Delavan 2.75-80-b 2.75 Gph 80 Degree Type B Solid Cone Oil Burner Nozzle

Product Description

The Delavan 2.75-80-b is a Type B Solid Cone oil burner nozzle designed for residential heating systems. It delivers a flow rate of 2.75 GPH at a spray angle of 80 degrees. This nozzle produces a spray pattern that distributes fuel droplets uniformly throughout the full cone. The even droplet distribution supports smooth ignition and efficient combustion, making it a reliable choice for larger residential oil burners. At flow rates above 8.00 GPH, the solid cone pattern becomes progressively more hollow, but at 2.75 GPH it performs consistently and predictably. The brass body construction provides durability and resistance to corrosion in fuel oil environments. The steel orifice disc maintains a precise spray geometry over extended service cycles. A built-in Monel strainer filters contaminants from the fuel supply before they reach the orifice, helping protect burner performance and extend nozzle service life. This nozzle is rated for operation at 100 PSI and is manufactured under ISO 9001 quality standards. HVAC technicians and oil burner service professionals rely on Delavan nozzles for consistent performance during seasonal tune-ups, burner replacements, and heating system installations. The 2.75-80-b fits standard residential oil burner heads and is a direct replacement in systems requiring a 2.75 GPH, 80 degree, Type B solid cone nozzle. Proper nozzle selection is critical to combustion efficiency, flame stability, and emissions control. Using the correct flow rate and spray angle for the burner model ensures complete atomization of the fuel and reduces soot buildup in the combustion chamber. This nozzle supports clean, stable operation in forced-air oil furnaces and oil-fired boilers used in residential heating applications.
