Oil Burner Nozzle

When thinking about your oil burning needs one of the crucial parts to consider is the Oil Nozzle. Considering the characteristics of the fuel, combustion, oil pressures and how the oil is atomised when sprayed. Nozzles are key to efficient, clean, stable and economic combustion.

Danfoss oil nozzles are renowned for their high quality and precision, out-performing other nozzles in oil atomisation and consistency. Built to meet requirements of effective atomising, accurate dosing, constant spray pattern and angle, the Danfoss oil nozzle is a precision part.

How does my Oil Nozzle work?
Oil enters the nozzle though a filter, through the bottom screw and side holes. The oil then runs along the inner-side of the cone and into the cone slots. Under high pressure the oil is forced through the slots and into the swirl chamber converting some of the pressure into rotational energy. The oil gains its rotary motion in the swirl chamber and the oil film is formed as a ‘tube’ then forced through the orifice and breaking up into small ‘atomised’ drops for combustion.

Performance and Pressure
The performance of any nozzle will depend on the atomizing pressure – this is the pressure the oil has when entering the nozzle. Altering the pressure will also alter the characteristic of the nozzle so make sure to check the oil pressure with a reliable oil gauge as oil consumption is dependent on the atomizing pressure.

Spray Patterns and Spray Angles
Every Danfoss nozzle has the spray properties marked directly on the nozzle itself. Available with varying spray patterns and angles the right nozzle must fit the specifications of the burners combustion chamber. Danfoss oil nozzle spray patterns are specified as S, H and B. S for Solid, H for Hollow and B for a semi solid universal designation. The spray angles are normally, 30, 45, 60 and 80 degrees. If in doubt, due to lack of technical information, it is usually best its start with a 60degree spray angle and S pattern nozzle.
