Steinen Oil nozzle 1.10GPH / 60S

This item is a Steinen oil nozzle with a rated flow rate of 1.1 GPH, a 60 ° spray angle and an S spray pattern. It is used in oil-fired burners and boilers to atomise the fuel supply into a spray before combustion. The flow rate determines the volume of oil delivered through the nozzle, while the 60 ° angle sets the width of the resulting spray cone. The S pattern designates the shape of the spray distribution produced by the nozzle.

Nozzles of this type are selected by matching the flow rate, spray angle and spray pattern to the burner manufacturer's specification for the appliance. The mounting form and thread must also match the nozzle adapter or nozzle line in the burner, so the existing nozzle and its seat should be compared before ordering. The rated flow rate is stated at a reference pressure, so the pump pressure setting must correspond to the value the burner was set up for.

Nozzles of this kind commonly fail through blockage of the internal passages or the orifice by fuel contaminants, and through wear of the orifice and swirl slots, which changes the flow rate and spray shape. On the equipment this appears as poor combustion, smoke, soot deposits, an unstable or pulsating flame, or failure to ignite. Inspection typically involves checking the nozzle for blockage or damage and comparing the spray pattern and flow against the specification.
