Delavan Oil burner nozzle 01000-80B7

The Delavan oil burner nozzle 01000-80B7 is a component designed for use in oil burners, where it atomizes fuel into fine droplets for efficient combustion. It has a capacity of 10 gallons per hour (GPH) and a spray angle of 80 degrees. The nozzle features a B solid-cone spray pattern, which distributes droplets uniformly across the pattern, becoming more hollow at higher flow rates above 8 GPH. This design promotes smooth ignition and efficient combustion, particularly in larger burners. The nozzle is identified by SKU 01000-80B7 and article number 345.892.283.

When selecting a replacement oil nozzle of this type, ensure the capacity (GPH), spray angle, and spray pattern (e.g., solid-cone B) match the burner's requirements. Nozzles are typically threaded and must be installed with the correct size and sealing method. Before ordering, verify the nozzle's flow rate and angle against the burner's specifications, and check the physical dimensions to ensure compatibility with the existing assembly.

Oil nozzles can fail due to clogging, wear, or damage, leading to poor atomization and incomplete combustion. Symptoms include soot buildup, reduced heating efficiency, uneven flame, or burner shutdown. If these issues occur, inspect the nozzle for blockages or erosion and replace it if necessary.
