Combustion skills to reduce NOx of low-nitrogen burners:
Low nitrogen burner NOx is produced by combustion, and the combustion method and combustion conditions have a great impact on the generation of NOx. Therefore, NOx can be reduced by improving the combustion technology. The main ways are as follows:
1. Select fuel with lower N content, including fuel denitrification and conversion into low-nitrogen fuel; 2. Reduce the excess air coefficient and prevent over-rich combustion to reduce the concentration of oxygen around the fuel;
3. When there is little excess air, reduce the temperature peak to reduce "thermal reaction NO"; 4. When the oxygen concentration is low, increase the time that combustibles stay in the flame front peak and reaction zone.
The specific methods commonly used to reduce the formation and emissions of NOx are: staged combustion, reburning method, low oxygen combustion, rich and light biased combustion and flue gas recirculation.www.burners-china.com
