How to judge if the burner accessories have ignition failure? First, start the burner three times in a row. If it does not ignite, it is judged as an ignition failure, and corresponding inspections are required to eliminate the fault. The fan runs normally during ignition and the procedure is correct.
1. If it is a gas source failure, check whether the natural gas pressure is normally maintained at 3-5kpa. Too high or too low will cause ignition failure. Solution (adjust the natural gas pressure and set the pressure).
2. If it is a damper failure, check the size of the damper. When the damper is too large, it is easy to cause multiple ignition failures. The solution is; (adjust the damper appropriately, but do not close it completely).
3. If the ignition electrode or ignition transformer fails, the ignition transformer does not ignite, or the ignition electrode is too dirty and the position is wrong, an ignition failure will occur. Solution (test whether the ignition transformer ignites, clean the ignition electrode, and adjust the ignition gap to keep 2-3mm).
4. If the gas valve group fails, the valve group will open in time during normal ignition and the sound of opening can be heard. If it cannot be opened, no flame will be established. The solution is (check the valve group coil and adjust the valve opening degree).
5. Ignition controller failure. All ignition programs are issued by the controller. If the controller is damaged, it cannot ignite normally. Solution: (Replace the controller).
So how to judge whether the burner accessories are flameout failure?
(1) When the burner accessories are burning normally, they suddenly extinguish the fire, which is a flameout failure.
(2) After the unstable gas source causes the flame to fluctuate, extinguish the fire. Solution: adjust the pressure and restart.
(3) Flame detector failure. When the flame detection probe is grounded during operation, or it is too dirty, the normal flame cannot be detected, resulting in flameout. Solution: adjust the probe position and clean the probe surface. Restart.
(4) Circuit failure. The power supply is unstable or the phase is missing, causing flameout during the process. Solution: Contact an electrician to check the power supply and wiring. Burner does not start. Press the start button for a long time and the burner does not start. External interlocking fault: The external temperature or pressure control does not reach the starting lower limit; check the temperature or pressure setting value. The internal interlocking of the burner accessories does not pass when the air pressure is too high or too low, when the wind pressure switch is normally closed and not closed, and when the damper mechanism is not in place. Check step by step. 3. The program controller fails to reset, and reset it again.
(5) The fan motor is overheated and the thermal relay is reset.
(6) Check the control cabinet start button to see if it is normal.
6. Circuit fault: Check whether the circuit starts and the voltage fuse is normal.
