The DELAVAN 100-80b1 is a Type B solid cone oil burner nozzle rated at 1.0 gallon per hour (GPH) with an 80-degree spray angle. It atomizes fuel oil into a fine, uniform cone-shaped pattern for combustion in residential and light commercial oil-fired heating equipment. The solid cone pattern delivers fuel evenly across the full spray area, making it well suited for burners that require consistent flame geometry. HVAC technicians and oil burner service professionals install this nozzle as part of routine annual maintenance or combustion tune-up procedures.
This nozzle is used in oil-fired forced-air furnaces, boilers, and water heaters that require a solid cone spray pattern. The 80-degree angle is a wide-angle configuration commonly specified for pressure-gun burners where the combustion chamber geometry calls for a broad, short flame. A 1.0 GPH flow rate corresponds to approximately 140,000 BTU/h of fuel delivery at standard operating pressure, making it appropriate for mid-range residential heating systems. Always verify the burner manufacturer's nozzle specification before installation.
Designed as an OEM-style replacement nozzle for residential and light commercial oil-fired burners requiring a 1.0 GPH, 80-degree solid cone nozzle. Always cross-reference the burner manufacturer's nozzle specification sheet to confirm the correct flow rate, angle, and spray pattern before replacing.
Oil burner nozzles are installed by qualified oil heat technicians as part of combustion system service. 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 during removal and installation. Combustion performance should be verified with a combustion analyzer after nozzle replacement to confirm CO2, stack temperature, and smoke number are within acceptable limits.
