct dampers: Fabric or metallic expansion dampers, sealed frames, and inlet or outlet dampers for boilers, APHs, and ID/FD/PA fans.
- Diverting dampers: Two-way and three-way diverters and bypass dampers for changing flow paths.
- Penstock, slide, and ash-handling gates: Manual or motorized slide gates, penstock gates, clinker-grinder inlet gates, hopper isolation gates, double-flap valves, and dome valves.
- Air-control gates: Primary, secondary, and tertiary air gates and dampers for combustion-air distribution.
Materials, Actuation, and Standards
- Materials include carbon steel, Corten steel, stainless steel, and alloy steel for high-temperature applications.
- Manual, pneumatic, electric, and hydraulic actuation, with gearboxes, limit switches, positioners, and solenoid valves.
- Designs can follow ASME, IS, DIN, and customer specifications and be tested for leakage, operation, and endurance.
