EOGB Delavan Nozzle D04-0550-60-B

The 5.50 x 60B Delavan nozzle is an oil burner nozzle from EOGB's Delevan range, supplied under product code D04-0550-60-B. It is the component that atomises the oil supply into a fine spray at the burner head, so the fuel/air mixture burns cleanly and at a consistent rate. It is listed for use on EOGB Delevan oil-fired boiler applications.

• The burner flame is smoky, yellow-tipped or visibly unstable rather than a steady, clean shape.
• Soot builds up on the combustion head, baffles or heat exchanger between services.
• The burner becomes hard to start, runs roughly, or locks out shortly after firing.
• Fuel consumption rises for the same duty without any change to settings or controls.
• The nozzle has reached its routine service interval, or the existing unit is visibly clogged, coked or worn at the orifice.

• Read the designation stamped on the existing nozzle and confirm it matches 5.50 x 60B, as flow rate and spray pattern must match the burner's settings.
• Check the burner manufacturer's commissioning data for the nozzle specified for that appliance and output.
• Confirm the appliance model and burner type before ordering, as this nozzle is listed for EOGB Delevan applications only.
