Troubles and Treatment Methods of Gas Boiler Combustor

I The reason why the ignition rod of gas boiler burner is not ignited: 1 There is carbon slag and oil dirt in the gap between ignition rods 2 The ignition rod is broken, wet and leaking 3 The distance between ignition rods is not right, too long or too short 4 The insulating sheath of the ignition rod is damaged and short circuited to the ground 5 Failure of ignition cable and transformer: the cable is broken, and the connector is damaged, causing short circuit during ignition; the transformer is broken or has other faults There are five ways to deal with it: clearing, renewing, adjusting distance, changing line, changing transformer 2 The ignition rod of the gas boiler has sparks but does not ignite 1 The ventilation gap of the cyclone disk is blocked by carbon deposition and the ventilation is poor 2 The oil nozzle is dirty, blocked or worn 3 The setting angle of damper is too small 4 The distance between the ignition rod and the front edge of the oil nozzle is improper (too protruding or shrinking) 5 * the oil gun solenoid valve is blocked by sundries (small oil gun) 6 The oil quality is too viscous to flow easily or the filter system is blocked or the oil valve is not opened, so that the oil pump has insufficient oil absorption and low oil pressure 7 The filter screen of the oil pump is blocked 8 There is much water in the oil (abnormal sound of boiling in the heater) The treatment measures include: clearing; cleaning first, if not replacing; reducing the test; adjusting the distance (3-4mm is better); removing and cleaning (clean the parts with diesel); checking the pipeline, oil filter and heat preservation equipment; removing the peripheral screws of the oil pump, carefully taking off the outer cover and taking out the oil net inside, and soaking with diesel; changing the oil for test III when the gas boiler turns from a small fire to a large fire due to normal operation, it will go out or flicker unsteadily 1 The air volume of the air door of the large fire is set too large 2 The oil valve microswitch of the fire (the group other than the damper Zui) is not set properly (it is set to be larger than the air volume of the damper of the fire) 3 Oil viscosity is too high to be atomized (heavy oil) 4 The distance between the cyclone disk and the oil nozzle is improper 5 The oil nozzle is worn or dirty 6 The heating temperature of the preparation oil tank is too high, which causes the steam to make the oil pump not smoothly 7 The oil in the oil boiler contains water 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 oil or drain 4 Reasons for the increase of burner noise of gas boiler: 1 The stop valve in the oil circuit is closed or the oil inlet quantity 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 faulty 4 Fan motor bearing is damaged 5 The fan impeller is too dirty Treatment: ① check whether the valve in the oil pipeline is open, whether the oil filter works normally, and clean the filter screen of the pump itself ② Increase or decrease the oil temperature ③ Replace the oil pump ④ Replace the motor or bearing ⑤ Clean the fan impeller.
