  	What failures will occur when the gas boiler burner is running?
What failures will occur when the gas boiler burner is running? 1. The ignition rod of the burner does not ignite    (1), reason:    1. There is carbon residue and greasy dirt 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 insulating sheath of the ignition rod is damaged and shortcircuited 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.    (2). Treatment measures:   Clear, renew, adjust distance, change line, change transformer.   2, the ignition rod has sparks but does not ignite    (1), reason:    1. The ventilation gap of the cyclone is blocked by carbon deposits, and the ventilation is poor.   2. The oil nozzle is dirty, clogged or worn.    3. The setting angle of the damper 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 fire 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).    (2). Treatment measures: Removal; clean first, if not possible, replace with a new one; adjust a small test; adjust the distance (3~4mm is better); remove and clean (clean the parts with diesel); check the pipeline, oil filter, and heat preservation equipment; remove the oil pump For the peripheral screws, carefully remove the outer cover and take out the oil net inside, soak it with diesel oil; replace it with a new oil and try it.   3, when the small fire is normal but turned to the big one, it goes out or flickers unsteadily    (1), reason:    1. The air volume of the damper of the fire is too large.   2. The oil valve micro switch (the outermost group of the damper) of the high fire is set improperly (the air volume of the damper is set larger than that of the high fire).   3. The oil viscosity is too high and difficult to atomize (heavy oil).    4. The distance between the cyclone and the nozzle is improper.    5. The oil nozzle of the large fire is worn or dirty.   6. ​​The heating temperature of the reserve oil tank is too high, causing the steam to make the oil pumping unsmooth.    7. The oil in the oilfired boiler contains water.    (2). Treatment measures:    Gradually reduce the test; increase the heating temperature; adjust the distance (between 0 and 10 mm); clean or replace; set about 50; change the oil or drain.    4. Burner noise increases    (1), reason:    1. The shutoff valve in the oil circuit is closed or the oil intake is insufficient, and the oil filter is blocked.    2. The oil inlet temperature is low, the viscosity is too high, or the pump oil inlet temperature is too high.    3. The oil pump is malfunctioning.    4. The bearing of the fan motor is damaged.    5. The fan impeller is too dirty.    (two), processing method:    Check whether the valve in the oil pipeline is open, whether the oil filter is working properly, clean the filter screen of the pump itself; increase the oil temperature or reduce the oil temperature; replace the oil pump; replace the motor or bearing; clean the fan impeller.
