What it is

The 1.65 x 80 A Delavan nozzle is an oil burner nozzle manufactured under the EOGB brand for use in oil-fired boiler applications. It is the component that atomises the fuel oil into a fine spray so it can be mixed with air and burned cleanly at the burner head. The nozzle is marked 1.65 x 80 A, which is the identification used when selecting and ordering the part.

Signs this part needs replacing

  • Soot deposits or visible smoke at the boiler flue during running
  • Erratic, unstable or poorly shaped flame at the burner head
  • Combustion readings that will not settle within the expected range
  • Repeated burner lockouts or difficulty establishing a flame
  • Blocked, damaged or worn nozzle tip or seat

Before you order

  • Confirm the nozzle marking on the appliance matches 1.65 x 80 A, as flow, spray angle and pattern are specific to the burner setup.
  • Check the appliance documentation or commissioning data for the nozzle specified for the boiler.
  • Inspect the nozzle holder, seat and burner assembly for damage or debris before fitting a new nozzle.
  • Order the quantity required for the service, allowing for a spare where the burner is run hard.
