What it is
This is an 8.50 X 45 B Delavan nozzle manufactured by EOGB, part number D04-0850-45-B. It is a pressure-jet atomising nozzle used in oil-fired boiler and burner assemblies, where it meters and atomises the fuel supply to produce a stable, correctly shaped flame in the combustion chamber.
Signs this part needs replacing
- Burner flame becomes unstable, uneven or difficult to establish
- Visible smoke at the flue or soot building up on the heat exchanger
- Combustion readings drifting outside the tolerance set at commissioning
- Restricted or blocked nozzle giving poor atomisation and erratic firing
- Increased fuel consumption without a change in heat demand
Before you order
- Confirm the nozzle stamping matches 8.50, 45 and B before removing the existing nozzle
- Check the burner data plate and commissioning record for the required nozzle rating and spray pattern
- Check the nozzle holder and fuel supply for contamination before fitting a new nozzle
