EOGB 0.75 x 80 W EN Europe Nozzle

The 0.75 x 80 W EN Europe Nozzle is an oil burner nozzle manufactured by EOGB for use on Delevan-pattern burners. It meters and atomises the fuel supply at the burner head, and its designation sets the flow rate and spray characteristics the burner is set up to run. It is a service item on EOGB boiler plant.

• The flame becomes ragged, unstable or slow to establish at start-up.
• Soot deposits appear on the burner head, baffles or heat exchanger surfaces.
• Combustion readings drift and cannot be brought back within limits by normal adjustment.
• The nozzle body or its strainer is visibly blocked, damaged or worn at the orifice.
• Fuel consumption rises without a change in demand or settings.

• Confirm the nozzle designation stamped on the existing nozzle matches 0.75 x 80 W EN Europe.
• Check the burner is an EOGB Delevan unit before ordering, as nozzle flow and spray angle are burner-specific.
• Verify the appliance has not been converted or re-rated, which would change the nozzle required.
• Have the combustion analyser and any gaskets or seals needed for the burner reassembly to hand before starting the swap.
