Oil Burner Nozzle Spray Patterns

Hollowcone or solid cone described below refer to the tests carried out with a 600 angle at a75 mm distance from the nozzle orifice.

Nozzle injector holder. In nozzles of a 600 spray angle or less and forlow flows in particular the empty section of a hollow cone becomes smaller. This video is part of the heating and cooling series of training videos made to accompany. Describe three common spray patterns for oil burner nozzle.

Hollow cone solid cone and semisolid cone. A hollow nozzle distributes more of the oil to the outer ring of the pattern and a semi solid is neither. The purpose of the electrodes of an oil burner is to.

Oil burner nozzle spray pattern type hollow solid other. Over time the buildup of sludge and gunk inside the furnace can clog the spray nozzle. Besides nozzle rate or size in gph and spray angle there are various spray patterns such as solid core hollow core and specialty nozzles like ar anti rumble.

This one explains what the letters on the oil furnace nozzle mean. This spray pattern becomes progressively more hollow at high flow rates particularly above 800 gph. Patterns are designated as solid b hollow a and semi solid w.

The spray pattern particularly solid vs hollow core is matched to the air flow pattern of the oil burner itself. The spray nozzle sprays the oil in a pattern angle and amount specific to the make and model of the furnace. These nozzles may be used in larger burners those firing above 200 or 300 gph to provide smoother ignition.

So the nozzle whose data we showed above a delavan 800a means the nozzle sprays at an 80 degree angle with spray pattern a which we know is hollow. A solid nozzle indicates the vaporized oil is distributed evenly throughout the entire spray pattern. The spray patterns ie.

To provide the heat necessary to both vaporize the atomized oil droplet and ignite the vaporized air oil mixture.
