Common faults of steam boiler combustor

 Steam boiler burner

fuel Steam boiler In the long-term use of the combustion engine, it is inevitable that some small failures will occur. If it can not be solved in time, it will inevitably affect the normal operation of the shop. So, what are the common faults of oil fired boiler combustion engine? In the face of these faults, how should we solve them? Let's take a look at Danone!

The burner starts and injects oil, but there is no spark between the ignition electrodes (the fault red light is on)

  Fault analysis: When the ignition circuit is interrupted, the lead wire of the ignition transformer fails due to a long time. The wire contact of the ignition transformer is poor, the ignition transformer is broken, the distance between the ignition electrodes is incorrect, the electrodes discharge to the ground, and there is no spark between the two electrode heads. The reason is that the insulation ceramic of the ignition electrode is cracked or dirty, and the carbon slag is formed.

resolvent: Check the whole circuit, replace, rewire, adjust, clean or replace

The burner is started, there is ignition spark, but no oil injection (fault red light is on)

Fault analysis: The fuel does not reach the oil pump, there is no oil in the oil tank, the valve on the oil suction pipe is not opened, the nozzle is blocked, the motor turns in the opposite direction, the oil pump fails, the filter of the oil tank preheater is blocked, the solenoid valve fails, the atomization device fails, the oil pressure is too low, the photosensitive resistance is damp or the external light is too bright (the resistance value of photosensitive resistance is too small).

resolvent: Check the oil suction pipe, fill with oil, open the valve, clean, replace any two wiring, repair or replace, clean, repair or replace, overhaul or replace, adjust the height, blow dry or weaken the external light

The burner ignites and then goes out automatically after a few seconds (fault red light is on)

Fault analysis: Photosensitive resistance is blocked or lampblack pollution, poor ventilation, photosensitive resistance circuit interruption, stable combustion disc and burner head dirty

resolvent: Clean or replace, check the opening of air and smoke valves, replace circuit wires, and clean

There are sparks in the combustion, but the flame is not good

  Fault analysis: The fuel is too cold, the atomization pressure is too low or too high, the combustion air is too much, the nozzle is blocked, dirty or worn, there is water in the oil, the oil suction pipe may not be sealed or blocked, and the fuel quantity is insufficient

resolvent: Adjust the thermostat of the preheater, increase the temperature, adjust, reduce, clean or replace according to the required value, remove water or change oil, check the air tightness of pipes and valves, dredge the pipes and supplement the oil quantity
