Delavan Oil burner nozzles 00400-60B7

The Delavan 00400-60B7 is an oil burner nozzle designed to spray fuel into a fine mist for efficient combustion. It has a capacity of 4 gallons per hour (GPH) and a spray angle of 60 degrees, with a spray pattern type B. This nozzle is used in oil burners to facilitate effective ignition and combustion, reduce emissions, and maximize overall burner performance. It is available in various sizes and spray angles to suit different burner requirements.

When selecting a replacement oil nozzle, ensure the capacity (GPH), spray angle, and spray pattern match the burner's specifications. The nozzle must be compatible with the burner's fuel type and pressure. Installation involves removing the old nozzle and installing the new one with proper torque, ensuring no debris enters the fuel line.

Common failure modes include clogging due to dirt or carbon buildup, which can cause uneven flame, soot formation, or difficulty igniting. A worn or damaged nozzle may lead to poor combustion, increased fuel consumption, or burner shutdown. Regular inspection and replacement are recommended to maintain optimal performance.
