Delavan 00085-90b1 Oil Burner Nozzle 0.85 Gph 90 Degree

Product Description

The DELAVAN 00085-90b1 is a Type B solid-cone oil burner nozzle rated at 0.85 gallons per hour (GPH) with a 90-degree spray angle. It is designed for residential oil-fired heating systems where smooth, consistent atomization is required for reliable ignition and efficient combustion. The solid-cone spray pattern distributes fuel droplets uniformly throughout the full cone at normal residential flow rates. The nozzle body is constructed from brass with a steel orifice disc and includes a sintered filter element. It is installed by licensed oil burner technicians during routine nozzle replacement or burner tune-up service.

This nozzle is suited for residential oil burner applications operating at a rated pressure of 100 psi and an inlet fuel temperature of 80 degrees F. The Type B solid-cone pattern is well matched to mid-size residential burner heads where a uniform droplet distribution across the full spray cone supports stable flame geometry. Note that at flow rates above 8.00 GPH, the solid-cone pattern progressively becomes more hollow — this nozzle at 0.85 GPH operates well within the range where full-cone uniformity is maintained.

Key Features

• Type B solid-cone spray pattern delivers uniform droplet distribution across the full cone at 0.85 GPH
• 90-degree spray angle suits burner heads requiring a wide, even flame envelope
• Brass body with steel orifice disc for durability in oil fuel service
• Integrated sintered filter element helps trap contaminants before the orifice
• Rated at 100 psi operating pressure and 80 degrees F fuel temperature
• Manufactured under ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burners requiring a Type B solid-cone nozzle at 0.85 GPH and a 90-degree spray angle.

Installation Notes

Oil burner nozzle replacement is performed by qualified oil burner technicians, typically as part of an annual tune-up. Always shut off the burner and allow the system to cool before removing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the adapter or electrodes. After installation, verify ignition, combustion quality, and CO levels with appropriate test instruments before returning the system to service.
