The Double Blade Circular Flue Gas Damper is a heavy-duty circular duct control device specially designed for flue gas,exhaust gas,and high-temperature ventilation systems.Featuring a robust dual-blade synchronous structure and full-circle sealing design,this damper is engineered for precise flue gas regulation,tight shutoff,and effective pipeline isolation.It can be manually operated or fitted with electric,pneumatic,or explosion-proof actuators to meet automatic control requirements in industrial flue systems.
Widely used in power plants,boilers,chemical exhaust systems,industrial furnaces,and flue gas treatment projects,it effectively adjusts flue gas flow,balances pipeline pressure,and blocks gas backflow,ensuring stable and safe operation of industrial exhaust and environmental protection systems.
Core Features
1.Professional Double-blade Flue Gas Structure
Adopts optimized double-blade linkage design with uniform force distribution and strong overall rigidity.Compared with single-blade dampers,it provides better rigidity,stronger wind pressure resistance,and more stable opening/closing synchronization,effectively avoiding deformation and shaking under high-temperature flue gas impact.
2.Excellent Sealing&Low Leakage Performance
Equipped with high-temperature resistant sealing gaskets and precision blade fitting structure.The double-blade overlapping sealing design greatly reduces gas leakage,achieving reliable shutoff effect.It effectively prevents flue gas backflow,dust leakage,and pipeline pressure loss,fully meeting industrial flue gas isolation standards.
3.High Temperature&Corrosion Resistance
The circular frame and blades are made of high-quality galvanized steel,carbon steel or stainless steel materials,with optional high-temperature resistant coatings.The whole structure is anti-rust,anti-oxidation and corrosion-resistant,adapting to long-term operation in high-temperature,dusty and corrosive flue gas environments.
4.Stable Flow Regulation&Pressure Balancing
The double-blade synchronous adjustment provides linear and accurate airflow control.It can flexibly adjust flue gas volume and balance system pressure,avoiding unstable air volume and system vibration caused by excessive or insufficient exhaust gas discharge.
5.Flexible Driving&Easy Installation
Supports manual,electric,pneumatic and explosion-proof actuation for different automatic control needs.Standard circular flange structure matches all conventional round ducts,enabling quick installation,convenient maintenance and no complex pipeline modification.
Main Applications
-Power plant boiler flue gas exhaust systems
-Industrial furnace and kiln ventilation&exhaust control
-Chemical,pharmaceutical and factory waste gas treatment pipelines
-Environmental protection dust removal and flue gas purification systems
-High-temperature ventilation and industrial air balance systems
Product Advantages
The Double Blade Circular Flue Gas Damper is specially optimized for harsh industrial flue gas working conditions.Its double-blade reinforced structure ensures high stability and low deformation,while the upgraded sealing system realizes ultra-low gas leakage.With high temperature resistance,precise flow adjustment and diverse control methods,it is the ideal choice for industrial flue gas cut-off,regulation and pipeline isolation.
