Delavan 2.50-60-b Type B Solid Cone Oil Burner Nozzle 2.50 Gph 60 Degree

Product Description

The Delavan 2.50-60-b is a Type B Solid 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 systems, including forced air furnaces, boilers, and water heaters. It plays a critical role in the combustion process by atomizing fuel oil into a fine, consistent mist that mixes with air for efficient, clean burning. The solid cone spray pattern delivers fuel evenly across the entire cone shape, making it well suited for burner heads that require complete flame coverage from the center outward. HVAC technicians and heating system service professionals rely on this type of nozzle when performing annual tune-ups, combustion efficiency testing, or replacing worn or clogged nozzles. Oil burner nozzles should be replaced at least once per heating season to maintain peak efficiency and reduce soot buildup. The 2.50 GPH flow rate indicates the volume of fuel oil delivered per hour at a standard operating pressure of 100 PSI. The 60-degree angle controls the width of the spray cone, which must match the combustion chamber geometry to ensure proper heat distribution and complete fuel combustion. Using the correct nozzle type, flow rate, and angle is essential for achieving the right air-to-fuel ratio and minimizing carbon deposits. The Type B designation refers to the internal filter and metering disc design used by Delavan, which affects flow consistency and atomization quality. Delavan is a well-established manufacturer of precision oil burner nozzles trusted by heating contractors across North America. This nozzle is compatible with standard Beckett, Carlin, Riello, and Wayne oil burner assemblies that accept industry-standard nozzle fittings.
