Nitrogen oxide is one of the main sources of pollution causing air pollution. It is extremely destructive to human body, animals and plants, and the environment. Excessive emission of nitrogen oxides will directly threaten our lives.
Nitrogen and oxygen are not actively mixed together, but when the temperature reaches 1600 ° C, nitrogen and oxygen in the air are mixed to form nitrogen oxides.
At present, the low-nitrogen combustion technology of the gas boiler with better effect has full premixing and FGR.
First, full premixed combustion technology.
Before the fuel is sent to the furnace for combustion, it is thoroughly mixed with the air beforehand, and the optimal ratio is achieved through precise adjustment and control. After adding surface combustion technology, the combustion temperature in the furnace is further reduced to reduce the role of nitrogen oxides.
Second, FGR combustion technology.
FGR combustion technology is the flue gas recycling technology. The flue gas generated after the boiler is operated enters the furnace through the connecting pipe to participate in the combustion, and reduces the combustion temperature of the fuel in the furnace to reduce the role of nitrogen oxides.
If you are in the low-nitrogen reform of the headache boiler or want to buy a low-nitrogen boiler at this time, you can contact the FANGKUAI Boiler through the free service hotline above, we will be happy to help you.
