Dysza Monarch 5.00GPH, 60PLP

This oil nozzle is a consumable component that atomises fuel oil into a fine spray for complete combustion. It sits at the front of the burner, fitted into the combustion head. The spray angle and pattern – hollow, solid or semi-solid – together with the flow rate determine how the flame sits in the head and interacts with the air stream. Selecting a nozzle by flow rate alone is not enough: if the spray pattern or angle does not match the burner design, the flame may soot, pulsate or fail to ignite reliably. All three parameters must be taken from the burner data plate. This article is a Monarch oil nozzle with a flow rating of 5.00 GPH and the model designation 60PLP. Parts of this type are precision‑manufactured and should be replaced with an identical specification. When sourcing a replacement, always verify the flow rate, spray angle and pattern against the burner manufacturer’s recommendation. The nozzle thread and the reference pressure under which the rating is stated must also be checked – both are standardised but not universally identical across all burner brands.
