What faults may occur during the operation of gas-fired burners and what are the treatment methods?
What faults may occur during the operation of gas-fired burners and what are the treatment methods?
1. The ignition electrode does not ignite
(1) Reason:
1. The ignition electrode gap is stuck with carbon chips and oil stains.
2. The ignition electrode is broken, damp, and short-circuited.
3. The distance between the ignition electrodes is incorrect, too long, or too short.
4. The insulation jacket of the ignition electrode has damage, causing a short circuit to the ground.
5. There are malfunctions in the ignition cable and transformer: the cable breaks, the connector breaks, and a short circuit occurs during ignition;
The transformer breaks or has other malfunctions.
(2) Treatment measures:
Clear, replace, adjust the distance, replace the line, and replace the transformer.
2. The ignition electrode has sparks but cannot ignite
(1) Reason:
1. The ventilation gap of the swirl disk is blocked by carbon deposition, and the ventilation is poor.
2. The fuel nozzle is unclean, blocked, or worn.
3. The setting angle of the air damper is too small.
4. The distance between the tip of the ignition electrode and the front edge of the fuel nozzle is not appropriate (too prominent or retracted).
5. The electromagnetic valve of the first oil gun is blocked by debris (small oil gun).
6. The oil is too viscous and difficult to flow or the filtration system is blocked, or the oil valve is not open, causing the oil pump to suck in insufficient oil, and the oil pressure is low.
7. The oil filter of the oil pump is blocked.
8. The oil contains more water (boiling noise in the heater).
(2) Treatment measures:
Clear; first clean, if not replace; adjust and test; adjust the distance (3-4mm is good); remove and clean (use diesel to clean the parts); check the pipeline and oil filter, insulation equipment; remove the outer screws of the oil pump, carefully remove the cover and take out the oil net inside, use diesel to soak and clean; replace the new oil for testing.
3. The small fire is normal and when the big fire is turned on, it extinguishes or flickers
(1) Reason:
1. The air flow setting of the big fire damper is too large.
2. The microswitch setting of the oil valve of the big fire (the outermost group of the damper) is not appropriate (set larger than the air flow of the big fire damper).
3. The oil viscosity is too high and difficult to atomize (heavy oil).
4. The distance between the swirl disk and the fuel nozzle is inappropriate.
5. The fuel nozzle is worn or dirty.
6. The preheating temperature of the auxiliary oil tank is too high, causing the steam to make the oil pump deliver oil unsmoothly.
7. There is water in the oil of the oil-fired boiler.
(2) Treatment measures:
Gradually reduce and test; increase the heating temperature; adjust the distance (within 0-10mm); clean or replace; set around 50; replace the oil or drain the water.
4. The noise of the burner increases
(1) Reason:
1. The oil valve is closed or the oil supply is insufficient, and the oil filter is blocked.
2. The inlet temperature of the oil is low, the viscosity is too high, or the inlet temperature of the pump is too high.
3. There is a malfunction in the oil pump.
4. The bearing of the fan motor is damaged.
5. The fan blades are too dirty.
(2) Treatment method:
Check whether the valve in the oil pipeline is open, whether the oil filter is working properly, and clean the filter screen of the pump itself; Heating or lowering the oil temperature; Replace the oil pump; Replace the motor or bearing; Clean the fan impeller.
