The Delavan 2.50-60-w is a Type W Semi-Hollow Cone oil burner nozzle rated at 2.50 gallons per hour with a 60-degree spray angle. This nozzle is designed for residential and light commercial oil-fired heating equipment, including forced-air furnaces, boilers, and water heaters that run on No. 1 or No. 2 fuel oil. Delavan is one of the most recognized names in oil burner nozzle manufacturing, and their Type W pattern is a widely specified choice across the HVAC industry for its reliable atomization performance. The semi-hollow cone spray pattern produces a fire pattern that is denser at the outer edges with a partially filled center. This makes it well suited for pressure-atomizing gun-type oil burners where proper flame shape and combustion efficiency are critical. At 2.50 GPH, this nozzle delivers a precise fuel flow rate that must match the burner manufacturer specifications to ensure correct heat output and system efficiency. Installing the correct nozzle flow rate and spray angle is essential during annual oil burner tune-ups, combustion analysis, and heating system maintenance. HVAC technicians and oil burner service professionals rely on Delavan nozzles for consistent performance, tight flow tolerances, and dependable atomization across a wide range of operating pressures. The standard operating pressure for this type of nozzle is 100 PSI, which is typical for residential oil burner applications. Proper nozzle selection affects stack temperature, CO2 levels, smoke number, and overall combustion efficiency. Replacing the nozzle annually is a best practice in preventive maintenance for oil heating systems. This nozzle is a direct replacement for systems originally specified with a 2.50 GPH, 60-degree, Type W Delavan nozzle.
The Delavan 2.50-60-w oil burner nozzle delivers consistent atomization and accurate fuel flow for oil-fired heating systems. It is a trusted replacement nozzle for annual maintenance and combustion tune-up service calls.
