Steinen Oil nozzle 9.00GPH / 45SS

The Steinen Oil nozzle 9.00GPH / 45SS is an oil burner nozzle with a flow rate of 9 GPH, a 45 ° spray angle, and an SS spray pattern. It is used to atomize fuel oil into a fine spray for combustion in oil-fired burners and boilers. The 45 ° angle directs the spray cone relative to the nozzle axis, and the SS pattern defines the shape of the spray distribution. The rated flow of 9 GPH specifies the volume of oil delivered per hour at the nozzle's rated pressure.

Nozzles of this type are selected by matching the required flow rate, spray angle, and spray pattern to the burner manufacturer's specification. The mounting form must match the burner's nozzle adapter, typically a standard threaded body, and the nozzle seat must be clean and undamaged before installation. Before ordering, compare the existing nozzle's markings and the burner nameplate data to confirm the flow rate, angle, and pattern. The nozzle is installed finger-tight and then tightened to the torque specified by the burner manufacturer, with the electrode position and gap checked afterward.

Nozzles of this kind commonly fail by clogging, wear of the orifice, or a distorted spray pattern. When this happens, the burner may show a smoky flame, delayed ignition, pulsating combustion, or a rise in fuel consumption. A blocked or worn nozzle can also cause carbon buildup on the electrodes and flame sensor, leading to lockout. Check the nozzle strainer, the oil pressure, and the spray pattern during routine service, and replace the nozzle if the pattern is uneven or the flow rate is out of specification.
