What it is
The 5.50 X 45B Delavan Nozzle is an oil burner nozzle supplied under the EOGB brand from the Delavan range. It fits oil-fired boiler appliances and is the component that atomises fuel oil into a fine spray for combustion at the burner head. The nozzle is identified by its 5.50 X 45B rating, which must match the specification of the appliance it is fitted to.
Signs this part needs replacing
- Sooty deposits or black smoke at the appliance, indicating poor atomisation
- Unstable or pulsating flame, or repeated lockouts on ignition
- Rising fuel consumption without a change in demand
- Carbon build-up on the burner head or nozzle face
- Combustion readings drifting outside the appliance manufacturer's limits
Before you order
- Read the markings on the existing nozzle and confirm they match the 5.50 X 45B rating and pattern
- Check the boiler or burner manufacturer's specification for the nozzle required by that appliance
- Confirm the burner accepts a Delavan-pattern nozzle of this rating before fitting
- Have the combustion analyser to hand so the appliance can be set up and checked after replacement
