Introduction to the troubleshooting methods of the burner

To 　　: 　　 Ignition failure Under normal conditions, the burner has been started three times in a row. If it fails to ignite and burns, it should be judged as an ignition failure, and corresponding inspections are required to eliminate the failure. The burner is malfunctioning (the fan runs normally during ignition and the program is correct) 　　 ● Ignition failure 　　 Under normal conditions, if the burner is started three times in a row, if it is not ignited and burned, it should be judged as an ignition failure, and corresponding inspections are required to eliminate the failure. (The fan runs normally during ignition and the program is correct) 　　 1 Gas source failure Check whether the pressure of natural gas is normally maintained at 3-5kpa. If it is too high or too low, it will not catch fire. Treatment method: adjust the natural gas pressure regulator and set the pressure. 　　 2 Damper failure Check the size of the damper. When the damper is too large, it is prone to fail to ignite several times. Solution; adjust the damper appropriately, but it cannot be completely closed. 　　 3 Ignition electrode or ignition transformer failure If the ignition transformer does not ignite, or the ignition electrode is too dirty in the wrong position, an ignition failure will occur. Treatment method; test whether the ignition transformer is ignited, and the troubleshooting method is introduced to clean the ignition electrode and adjust the ignition gap to maintain 2-3mm. 　　 4 Gas valve group failure. During normal ignition, the valve group will be opened in time, and the opening sound can be heard, and no flame will be established when it cannot be opened. Treatment method; check the valve group coil and adjust the opening of the valve. 　　 5 Ignition controller failure All ignition programs are issued by the controller, and the controller is damaged and cannot be ignited normally. Treatment method; replace the controller. 　　 ●Flameout failure When the burner is running and burning, it suddenly extinguishes fire, which is a flameout failure. 　　 1 After the unstable gas source causes flame fluctuations, extinguish the fire, and how to deal with it; adjust the pressure and restart. 　　 2 Flame detector failure The flame detection probe is grounded during operation, or when it is too dirty, no normal flame can be detected, and flameout occurs. Processing method; adjust the probe position and clean the probe surface. Restart. Caused flameout during the process. Treatment method; contact an electrician to check the power supply and wiring. 　　 ●The burner does not start fault. Press the start button for a long time and the burner does not start 　　 1 External interlocking failure The external temperature or pressure control does not reach the lower start limit; check the temperature or pressure setting value. 　　 2 The internal interlock of the burner failed. When the air pressure is too high or too low, the air pressure switch is normally closed and is not closed, and the air door mechanism is not in place, both will appear. Check step by step. 　　 3 The program controller has not been reset for faults, so reset it again. 　　 4. Fan motor overheat protection, reset the thermal relay. 　　 5. Check whether the start button of the control cabinet is normal. 　　 6. Circuit failure Check whether the start signal is normal and the voltage insurance is normal.
