Chapter 1: Techniques for LoNox Burners

This chapter delves into the various techniques employed by LoNox burners to achieve significant reductions in NOx emissions. These techniques are based on manipulating the combustion process to minimize the formation of NOx molecules.

1.1 Low-Excess Air Combustion:

• This technique focuses on optimizing the air-fuel ratio within the burner. By reducing the amount of excess oxygen available during combustion, the formation of NOx is significantly hindered.
• This method relies on precise control of the air and fuel flow rates, ensuring a leaner combustion environment with minimal excess oxygen.

1.2 Multi-Stage Combustion:

• This approach involves breaking down the combustion process into multiple stages, each with specific temperature and oxygen levels.
• By carefully controlling these parameters in each stage, the peak temperature and oxygen concentration are kept low, minimizing NOx formation.
• The stages can include premixing, primary combustion, and secondary combustion zones.

1.3 Flue Gas Recirculation (FGR):

• This technique involves recycling a portion of the flue gas back into the combustion chamber.
• The recirculated flue gas, rich in inert gases like CO2 and N2, dilutes the combustion mixture, lowering the peak temperature and inhibiting NOx formation.
• FGR can be implemented using different configurations, such as internal and external recirculation systems.

1.4 Selective Catalytic Reduction (SCR):

• This technique involves passing the flue gas through a catalyst bed, where NOx molecules are chemically converted into nitrogen and water.
• The catalyst is typically a metal oxide, like vanadium oxide, that promotes the reduction reaction with a reducing agent, such as ammonia or urea.
• SCR is a post-combustion technology, requiring a separate reactor downstream of the burner.

1.5 Other Techniques:

• In addition to the primary techniques, other strategies can further optimize NOx reduction, including burner design optimization, fuel preheating, and staged air injection.

1.6 Conclusion:

• LoNox burners utilize a combination of these techniques to achieve significant NOx reductions, tailored to the specific application and environmental regulations.
• Understanding these techniques is crucial for selecting the appropriate LoNox burner for a given process, ensuring both environmental compliance and operational efficiency.
