1、 Burner structure
From the outside to the inside, they are: axial flow air, swirl air, main gas, and center air.
2、 The role of each channel:
1. Axial flow air: It plays a role in wrapping the flame, controlling its divergence, disorder, and absorbing high-temperature secondary air. In addition, the bowl shaped effect formed by the outer flame hood makes the flame more reasonable. Its wind speed: 160-220m/s (belonging to axial wind).
2. Swirl air: Strengthen air air mixing, improve gas combustion speed and burnout rate. Its wind speed: 120-180m/s (belonging to radial wind)
3. Main gas: The gas channel during the production process.
4. Central air: Supply oxygen to the central part of the flame for combustion and stabilize the flame. Its wind speed: 40-60 m/s.
3、 Steps for ignition and heating up:
1. Power on the valve group and open the pilot gas valve at the same time to check the opening and closing of the electric valve,.
2. For the first ignition, prepare a torch with a front end covered with diesel about 6 meters. After igniting the torch, place it directly below the burner nozzle, so that the flame of the torch directly contacts the front nozzle of the burner. It is necessary to adhere to the safe ignition principle of "fire and gas".
3. After the flame stabilizes, slowly turn on the gas and ignite the main gas with the torch source.
4. Once the main gas combustion is stable, primary clean air (i.e. combustion air) can be introduced. Adjust the axial flow air, swirl air, and center air electric butterfly valves appropriately to control the normal and stable combustion of the flame.
5. According to the heating needs in the kiln, adjust the gas volume and various electric butterfly valves appropriately to control the flame.
6. During normal operation, ignite the ignition and turn on the fan to blow for 10 minutes before starting the ignition button.
matters needing attention:
Before ignition, the fan should be turned on and purged for at least 15 minutes.
If the ignition fails within 20 seconds, immediately cut off the gas circuit, stop ventilation, and clean the residual gas in the kiln. Only after checking and troubleshooting can the ignition be restarted.
After the combustion stabilizes, wait for the torch to remain for 10 minutes before withdrawing.
During the ignition and heating up period, the primary clean air should be adjusted appropriately based on the amount of gas used, and should not be used too much to prevent blowing out the flame.
Any shutdown should first clean the residual gas in the kiln, then check and eliminate the fault before re igniting. For more technical details, please call (WeChat synchronization): 15713691937.
