Delavan Oil nozzles 00135-90A1

The Delavan Oil nozzle 00135-90A1 is a component designed for fuel dispersion in combustion systems. It has a capacity of 1.35 gallons per hour and a spray angle of 90 degrees. The nozzle features a hollow-cone spray pattern and is classified as type A. It is suitable for use with liquid or gaseous fuels in heating systems, industrial furnaces, and boilers. Its combustion characteristics include good ignition and low-noise combustion.

When selecting a replacement oil nozzle of this type, ensure that the capacity, spray angle, and spray pattern match the burner's requirements. The nozzle type (e.g., A) must correspond to the burner's air pattern and throughput. Check the nozzle's thread size and dimensions to confirm compatibility with the existing assembly. Installation typically involves removing the old nozzle and fitting the new one securely, ensuring proper alignment and torque.

Common failures of oil nozzles include blockage from sediment, wear of internal parts, leaks, and fuel supply disruptions. Symptoms may include uneven flame, poor combustion, increased emissions, or difficulty igniting. Regular inspection and cleaning can help identify issues early, and replacement is necessary when performance degrades.
