EOGB Delavan Nozzle 2.25 x 60 B

The EOGB Delavan Nozzle 2.25 x 60 B is a pressure-jet atomising nozzle used in oil-fired boiler burners. It is listed by EOGB under the Delevan model group and carries the part number D04-0225-60-B. Its role is to atomise the oil supply into a fine spray so the burner can produce a clean, stable flame.

• The flame becomes ragged, unstable or noisy, or fails to establish cleanly on start-up.
• Soot deposits appear on the burner head, baffles or heat exchanger surfaces.
• Smoke readings rise or combustion analysis drifts outside the expected range.
• Oil consumption increases without a change in demand or settings.
• The nozzle body, strainer or orifice shows visible contamination, damage or wear when inspected.

• Check the markings on the existing nozzle against the 2.25 x 60 B designation, as the flow rate and spray pattern must match.
• Confirm the appliance is an EOGB Delevan unit before ordering.
• Verify the nozzle thread, body length and any required filter or strainer arrangement on the burner.
• Have the burner's combustion settings checked and reset after fitting.
