Technical Principle
Recirculating the purified flue gas back into the incinerator reduces the oxygen concentration within the incinerator and inhibits NOx formation, resulting in low NOx emissions. The recirculated flue gas can partially replace the role of secondary air, while maintaining mixing and turbulence effects.
Technical Advantages

• Broad Applicability: Suitable for NOx emission reduction in waste incineration.

• Minimization: Significantly reduces the generation of thermal NOx.

• Operability: Ensures stable operation during continuous service.

• Cost-Effectiveness: Improves thermal efficiency and reduces reducing agent consumption.


Application Project Case

Scale: 3*750t/d

Denitrification technology: 1# running SNCR+SCR, 3# running SNCR+EGR

Operation effects: Reduce NOx emission indicators, save operating costs, and increase steam production per ton of waste
