EOGB Delevan 3.50 x 45 A Nozzle D04-0350-45-A

The 3.50 x 45 A Delevan nozzle is a burner nozzle manufactured by EOGB for use within the EOGB Delevan range. It meters and atomises the fuel supply at the burner head, producing the spray pattern required for controlled combustion. It is a service item, so condition directly affects flame quality and combustion efficiency.

• Sooty or smoky combustion with visible deposits around the burner and heat exchanger
• An unstable or pulsating flame that will not settle at the correct setting
• Rising fuel consumption without a change in demand or settings
• Difficult or delayed ignition at the start of a firing cycle
• Poor combustion readings that cannot be corrected by adjustment alone

• Confirm the existing nozzle marking matches 3.50 x 45 A before removal, as flow rate, spray angle and pattern must all correspond
• Check the burner and boiler documentation to verify the correct nozzle designation for the appliance
• Inspect the nozzle holder, electrode positions and seals while the burner is stripped, as these affect spray quality
• Have the combustion readings checked and the burner re-commissioned after fitting, since nozzle changes alter combustion settings
