Type and installation requirements of low nitrogen burners
Low nitrogen burner mouth is an important equipment on industrial fuel boilers and gas boilers. It guarantees fuel to stabilize the complete combustion of fire combustion and fuel. Here is simple to tell you about the current low oxide of our low nitrogen burner manufacturers. Type of burnt mouth: 1 The working principle of the low nitrogen burner of the exhaust gas self-circulating low NOx burner is mainly used to use air injection to return a part of the combustion products to the vicinity of gas air into the vicinity of gas air, thereby reducing The oxygen concentration in the circulatory area prevents the formation of local high temperature zones. According to the relevant information, when the exhaust gas recirculation rate is about 20%, the effect of suppressing the NOx is high, and the emission concentration of NOx is below 80 g / m3. Low nitrogen burner burner 2 Two-stage combustion low NOx burner This kind of low nitrogen burner of the burner is to enter the combustion zone twice in combustion, thereby dividing the combustion process. The stage is completed, avoiding the high temperature zone too concentrated. Since the amount of air is only 40% to 50% of the total air volume, a strong reducing atmosphere is generated, and the low oxygen concentration region is formed, and the temperature of the combustion reaction zone is reduced, inhibiting the formation of NOx, the rest of the air ( Secondary air) is from the periphery of the restore combustion zone, and it is fully burned at the tail of the flame. Due to the implementation of segmental combustion, avoid high temperature zone concentration, so NOx's emission concentration is significantly reduced. Low nitrogen burner low nitrogen burner After understanding the type of low nitrogen flask, let's take a look at the installation requirements of the burner: 1. When the burner is installed, it must be required to install the burn-up centerline and the burner brick center line. 2. The burner housing and the burner brick are installed. 3. The barrel of the burner should be fixed on the bracket on the furnace steel column. 4. The sequence of installation is to first load the burnout, the rear gas pipe, and should not affect the burnout positioning when installing the oil pipe. 5. The hot air imports of the burner should be mounted above or both sides to avoid being installed below. 6. When the burner is installed with refractory material, it must be filled between the baffle and the housing. Prevent the baffle from sinking and pressing the oil gun.
