EOGB Delevan Nozzle 7.00 x 30 B

The 7.00 x 30 B Delevan nozzle is an oil burner nozzle supplied by EOGB under the Delevan range. It is the atomising component that the burner uses to deliver fuel into the combustion chamber in the required spray form. It is listed by the manufacturer for use on EOGB Delevan boiler applications.

• The burner flame becomes uneven, lazy or visibly altered in shape and colour.
• Soot deposits build up on the combustion head, baffles or heat exchanger surfaces.
• Combustion readings drift outside the figures recorded at the last service, with rising CO or smoke number.
• The burner becomes difficult to light or locks out intermittently.
• Fuel consumption rises without a change in demand or settings.

• Read the designation stamped on the existing nozzle and confirm it matches 7.00 x 30 B exactly.
• Confirm the burner and boiler model against the appliance data plate before ordering.
• Check the nozzle holder, electrode assembly and leads at the same time, as these are disturbed when the nozzle is changed.
• Refer to the burner manufacturer's commissioning data for the correct nozzle for the appliance and its intended firing rate.
