How to reduce the combustion technology of low nitrogen burner NOx?
NOx is generated by combustion, and the combustion method and combustion conditions have a great influence on the generation of NOx, so NOx can be reduced by improving combustion technology, the main ways are as follows:
in low nitrogen burner NOx
1. Use fuels with low N content, including fuel denitrification and conversion to low nitrogen fuel;
2. Reduce the air excess coefficient and organize over-rich combustion to reduce the concentration of oxygen around the fuel; 3. In the case of less excess air, reduce the temperature peak to reduce "thermal reaction NO";
4. In the case of low oxygen concentration, increase the time that combustibles stay in the flame front and reaction zone.
The specific methods commonly used to reduce the formation and emission of NOx are: staged combustion, reburning method, low-oxygen combustion, rich-lean deviation combustion and flue gas recirculation
