Delavan Oil burner nozzles PA110-70R1

The Delavan PA110-70R1 is an oil burner nozzle designed to spray fuel oil before it enters the burner or combustion chamber, ensuring efficient mixing with air for optimal combustion. It has a capacity of 1.1 gallons per hour (1.1 kg/h) and a spray angle of 70 degrees. The spray pattern is AR, which is a solid cone type with a slightly lower concentration of droplets in the center, suitable for low to medium capacity burners up to 2.00 GPH. This nozzle is used in various technical devices, including heating boilers and other fuel oil applications. Its article numbers are 345.892.297 and SKU PA110-70R1.

When selecting a replacement oil burner nozzle of this type, ensure the capacity (in GPH or kg/h), spray angle, and spray pattern match the original specifications. The nozzle must be compatible with the burner's flow rate and combustion chamber design. Installation involves removing the old nozzle, cleaning the mounting threads, and tightening the new nozzle to the recommended torque without over-tightening. Always verify the nozzle's dimensions and thread type before ordering.

Common failure modes for oil burner nozzles include clogging due to dirt or debris, which can cause uneven spray, poor combustion, or soot buildup. A worn or damaged nozzle may lead to incomplete fuel atomization, resulting in increased fuel consumption, smoke, or a noisy flame. If the burner fails to ignite or produces a weak flame, inspect the nozzle for blockages or wear and replace it if necessary.
