BTN350/450/550/650GEFGR Flue Gas External Recirculation Technical Performance and Structural Features 1 Ultra-low nitrogen gas burner
2 Digital combustion management system, electronic proportional operation.
3. Flue gas external recirculation system. Part of the flue gas is mixed with combustion air and sent to the combustion chamber to support combustion. The mixed combustion air can reduce the temperature and oxygen concentration in the combustion chamber, effectively inhibiting the generation of NOx.
4. Multiple nozzles, decentralized combustion, preventing excessive flame concentration that leads to high oxidation reactions.
5. Utilizes three servo motors to precisely control the ratio of combustion air volume, gas volume, and flue gas volume.
6. Connected and fixed to the boiler using one flange and a high-temperature insulation gasket.
7. Three-phase motor drives the fan.
8. UV flame detector monitors the flame.
9. Standard electrical protection rating IP40.
