Steinen 11.00GPH, 60SS nozzle

An oil nozzle atomises fuel oil into a fine spray so that it can mix with combustion air and burn completely. Nozzles of this type are precision, consumable parts; the flow rate, spray angle and spray pattern together define how the flame sits in the combustion head. Selection depends on the burner data plate: flow rate in GPH or kg/h at the reference pressure, spray angle (typically 30–80 degrees) and pattern (hollow, solid or semi-solid). A nozzle of the correct flow rate but wrong pattern can cause sooting, pulsation or unstable ignition; all three parameters must match the burner specification. This specific article is a Steinen oil nozzle identified by the designation 11.00GPH, 60SS, and carries the catalogue number 908.892.011. The notation follows the standard convention used in the trade: the first figure indicates the flow rate, the second the spray angle, and the letter code the spray pattern and thread type. For a replacement, confirm that the flow rate, angle and pattern match the existing nozzle. If the old nozzle body or thread is damaged, check the thread size before fitting. Always replace the nozzle gasket or sealing washer, and ensure the nozzle is torqued to the manufacturer’s recommended value – overtightening can distort the orifice.
