Troubleshooting method for burner flameout:
1, gas source instability caused by the fire du flame fluctuation, fire extinguishing.Method of zhi management;Adjust pressure,restart;
2. When the flame detector fails to operate, the flame detection probe grounding, or when it is too dirty, the normal flame cannot be detected and flameout occurs.Treatment method;Adjust probe position, clean probe surface and restart;
3, circuit fault power instability or phase lack, resulting in the process of flameout.Treatment method;Contact electricians to check power supply and wiring.
Technical operation
1. Press the master fire start button on the combustion control panel.Confirm that the mother fire is lit after the working indicator has been on for 10 seconds.If the mother fire indicator goes out within 10 seconds, the fire failure alarm buzzer on the combustion control panel will sound, indicating that the ignition has failed.After waiting for 60 seconds, press the program controller fault reset button manually and restart the master fire button.
2. After the mother fire is lit normally, the operator shall confirm whether the mother fire is lit through the observation hole of the burner.After confirmation, press the fire start button on the burner control panel. After a few seconds of delay, after the fire work indicator lights up, the operator in front of the furnace should slowly open the load adjusting ball valve and increase the gas air proportionally until the flame appears the main blue and slightly red color is the best.
3. After the fire is ignited and stabilized, check whether the gas supply pressure of the main pipeline is in the normal range;
4. Start the fan, enter the pre-blowing stage, check and confirm that the equipment is in normal state;
5. Observe the gas and air pressure indication, and confirm that the burner operation permission instruction is given;
6. Press the combustion control button on the combustion control panel, and then the combustion controller enters the combustion start program;
7. The ignition task of minghuo has been completed.Operators should timely close the mother-fire button on the panel, cut off the mother-fire to keep the fire burning;
8. Operators can adjust the size of flame (load) at any time according to the process requirements in the process of big fire burning.When it is required to turn off the fire for a short time, the operator should turn on the master fire switch to keep the master fire, and then turn off the fire switch.
9. Adjust the operating handle of gas valve and air valve, which can be adjusted in stages to ensure that the burner's load output meets the technological requirements;
10. Stop operation: when the machine is temporarily shut down, the fire should be shut down first, then the fire control switch should be closed, and the stop button should be closed at last.
