What are the operating methods for low nitrogen burners
Low nitrogen burner is the general name of the devices that make fuel and air spray burn in a certain way. It is often made of corrosion-resistant and high-temperature materials such as stainless steel or titanium metal. The function of a low nitrogen burner is to atomize the sample through flame combustion. The atomized test solution enters the low nitrogen burner. Under the influence of flame temperature and flame atmosphere, a large number of ground state atoms, as well as some excited atoms, ions, and molecules, are generated through processes such as drying, melting, evaporation, and dissociation. 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. Let's learn how to use a low nitrogen burner.
1. Press the main ignition button on the combustion control panel. After the main fire indicator light is on for 10 seconds, confirm that the main fire has been ignited. If the main fire indicator light goes out within 10 seconds, the combustion fault alarm buzzer on the combustion control panel will sound, indicating ignition failure; After 60 seconds, manually press the fault reset button on 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 observation hole of the low nitrogen burner. After confirmation, press the high fire start button on the low nitrogen burner control panel. After a few seconds of delay, when the high fire indicator light is on, the operator in front of the furnace should slowly open the load regulating ball valve and increase the gas auxiliary air proportionally until the flame shows a main blue or slightly red color.
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 if the low nitrogen burner is in normal condition.
5. Observe the gas and air pressure indicators to confirm if a low nitrogen burner operation permit instruction is provided.
6. Press the combustion control button on the combustion control panel, and the combustion control equipment will enter the combustion start program.
7. The task of the next firing has been completed. The operator should promptly turn off the main fire button on the panel of the low nitrogen burner, cut off the main fire, and keep the fire burning.
8. Operators can adjust the flame size at any time during the combustion process according to process requirements. When the process requires a short shutdown time, the operator should first turn on the main fire switch to retain the main fire, and then turn off the high fire switch.
9. Adjust the operating handles of the gas valve and air valve, which can be adjusted in stages to ensure that the load output of the low nitrogen burner meets the process requirements.
10. Shutdown operation: Temporary shutdown, first turn off the fire, then turn off the combustion control switch, and then turn off the stop button.Author：Ebico
