Principle of low nitrogen burner
The precombustion chamber of low nitrogen burner is a high-efficiency, low nitrogen staged combustion technology developed and researched in China in the past 10 years. The precombustion chamber is generally composed of primary air (or secondary air) and fuel injection system. The fuel and primary air are rapidly mixed to form a fuel rich mixture in the primary combustion area of the precombustion chamber. Due to lack of oxygen, only part of the fuel is burned, and the fuel releases volatiles in the oxygen poor and low flame temperature primary flame area, Thereby reducing NOx generation. Any low nitrogen combustion technology is essentially a technology that controls the combustion process. According to the 20-year experience in the use of low nitrogen burners in Europe and the United States, it is not enough to replace or transform the burners for industrial boilers to achieve truly sustainable and reliable low nitrogen combustion. It is also necessary to upgrade the combustion control device, such as adding a "timely control" combustion control device. The mixing promoting burner is designed according to this principle.
Common faults and troubleshooting of burner
In the equipment with the sealing inspection device, the picture of the imported low nitrogen burner shows that the burner motor is running and the ignition is normal, but it stops later (no fault is displayed)
(1) Unsealed solenoid valve (1) eliminate unsealed condition
(2) Insufficient air supply (2) increase air supply flow
(3) Filter blockage (3) cleaning or replacement
. the burner motor runs, the flame formation is normal, and the price of imported low nitrogen burner is low, but then it stops due to failure
(1) The ionization current is unstable and too low (1) change the position of the ionization current * and the flame plate, import the low nitrogen burner, and check the connecting line
(2) Uneven regulation of gas air mixture (2) readjust gas air mixture
(3) Ignition spark affects ionization current (3) change phase line and neutral line of primary coil of ignition transformer
