What it is

The 4.50 X 45 W Delavan Nozzle is an EOGB oil burner nozzle from the Delavan range, intended for oil-fired boiler applications. It meters and atomises the fuel at the burner, and the reference in its name sets out the nozzle sizing, the 45-degree spray angle and the W spray pattern. Nozzle selection determines the shape and quality of the flame produced at the combustion head.

Signs this part needs replacing

  • Soot deposits or persistent dark smoke at the flue
  • An unstable, pulsing or erratic flame at the burner
  • Rising CO readings or a failed combustion analysis
  • Fuel dribbling from the nozzle after burner shutdown
  • Rough or noisy burner start-up

Before you order

  • Check the markings on the existing nozzle and confirm they match 4.50 X 45 W.
  • Check the burner or appliance data plate for the nozzle size and spray angle the setup requires.
  • Confirm the spray pattern designation called for by the burner manufacturer.
  • Inspect the oil line and filter for contamination when fitting a new nozzle.
