The following are the methods for troubleshooting industrial burners:
The burner can be lit, but it is unstable:
It may be that the contact between the high voltage wire and the high voltage cap is not good. Please wipe it clean with cotton cloth and then connect it to try to ignite.
Replace the ignition controller and try the normal controller next to it to confirm whether the controller has a fault.
Take out the electrode and see if there is any carbon accumulation. Please clean it up or replace the electrode to try.
Whether the grounding wire in the ignition transformer is in good contact with the controller, the controller must have a good grounding. If the resistance of the brown wire in the transformer to the ground is very small, please replace the transformer.
If the air-fuel ratio is not appropriate, please adjust the air-fuel ratio parameter. Test tool electronic pressure gauge.
Check whether the feedback line behind the controller is loose and aging.
If the controller signal is unstable or no signal, replace the controller.
The burner does not ignite:
The electrode does not spark, check whether the controller has output and whether the line is in good contact.
Gas pipeline rupture or aging, regular inspection of gas pipeline and accessories to ensure normal gas supply.
The burner igniter is faulty or damaged. The igniter is damaged. Check the igniter to ensure that the igniter is in good condition.
If the valve is stuck or damaged, check the burner control valve to ensure that the control valve works properly.
The burner can be ignited and maintained normally, but the combustion condition is poor:
The combustion system is empty, and the gas-to-air ratio is inappropriate, which can be caused by improper adjustment of the air valve and gas valve openings or valve body leakage. Measure the exhaust gas concentration at the flue outlet to confirm whether the oxygen content in the exhaust gas is too high; use a portable pressure gauge to measure the air and gas pressures at the burner and adjust them to an appropriate ratio; check for valve body leakage, clean and replace any leaking valves.
The burner cannot be ignited and maintained normally, and the burner is in a extinguished state:
Short circuits caused by deformation of the ignition electrode discharge tip prevent the burner from igniting; malfunctioning air or gas solenoid valves fail to open properly; damage to the ceramic combustion chamber, gas pipes, heat exchanger, or ceramic inner tube causes flame and gas flow blockage, preventing continuous combustion; faults in the flame detection system, loose detection circuits, or failed detection components; improper air-to-gas ratio in the combustion system can sometimes result in a popping sound upon reset. Check and adjust the position of the ignition electrode; inspect and replace faulty air or gas solenoid valves (usually due to damaged electromagnetic coils); check and replace damaged parts in the ceramic combustion chamber, gas pipes, heat exchanger, or ceramic inner tube; inspect and clean the flame detection system circuit and components; use a portable pressure gauge to measure the air and gas pressure values at the burner and adjust them to the appropriate ratio.
The above is some methods to deal with industrial burner faults, I hope it will help you
