How Does Low NOx Gas Burner Work?

Low NOx gas burners reduce NOx emissions by carefully controlling the combustion process-typically by mixing fuel and air more thoroughly, lowering the flame temperature, and sometimes recirculating flue gases. These techniques limit the formation of nitrogen oxides, which are mainly produced at high temperatures when nitrogen and oxygen in the air combine.

Key Low NOx Burner Technologies to Understand

1.Flue Gas Recirculation (FGR):Recirculates a portion of exhaust gases back into the combustion zone, lowering flame temperature and reducing NOxformation.

2.Staged Combustion:Introduces fuel and air in multiple stages, limiting oxygen and temperature peaks to minimize NOxproduction.

3. Lean Premixed Combustion: Mixes extra air with fuel before combustion, resulting in a cooler, more uniform flame and lower NOxemissions.

4. Surface-Stabilized Burners: Use carefully designed ceramic or metal surfaces to spread and stabilize the flame, allowing for lower temperature combustion and reduced NOx.

5. Catalytic Combustion:Uses a catalyst to speeds up the chemical reaction, allowing combustion to occur efficiently without a visible flame and with very low NOxproduction.

6. Air to Fuel Ratio Controller: Automatically regulates the mix of air and fuel in a combustion system to maintain efficient burning and minimize emissions like NOx.

7. Overfire Air: Adds air above the main combustion zone to complete combustion and cool hot spots.

What are Ultra Low NOx Burners and Zero NOx Burners?

Ultra-Low NOx burners are advanced industrial burners designed to reduce nitrogen oxide emissions to extremely low levels—typically below 15 ppm. Zero NOx burners, on the other hand, represent emerging technologies that eliminate NOx emissions entirely by avoiding flame-based combustion, using methods like electric heating, hydrogen fuel, or plasma-assisted systems, making them ideal for zero-emission manufacturing and net-zero industry initiatives.
