How to Operate the Low Nitrogen Burner?
A well-designed low nitrogen burner should have high atomization efficiency, low noise, and stable flame performance to ensure high absorption sensitivity and measurement accuracy. Now let’s see how to operate the low nitrogen burner.
1. Press the main ignition button on the combustion control panel. After the main fire indicator is on for 10 seconds, confirm that the main fire has been lit. If the main fire indicator goes out within 10 seconds, the combustion failure alarm buzzer on the combustion control panel will sound, indicating that the ignition has failed; After 60 seconds, manually press the fault reset button of the programmer to restart the main ignition button.
2. After the main fire is ignited normally, the operator confirms whether the main fire is ignited through the low nitrogen burner observation hole. After confirmation, press the high fire start button on the low nitrogen burner control panel. After a few seconds of delay, after the high fire indicator light is on, the operator in front of the boiler should slowly open the load regulating ball valve and increase the gas auxiliary air proportionally until the flame is blue or slightly red.
3. After the fire is ignited and stabilized, check whether the gas supply pressure of the main pipeline is within the normal range.
4. The fan starts and enters the pre-blowing stage. Check whether the low nitrogen burner is normal.
5. Observe the gas and gas pressure indicators to confirm whether there is a low nitrogen burner operation license manual.
6. Press the combustion control button on the combustion control panel, and the combustion control equipment will enter the combustion start procedure.
7. The mission of the next launch has been completed. The operator shall timely turn off the main fire button on the low nitrogen burner panel, cut off the main fire, and keep the fire burning.
8. The operator can adjust the flame size at any time according to the process requirements during the combustion process. When the process needs to shut down the fire for a short time, the operator should first turn on the main fire switch to maintain the main fire, and then turn off the high fire switch.
9. The adjustment of air valve and air valve operating handle can be adjusted in stages to ensure that the load output of the low nitrogen burner meets the process requirements.
10. Shutdown operation: shut down the machine temporarily, first turn off the fire, then turn off the combustion control switch, and then turn off the stop button.
