Delavan Oil burner nozzles 00250-60B7

The Delavan 00250-60B7 is an oil burner nozzle with a capacity of 2.5 gallons per hour and a spray angle of 60 degrees. It features a B solid-cone spray pattern, which distributes fuel uniformly throughout the complete pattern. This nozzle is designed for optimal fuel atomization, ensuring efficient combustion and reducing emissions of harmful substances. It provides smooth ignition and efficient combustion, particularly in larger burners. The article numbers for this item are 00250-60B7, 3042140, and 345.892.109.

When selecting a replacement oil nozzle of this type, ensure that the capacity (in gallons per hour), spray angle, and spray pattern (solid-cone, hollow-cone, etc.) match the burner's requirements. The nozzle must be compatible with the burner's fuel pump pressure and flow rate. Installation involves removing the old nozzle and installing the new one with the correct torque, ensuring a proper seal. Always verify the nozzle's specifications against the burner's manual before ordering.

Common failure modes for oil nozzles include clogging due to dirt or debris, which can cause uneven spray patterns, poor combustion, and increased soot production. A worn or damaged nozzle may lead to ignition problems, such as hard starting or flame instability. If the burner exhibits these symptoms, inspect the nozzle for blockages or wear and replace it if necessary.
