Product Description +

Ignition electrodes ignite the atomized fuel with a high-voltage arc flame. The position of the electrodes in relation to the nozzle is very important for igniting the flame. Electrode tips that are too far above the nozzle tip ignite the fuel well, but they come into contact with the atomized fuel and start to drip during operation. The electrodes should be 0.5-1mm above the nozzle tip. The gap between the electrode tips should be 4-5mm.

Before you order

Three things decide how well it burns

Choose the nozzle

Decide the heating power you need, then pick the matching nozzle size. The burner ships with a 25 kW nozzle as standard.

Match the compressor

A piston compressor should be at least 1200 W so it gets cooling breaks. Smaller ones switch on too often and wear out fast. The silent compressor avoids the problem.

Fit the combustion chamber

A chamber that is too large leaves cool areas where fuel does not burn out. Line it with chamotte or add a hearth pipe. Ordering the burner calibration sets the flame tube, nozzle and oil pipes to your chamber.

Frequently Asked Questions

What types of fuel can this burner handle? +
The Bairan STW series handles cooking oil, mineral oil, untreated heating oil, and filtered waste engine oil seamlessly thanks to compressed-air atomisation.
Do I need a special oil preheater? +
Yes, heavy or waste oils require proper preheating viscosity control before entering the nozzle line to ensure clean combustion.
What is the recommended compressor capacity? +
A compressor delivering at least 20 l/min at 0.4–0.8 bar stable pressure is required for optimal atomisation.
