Buse hp-Technik M2-P, jaune

An oil nozzle is a precision component that atomises fuel oil into a fine conical spray so that it can mix with combustion air and burn completely. It is fitted at the end of the burner’s blast tube, facing into the combustion head. The nozzle is a consumable part: its flow rate, spray angle and spray pattern together determine how the flame sits relative to the air stream. For correct burner operation, all three parameters must match the data given on the burner’s rating plate. A nozzle with the right flow rate but the wrong pattern can cause sooting, flame pulsation or unstable ignition. Selection of an oil nozzle is based on three characteristics: flow rating (in US GPH or kg/h at a reference pressure, usually 7 bar or 10 bar), spray angle (commonly 30° to 80°) and spray pattern (hollow cone, solid cone or semi-solid cone). The thread is standard (1/8" BSP or NPT, depending on the burner). When replacing a nozzle, always check the burner manufacturer’s specification for these three values. Never rely on the colour coding alone, as colour codes vary between brands and are not a reliable substitute for the printed rating. This article is the hp-Technik M2-P nozzle, yellow. The catalogue article number is 543.892.001; manufacturer codes are 0989999, 84169000 and 543.892.001. It belongs to the hp-Technik brand and is listed in the oil nozzles category. Beyond the name, codes and brand, no further specific properties are given for this particular nozzle. For correct selection and replacement, refer to the flow rating, spray angle and pattern printed on the packaging or on the nozzle body itself.
