What is the principle of the flue gas external circulation system of a 30mg low nitrogen burner?
30 mg low nitrogen burner technology solutions, outside is equipped with flue gas recycling system to reduce nox emissions, to meet the stringent emission standards, outside circulation system is a mix of combustion-supporting air and flue gas to the burner to burn again, this mixture in one-piece burner is free with the wind to pump for conveying, and in the fission device is operated by external ventilation
As for the disadvantages of the 30mg low nitrogen burner, the power of the blower should be increased and the operating efficiency should be reduced.Low nitrogen solution, after our many years of experience and technology improvement, we are able to solve the shortcomings in this respect, equipped with flue gas circulation system of 30 mg low nitrogen burner, reduce nox emissions and to meet the emission standards, as said before, the circulatory system is after mixing combustion air and flue gas to the burner to burn again, the mixture in one-piece burner is free with the wind to pump for conveying, and in the separator is external wind machine to do this.
There are many factors affecting nitride emission, among which the main ones are:
1. Technology adopted by burner
2. The fuel
3. Use thermal equipment
4. Combustion-supporting gas temperature
5. Heat medium temperature
6. Furnace heat capacity
When the gas outside circulation system further reduce nitrogen concentration level, introduces another parameter, flue gas flow in the cycle of flue gas recirculation quantity is generally not exceed 20% of the wind device provided by the flow, should be adjusted according to the requirements of different equipment air volume, also need to consider the flue gas circulation system does not work, due to the interaction of many factors, each device corresponding in circulation is not the same, but anyway, because of the part was replaced by fresh combustion-supporting gas, flue gas recirculation of one-piece burner less power.Flue gas recirculation reduces the oxygen content of the fresh air and therefore the fuel combustion efficiency.
