Danfoss Oil nozzle 030B0211

This is a Danfoss oil nozzle, type OD B, SKU 030B0211, for use in oil burners with fuel oil. It delivers a flow rate of 1.5 GPH (5.84 kg/h) and has a spray pattern marked B. Its body is made of brass with a conical shape, and it has no safety valve. This part atomises the oil for efficient combustion and is a consumable item. It weighs 0.033 kg net and 0.034 kg gross.

Oil nozzles of this type are selected by flow rate (GPH at a reference pressure), spray angle, spray pattern (hollow, solid, or semi-solid), and thread. All three spray parameters must match the burner's data plate; a correct flow rate but wrong pattern can cause sooting, pulsation, or unstable ignition. When replacing, ensure the replacement matches the burner's stated rating, angle, and pattern. The nozzle is mounted between the oil pump and the combustion head, is not serviceable, and should be replaced at scheduled intervals or when combustion problems appear.
