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.
