Delavan 2.25-90-B Oil Burner Nozzle 2.25 Gph 90 Degree

Product Description

The DELAVAN 2.25-90-B is a solid cone Type B oil burner nozzle rated at 2.25 gallons per hour (GPH) with a 90-degree spray angle and an operating pressure of 100 psi. It is identified by a blue vial for quick field identification. Type B nozzles distribute droplets fairly uniformly throughout the full spray pattern. The pattern becomes progressively more hollow at higher flow rates, particularly above 8.00 GPH. This nozzle supports smooth ignition and efficient combustion, making it well suited for larger residential and light commercial oil-fired burner applications. Installation is performed by licensed oil burner technicians or qualified HVAC service professionals.

This nozzle is used in oil burner assemblies where a solid cone spray pattern is required for consistent atomization and combustion performance. It is a common replacement component in residential heating systems and is particularly effective in larger burner configurations where uniform droplet distribution across the full spray cone improves flame stability and combustion efficiency. The blue vial color coding helps technicians quickly confirm the correct nozzle specification during service calls.

Key Features

• 2.25 GPH flow rate for precise fuel delivery in oil burner systems
• 90-degree spray angle provides a wide, uniform solid cone pattern
• Solid cone Type B design distributes droplets uniformly throughout the complete spray pattern
• Blue vial color coding enables fast visual identification in the field
• Rated at 100 psi operating pressure for standard oil burner applications

Compatibility

Designed as an OEM-style replacement nozzle for oil burner assemblies requiring a 2.25 GPH, 90-degree solid cone Type B nozzle at 100 psi.

Installation Notes

Oil burner nozzle replacement should be performed by a licensed oil burner technician or qualified HVAC service professional. Shut down the burner and allow all components to cool before beginning service. Use a proper nozzle wrench to avoid damaging the nozzle body or electrodes, and verify that the fuel supply is shut off before removing the existing nozzle. Always follow local codes and the burner manufacturer's service procedures when replacing nozzles or adjusting the combustion head.
