How to troubleshoot burner ignition and flameout faults

　　If it is ignition fault, how to judge? First, start the burner for three times in a row. If there is no ignition, it is judged to be ignition fault.The fan operates normally and the procedure is correct.31mBoiler Burner

　　1. If it is a fault of gas source, check whether the pressure of natural gas is normally maintained at 3-5kpa. If it is too high or too low, the point will not catch fire.Treatment method (adjust natural gas pressure regulation, pressure setting).31mBoiler Burner

　　2. If the valve fault should check the size of the valve, the valve is prone to multiple ignition failure when the valve is too large, treatment method;Turn the damper down properly, but do not close it completely.31mBoiler Burner

　　3. If the ignition electrode or the ignition transformer fails to fire, or the ignition electrode is too dirty in the wrong position, the ignition fault will occur.Treatment method (test ignition transformer for ignition, clean ignition electrode, adjust ignition gap to maintain 2-3mm).31mBoiler Burner

　　4. If it is the fault of gas valve set, the valve set will be opened in time and the sound of opening can be heard. If it cannot be opened, the flame will not be established.31mBoiler Burner

　　5. Ignition controller malfunction all ignition procedures are issued by the controller. The controller is damaged and cannot be fired normally.Treatment method;(replace the controller).31mBoiler Burner

　　What is stalling fault?31mBoiler Burner

　　(1) when the burner is in normal operation and burning, it suddenly extinguishes the fire, which is a flameout fault.31mBoiler Burner

　　(2) fire fighting and treatment methods after flame fluctuation caused by unstable air source;Adjust the pressure and restart.31mBoiler Burner

　　(3) when the flame detector fails to operate, the flame detection probe is grounded, or when the flame is too dirty, the normal flame cannot be detected, and the flame will turn off.Treatment method;Adjust probe position and clean probe surface.Restart.31mBoiler Burner

　　(4) circuit failure, unstable power supply or phase loss, resulting in shutdown in the process.Treatment method;Contact electrician to check power supply and wiring.Failure to start the burner press the start button for a long time and the burner will not start.Check temperature or pressure Settings.When the air pressure is too high or too low, the air pressure switch is often closed and not closed, and the damper mechanism is not in place, it will appear, step by step check.3 program controller failure to reset, reset again.31mBoiler Burner

　　(5) fan motor overheating protection, reset the thermal relay.31mBoiler Burner

　　(6) check whether the start button of the control cabinet is normal.31mBoiler Burner

　　6. Circuit fault circuit check whether the test start signal is normal, whether the voltage insurance is normal.31mBoiler Burner

　　Learn the above burner troubleshooting method, after their own can solve the fault of the burner.31mBoiler Burner
