Principle of low nitrogen burner
What is the principle of the 30mg low nitrogen burner flue gas external circulation system?
The 30 milligram low nitrogen burner technology solution is equipped with an external flue gas recirculation system to reduce NOx emissions and meet strict emission standards. The external circulation system is a mixture of combustion air and flue gas that is burned again in the burner. This mixture is transported without an air pump in the integrated burner, and operated through external ventilation in the fission device.
For the disadvantage of a 30mg low nitrogen burner, the blower power should be increased to reduce operating efficiency. Low nitrogen solution, after years of experience and technical improvement, we are able to address this deficiency. We are equipped with a 30mg low nitrogen burner flue gas circulation system to reduce NOx emissions and meet emission standards. As mentioned earlier, the circulation system mixes combustion air and flue gas before being burned again by the burner. The mixture in the single piece burner can be transported by air to the pump, and the separator is equipped with an external fan.
There are many factors that affect nitride emission, among which the main ones are:
1. Technology adopted by the burner
2. Fuel
3. Use of thermal equipment
4. Combustion gas temperature
5. Temperature of hot medium
6. Furnace heat capacity
When the flue gas external circulation system further reduces the nitrogen concentration level, another parameter is introduced. The flue gas flow rate in the flue gas circulation generally does not exceed 20% of the flow rate provided by the air device, which should be adjusted according to the requirements of different equipment air flow rates. It is also necessary to consider that the flue gas circulation system is not working. Due to the interaction of many factors, each corresponding device in the circulation is not the same. However, in any case, due to the replacement of fresh combustion supporting gas in this part, The flue gas recirculation power of a single piece burner is relatively low. Flue gas recirculation reduces the oxygen content of fresh air, thereby reducing fuel combustion efficiency.
