Reasons For Popularization Of Industrial Low NOx burners (Why Promote Low Nitrogen Burners)
Low NOx burner refers to the burner with low NOx emission during fuel combustion. Selecting a low NOx burner can reduce NOx emissions during combustion.

The stand-alone fully automatic low nitrogen burner is like a flame injector, which injects the flame products of fuel oil into the combustion chamber in the furnace to achieve complete combustion and output heat in the furnace. The practical products of the low nitrogen burner are completely burned. The measurement is carried out in a specific standard combustion chamber, so the conditions of the standard laboratory are usually used as the selection conditions for matching the low nitrogen burner with the boiler.

The low nitrogen burner can be summarized as follows:
(1) Power supply;
(2) Air pressure in the furnace;
(3) The size of the space and the length of the furnace diameter.

The matching of aerodynamic characteristics means the satisfaction of these three conditions. The power of the low nitrogen burner refers to the number of kilograms and volumes of fuel that can be burned per hour and the corresponding heat output at the same time when fully burning. In China, the standard specifications of boilers are steam output value and fuel consumption. Therefore, when selecting, the two must match.

In the standardized boiler, the hot gas flow starts from the low nitrogen burner and enters the atmosphere through the furnace, heat exchanger, flue gas collector, and exhaust channel, forming a process of overall thermal activity. The hot gas flow generated after the combustion of low nitrogen burner fuel, the pressure generated by entering the inlet moves in the combustion chamber in the furnace and moves to the outlet like river water. As the furnace wall, channel, elbow, baffle and emptying channel of the furnace combustion chamber have a certain resistance to the smooth movement of gas, this will lead to pressure loss. Therefore, a certain flue gas pressure must be maintained in the furnace. For the use of a burner, the furnace pressure specification requires that the heat and hot air pressure reach the exhaust pipe. The pressure shall be higher than atmospheric pressure so that the residual exhaust gas can be discharged into the atmosphere smoothly.
