The oil burner uses heavy oil as the raw material, and the heavy oil enters the burner in two ways, which are swirl oil and axial flow oil, similar to the internal and external air of the burner. The swirl oil is distributed in a circular shape on the outside; the axial flow oil is a columnar straight jet flow in the middle. When they reach the head of the spray gun, they converge into one road and enter the kiln through the nozzle hole of the atomized sheet for combustion. So when the fuel burner is turned off during the combustion process, how should we judge this problem? In order to deal with this problem, the following editor will share with you the reasons and treatment methods for the flameout during the combustion process of the fuel burner.
1. The reasons for the flameout of the fuel burner during the combustion process:
the
First, start the burner three times in a row. If it does not ignite and burn, it is judged as an ignition failure, and corresponding inspections are required to eliminate the failure. The blower runs normally at ignition and the program is correct.
1. If the gas source is faulty, check whether the pressure of the natural gas is normally maintained at 3-5kpa. If it is too high or too low, it will cause misfire.
2. When the burner is running normally, the fire is suddenly extinguished, which is a flameout failure. If the damper is faulty, check the size of the damper. When the damper is too large, it is easy to fail to ignite many times.
3. If the ignition electrode or ignition transformer is faulty, the ignition transformer does not ignite, or the ignition electrode is too dirty and the position is wrong, ignition failure will occur.
4. If the gas valve group is faulty, the valve group will be opened in time during normal ignition, and the sound of opening can be heard, and no flame will be established when it cannot be opened. The solution is:
5. The ignition controller is faulty. All ignition programs are issued by the controller. If the controller is damaged, it cannot be ignited normally.
6. Circuit failure, unstable power supply or lack of phase, resulting in flameout during the process. The burner does not start fault. Press the start button for a long time. The burner does not start the external chain. The external temperature or pressure control does not reach the lower limit of the start.
7. Fan motor overheat protection, reset the thermal relay. Check the start button of the control cabinet, whether it is normal.
2. The flameout treatment method of the fuel burner during the combustion process
the
1. Check the temperature or pressure setting. Adjust the natural gas pressure regulator to set the pressure.
2. The ignition controller is faulty. All ignition programs are issued by the controller. If the controller is damaged, just replace the controller in time.
3. Contact the electrician to check the power supply and wiring, check the coil of the valve group, and adjust the opening degree of the valve.
4. Test whether the ignition transformer is ignited, clean the ignition electrode, and adjust the ignition gap to maintain 2-3mm.
5. Adjust the position of the probe, clean the surface of the probe, and then restart the device. The internal interlocking of the burner does not pass. When the air pressure is too high or too low, when the air pressure switch is normally closed but not closed, and when the damper mechanism is not in place, it will all appear, and the inspection should be carried out step by step.
6. Circuit failure Check the circuit to see if the starting signal is normal and whether the voltage insurance is normal.
The above is the introduction shared by the editor about the causes and treatment methods of the flameout during the combustion process of the fuel burner. In fact, there are many reasons for the flame to go out after the burner is ignited. For example, the unstable gas source causes the flame to fluctuate and then the fire is extinguished; Or lack of phase, resulting in flameout during the process, etc. Only by knowing the causes of these occurrences, the operator can prescribe the right medicine when facing such a job!
