Delavan 0.90-70-B Oil Burner Nozzle 0.9 Gph 70 Degree

Product Description

The DELAVAN 0.90-70-B is a solid-cone Type B oil burner nozzle rated at 0.9 gallons per hour (GPH) with a 70-degree spray angle and a 100 psi operating pressure. It is designed to atomize fuel oil into a finely distributed spray pattern for use in residential and light commercial oil-fired heating equipment. The solid-cone spray distributes droplets uniformly throughout the full pattern at this flow rate, supporting smooth ignition and efficient combustion. Licensed oil burner technicians and HVAC service professionals install and replace this nozzle as part of routine annual tune-ups or combustion system servicing.

This nozzle is suited for oil burners where a solid-cone pattern is specified by the equipment manufacturer or combustion analysis indicates a need for uniform droplet distribution across the full spray cone. It is particularly well matched to larger burner applications where smooth ignition characteristics are a priority. The 70-degree angle is a common specification in residential forced-air oil furnaces and oil-fired boilers. The blue vial color coding identifies the 70-degree spray angle for quick identification during service calls.

Key Features

• 0.9 GPH flow rate for precise fuel delivery at rated firing rate
• 70-degree spray angle suits a wide range of residential oil burner configurations
• Solid-cone Type B pattern distributes droplets uniformly throughout the full spray pattern
• 100 psi rated operating pressure
• Blue vial color coding identifies the 70-degree angle at a glance
• Supports smooth ignition and efficient combustion, particularly in larger burners

Compatibility

Designed as an OEM-style replacement nozzle for oil burners requiring a 0.9 GPH, 70-degree solid-cone Type B nozzle at 100 psi. Verify the burner manufacturer specification sheet or combustion report before substituting nozzle type, flow rate, or spray angle.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Shut down the burner and allow the system to cool before removing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes. After installation, perform a combustion analysis with calibrated test equipment to confirm CO2, oxygen, and smoke readings are within acceptable limits before returning the system to service.
