Delavan 0.70-60-b Type B Solid Cone Burner Nozzle 0.7 Gph 60 Degree Blue Vial

Product Description

The Delavan 0.70-60-b is a Type B Solid Cone Burner Nozzle designed for oil-fired heating systems used in residential and commercial applications. It delivers a flow rate of 0.7 gallons per hour at a 60-degree spray angle, producing a solid cone spray pattern. This nozzle is identified by a blue vial, which makes it easy to sort and install in the field. HVAC technicians and oil burner service professionals rely on burner nozzles like this one to atomize fuel oil into a fine mist that mixes with air and ignites cleanly inside the combustion chamber. Proper atomization is critical for efficient combustion, low soot buildup, and reduced emissions. The solid cone pattern distributes fuel evenly across the full width of the spray, making it well suited for specific burner head configurations that require full coverage rather than a hollow spray ring. Inside the nozzle, a circular exit orifice is preceded by a swirl chamber with a multi-slotted in-line distributor and a central line. This internal geometry accelerates and spins the fuel before it exits the orifice, breaking it into uniformly sized droplets. Consistent droplet size means more predictable combustion performance, which translates to stable flame shape, reliable ignition, and better fuel efficiency. The 60-degree spray angle is a common specification for many residential oil furnaces and boilers. When replacing a worn or clogged nozzle, matching the original flow rate, spray angle, and spray pattern type is essential for maintaining proper burner operation. The 0.70-60-b is a direct replacement nozzle for systems calling for a 0.70 GPH, 60-degree, Type B solid cone specification. Always verify the burner manufacturer requirements before installation.

• Type B Solid Cone spray pattern for full-coverage fuel atomization in compatible oil burner systems
• 0.7 GPH flow rate at 60-degree spray angle for precise combustion performance in residential and light commercial furnaces and boilers
• Blue vial color coding for fast field identification and accurate nozzle selection during service calls
