Product Description +

Model STW133-2 is a two-nozzle burner, depending on the choice of nozzle, it can operate optimally with an output power of 50-100kW. Fuel consumption approximately 5-10 kg/h.

Suitable for use are cooking oils, mineral oils, untreated oils, waste oil etc.

Compressed air pressure for operation 0.6-0.8 bar. Air consumption 40l/min

The kit includes an oil pump, hoses, filter, mounting flange.

When selecting/assembling the burner, it is necessary to make sure what the desired heating power is and choose the appropriate nozzle size. The burner is equipped with 2x35kW nozzles as standard.

In addition, the burner requires compressed air to operate. When using a piston compressor, the compressor power should be at least 2200W to ensure cooling breaks for the compressor. Compressors with lower power will switch too frequently and wear out quickly.

It is recommended to additionally order a burner setting according to the combustion chamber. Different combustion chambers determine the length of the flame tube, the size of the nozzle, the thickness and length of the oil pipes on the burner.

The combustion chamber of the boiler also requires attention. In a combustion chamber that is too large, cool areas remain for complete combustion of the fuel. The solution is chamotte lining or an afterburning tube (hearth pipe) made of a suitable material .

It is advisable to use the burner with additional filters.

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.

Expert Knowledge

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.
