Delavan Oil nozzles 01900-60B0

The Delavan 01900-60B0 is an oil nozzle designed for use in larger burners, with a capacity of 19 gallons per hour and a spray angle of 60 degrees. It features a B solid-cone spray pattern, which distributes fuel uniformly throughout the pattern, ensuring smooth ignition and efficient combustion. This nozzle is suitable for applications requiring a high fuel flow rate and is identified by the article number 345.892.247.

When selecting a replacement oil nozzle of this type, ensure that the capacity (in gallons per hour), spray angle, and spray pattern (e.g., solid-cone) match the original specifications. The nozzle must be compatible with the burner's fuel pump pressure and the combustion chamber design. Installation involves removing the old nozzle, cleaning the adapter, and torquing the new nozzle to the manufacturer's recommended specification, typically 15-20 ft-lb, without over-tightening.

Common failure modes for oil nozzles include clogging due to dirt or debris, which can cause uneven flame, soot formation, or incomplete combustion. A worn or damaged nozzle may result in a distorted spray pattern, leading to poor ignition, flame instability, or increased fuel consumption. Regular inspection and cleaning of the nozzle and its filter are recommended to prevent these issues.
