O.E.N.R. (Oxygen Enhanced NOx Reduction)

Oxygen Enhanced NOx Reduction.

More stringent NOx regulations in EU with new BAT (Best Available Techniques) AEL (Associated Emission Level) for NOx

Cost-effective NOx mitigation technology for air-fired furnaces by using small volumes of a secondary oxidant.

30%

NOx reduction.

CO

No CO in the exhaust port.

Increased temperature

No flue gas temperature increase.

Mitigating NOx emissions by using oxygen

A low cost, low maintenance option that can be installed on allair-fired end-port regenerative glass furnaces.

O.E.N.R. technology uses CFD (Computational Fluid Dynamics) modeling to optimise burner/lancing design and position to reduce NOx emissions. A two-stage combustion is promoted to get adequate levels of NOx. Compelling technical alternative to conventional air staging or oxygen-enriched air staging for NOx reduction.
