I. the ignition rod of the burner of gas boiler does not ignite
Reason: 1 point of the fire rod gap with carbon slag, oil.
The firebar breaks at 2.Damp.The leakage.
The distance between the 3 fire rods is not right, too long or too short.
4 fire rod insulation damage, short circuit to the ground.
5. Ignition cable and transformer failure: cable break, connector damage, resulting in short circuit during ignition;Transformer disconnection or other fault.
The treatment measures are as follows: clear, renew, adjust the distance, change the line, change the transformer.
Two, gas boiler ignition rod spark but not fire
Reason: 1 cyclone ventilation gap is blocked by carbon accumulation, poor ventilation.
The oil nozzle is not clean, blocked or worn.
The throttle setting Angle is too small.
Improper distance between the tip of the 4-point firerod and the leading edge of the oil nozzle (too prominent or indented)
The first oil gun solenoid valve is blocked by sundries (small oil gun).
6 oil is too viscous flow is not easy or the filtration system is blocked or the oil valve is not open, so that the oil pump oil absorption is insufficient, low oil pressure.
The filter screen of the oil pump itself is blocked.
The oil contains more water (abnormal boiling sound in the heater).
Treatment measures are: removal;Clean first, if not replace;Small test;Adjust the distance (3~4mm is better);Remove and clean (clean the parts with diesel oil);Check pipeline, oil filter, insulation equipment;Remove the outer screw of the oil pump, carefully remove the outer cover and take out the oil net inside, and soak it with diesel oil;Try a new oil.
Three, gas boiler small fire normal and turn the big fire, out or flame flickering instability.
Reason: 1. The damper air volume of the fire was set too large.
The fretting switch of the oil valve in fire (the outer part of the damper) is not properly set (the air volume is larger than that of the damper in fire).
Oil viscosity is too high and not easy to atomize (heavy oil).
Improper spacing between cyclone disc and nozzle.
Fire grease nozzle is worn or dirty.
The heating temperature of the reserve oil tank is too high, which causes the steam to make the oil delivery from the oil pump not suitable.
The oil in the oil-fired boiler contains water.
Treatment: gradually reduce the test;Raise the heating temperature;Adjust the distance (between 0 and 10mm);Clean or replace;About 50℃ can be set;Oil change or drain.
Fourth, gas boiler burner noise increases
Reason: 1 in the oil line, the globe valve is closed or the oil intake is insufficient, the oil filter is blocked.
Low inlet temperature, high viscosity or too high pump inlet temperature.
The oil pump is out of order.
Fan motor bearing damaged.
The fan impeller is too dirty.
Treatment: (1) check whether the valve in the pipeline is open, whether the oil filter is normal, clean the filter screen of the pump itself.Increase or decrease the oil temperature.Replace the oil pump.Replace the motor or bearing.Clean the impeller of the fan.
