The production process of blast furnace gas burners should be heated with heat transfer oil, but existing furnace gas has a large amount of tar, and the import burner cannot operate at all. Many manufacturers have also solved this problem in China. Then the exclusion method of burner failure
Introduction to the troubleshooting of burner
Exclusion of the fault of low nitrogen burner: Under normal conditions of ignition failure, the three burners are continuously launched, and there is no ignition combustion should be judged as ignition failure, and the corresponding inspection is required to troubleshoot. (The fan is operating properly, the program is correct) (The fan is operating properly, the program is correct) 1. If the gas source failure checks if the pressure of natural gas is maintained in 3-5 kPa, too high or too low will appear. Treatment method; adjust the natural gas pressure reducing valve to perform pressure settings. 2, the damper fault check the damper size, the damper is easily unexpected when it is too large, and the method is handled; the damper is properly tone, but it cannot be completely closed. 3, ignition electrode or ignition transformer fault ignition transformer does not fire, or when the ignition electrode is too dirty, ignition failure will occur. Treatment method; test the ignition transformer ignition, clean the ignition electrode, adjust the ignition gap to keep 2-3mm. 4, the gas valve group fault is normal to normally ignite, the valve group will open in time, and can hear the open sound, no flame, processing method, method; check the valve group coil, adjust the opening degree of the regulating valve. 5, ignition controller failure All ignition programs are issued by the controller, the controller is damaged, and it cannot be ignited. Treatment method; replace the controller. ● When the flameout failure is low nitrogen burner, when the burning is burned, suddenly fire extinguish, and the flameout failure. 1. After the gas source does not stabilize the flame fluctuation, fire extinguishing, treatment method; adjust the pressure, restart. 2, the flame detector faulty time the flame detects the probe grounding, or too dirty, no normal flame is measured, and the flameout appears. Treatment method; adjust the position of the probe, clean the surface of the probe. Restart. 3, circuit fault power supply instability or phase loss, thereby turning off during the process. Treatment method; contact the electrical industry to check the power and wiring.
