Steinen 0.65GPH, 60S nozzle

This is a Steinen oil nozzle, a precision consumable component for burners that atomise liquid fuel. Parts of this type produce a fine spray cone that mixes with combustion air in the burner head. The nozzle’s flow rate, spray angle and spray pattern together define how the flame sits in the combustion head, affecting ignition stability and combustion efficiency. The catalogue designation for this article follows the standard oil nozzle identification system, indicating its flow rating and spray characteristics, as is typical for parts of this class. When replacing an oil nozzle, the service engineer must select one with the correct flow rating (in GPH or kg/h at the reference pressure), the required spray angle (commonly between 30° and 80°), and the appropriate pattern (hollow, solid or semi-solid). A nozzle with the right rating but a wrong pattern can cause sooting, pulsation or unstable ignition, so all three parameters must match the burner data plate. This nozzle threads into the oil line between the pump and the combustion head, and it must be replaced with a clean, undamaged unit to avoid debris affecting the spray. No further technical specifications for this specific article—such as exact dimensions, pressure rating or compatibility with particular burner models—are contained in the catalogue data beyond the brand and the designation given.
