Description

The Delavan Oil Nozzle 00950-80B7 is a component designed for use in oil burners, with a capacity of 9.5 gallons per hour and a spray angle of 80 degrees. It features a B solid-cone spray pattern, which distributes fuel droplets uniformly across the spray pattern, becoming progressively more hollow at higher flow rates, particularly above 8.00 GPH. This nozzle type provides smooth ignition and efficient combustion, especially in larger burners. Its primary function is to atomize fuel into fine droplets for optimal mixing with air, ensuring complete combustion and precise fuel output control.

Choosing and fitting

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 burner's requirements. The nozzle must be compatible with the burner's fuel pump pressure and the desired firing rate. Installation involves removing the old nozzle, cleaning the mounting threads, and torquing the new nozzle to the manufacturer's specified value, typically 15-20 ft-lb, without over-tightening. Always verify the nozzle's specifications against the burner's manual before ordering.

Signs of failure

Common failure modes for oil nozzles include clogging due to dirt or debris in the fuel, which can cause incomplete combustion, soot formation, or a pulsating flame. A worn or damaged nozzle may result in an improper spray pattern, leading to poor ignition, increased fuel consumption, or excessive smoke. If the burner fails to ignite or produces a yellow, flickering flame, inspect the nozzle for blockages or wear and replace it if necessary.
