Principle Of Low Nitrogen Burner
Principle Of Low Nitrogen Burner
What is the principle of a flue gas external circulation system of 30mg low nitrogen burner?
For the technical solution of 30mg low nitrogen burner, a flue gas recirculation system is equipped externally to reduce NOx emissions and meet strict emission standards. The external circulation system is a mixture of combustion-supporting air and flue gas that burns again in the burner. This mixture is transported without an air pump in the integrated burner and is operated through external ventilation in the fission device.
For the disadvantage of 30mg low nitrogen burner, the blower power should be increased to reduce the operating efficiency. Low nitrogen solution. After years of experience and technical improvement, we can solve this problem. A flue gas circulating system with 30mg low nitrogen burner is equipped to reduce NOx emission and meet the emission standard. As mentioned earlier, the circulating system is burned again in the burner after the combustion air and flue gas are mixed. The mixture in the single-piece burner can be transported by air to the pump, and the separator is an external fan.
There are many factors affecting nitride emission, including:
1. Technology adopted by the burner
2. Fuel
3. Use of thermal equipment
4. Combustion supporting gas temperature
5. Temperature of hot medium
6. Furnace heat capacity
When the external flue gas circulation system further reduces the nitrogen concentration level, another parameter is introduced. The flue gas flow in the flue gas circulation generally does not exceed 20% of the flow provided by the wind device. It should be adjusted according to the requirements of the airflow of different equipment. It also needs to consider that the flue gas circulation system does not work. Due to the interaction of many factors, each corresponding device in the circulation is different, but in any case, because this part is replaced by fresh combustion supporting gas, The flue gas recirculation power of the single-piece burner is small. Flue gas recirculation reduces the oxygen content of fresh air, thereby reducing fuel combustion efficiency.
