Imprimer la pageAdjustment of flame length (shown by green arrow). After the flow is stable and normal, the flame
length can be adjusted according to the process requirements. It is necessary to loosen the locking
copper screw at the end of the screw rod in advance. If you need to extend the flame length, you
can turn the flame length adjustment knob backwards, and the flame length becomes longer. If you
need to shorten the flame length, you can turn the flame length adjustment knob forward to
shorten the flame length.
The flame length is too short:
1. The tip may be clogged. Remove for cleaning.
2. Increase the gas (fuel) flow or reduce the flow of atomized air (for fuel burners only).
The flame length is too long: reduce the gas (fuel) flow or increase the flow of atomizing air (for oil
burners only).
The flame appeared smoky. Possible reasons:
1. Combustion air flow is too low.
2. The ratio of air to fuel (fuel) is too low.
3. Atomizing gas flow (for fuel burners only) is too low.
4.6 Atomizing nozzle adjustment (for oil burners only)
Flame shape and appearance are also affected by the relative position of the fuel nozzle / atomizing
nozzle. As described above, in operation, the fuel nozzle is initially set to rotate backward from the
flush position with respect to the atomizing hood tip by 1 turn.
Turning the oil core clockwise will bring the fuel nozzle closer to the flush position of the tip of the
atomizing gas hood, which will reduce the atomizing air flow and may prolong the flame. Rotating
the oil tip in the opposite direction increases the atomizing airflow and may shorten the flame. It is
recommended that the operator test the tip operating position and the atomizing air pressure to
determine the optimal setting for actual operating conditions.
If there are bulk deposits inside and the flame is deflected, the burner blocks need to be cleaned.
During start-up, the burner tubing may need to be removed and cleaned multiple times. With the
reduction of dirt and assembly debris in the pipeline, after one or two days, the frequency of
removal and cleaning will be significantly reduced
4.7 Burner maintenance
The burner requires regular inspection. Inspection after long periods of non-use is particularly
important.
During the first month of burner operation, the nozzles need to be inspected weekly. In the second
month, the frequency of inspections can be extended to once every two weeks. Anderson
recommends that each nozzle be inspected at least monthly. At each inspection, the burner needs
to be removed from the combustion air duct in order to fully check the status of the burner.
