EOGB 5.00 X 80 B Delavan Nozzle D04-0500-80-B

The 5.00 X 80 B Delavan Nozzle is an oil burner nozzle supplied under the EOGB brand for the EOGB Delevan appliance family. It meters and atomises the oil supply at the burner head so that combustion air and fuel mix correctly. The 5.00 x 80 B designation marked on the nozzle identifies the flow rating, spray angle and spray pattern type required by the burner.

• The burner flame is unstable, pulsing or failing to establish reliably at start-up.
• Combustion readings drift outside the values set at commissioning, with rising CO or smoke number.
• Soot deposits build up on the burner head, baffles or heat exchanger.
• The nozzle is visibly clogged, damaged or has been in service beyond the burner manufacturer's service interval.

• Check the nozzle marking currently fitted against the 5.00 x 80 B rating, spray angle and pattern required by the burner manufacturer's data plate or commissioning sheet.
• Confirm the appliance is an EOGB Delevan unit before ordering.
• Allow for a combustion analysis and re-commissioning after fitting, as a change of nozzle affects the set combustion figures.
