NOx reduction.
At Nippon Gases we are called “The Gas Professionals” for a reason, and it’s because we’ll be able to solve any doubt.
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.
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.
Uses
Stoichiometric ratio adjustment.
Two-stage combustion is promoted.
Not to create hot spot on the crown.
Possible reduction of 3-5% fuel consumption.
The solution for large productions.
Reduce NOx emissions.
Temperature profile mostly unchanged.
Minimum flame disturbance.
NOx reduction is achieved by reducing primary stoichiometric ratio.
