Causes of failures of oil-fired boiler burners and their treatment methods:
Failure phenomenon, cause and treatment method:
1. The ignition rod of the burner does not ignite
the reason:
1. There is carbon slag and oil stains in the gap of the ignition rod
2. The ignition rod is broken, damp, and leaking
3. The distance between the ignition rods is wrong, too long or short
4. The insulation skin of the ignition rod is damaged and short-circuited to the ground
5. Ignition cable and transformer failure: the cable is disconnected, and the connector is damaged, causing a short circuit during ignition; the transformer is disconnected or other faults occur
Treatment method: 1. Clear. 2. Replace with a new one. 3. Adjust the distance. 4. Change the line. 5. Change the line and change the transformer
2. The ignition rod has sparks but does not ignite
The reason:
1. The ventilation gap of the cyclone is blocked by carbon deposits, and the ventilation is poor
2. The oil nozzle is dirty, blocked or worn
3. The throttle setting angle is too small
4. The distance between the tip of the ignition rod and the front edge of the oil nozzle is not appropriate (too protruding or retracting)
5. The solenoid valve of the first oil gun is blocked by debris (small oil gun)
6. The oil is too viscous to flow easily, or the filter system is blocked or the oil valve is not opened, which makes the oil pump insufficient and low oil pressure
7. The filter screen of the oil pump itself is blocked
8. The oil contains more water (abnormal sound of boiling in the heater)
Approach:
1. Clear
2. Clean first, if not possible, replace with a new one
3. Turn down test
4. Adjust the distance (3~4mm is better)
5. Remove and clean (clean the parts with diesel)
6. Check pipelines and oil filters, heat preservation equipment
7. Remove the peripheral screws of the oil pump, carefully remove the outer cover, take out the oil net inside, and soak with diesel oil
8. Change to a new oil and test it
