Description

The Monarch Oil nozzle 0986717 is a replacement oil burner nozzle with a capacity of 2 gallons per hour and a spray angle of 60 degrees. It features a hollow cone (HO) spray pattern and is designed for use with oil having an operating viscosity of 70 ssu (approximately 13 centistokes). This nozzle atomizes fuel into fine droplets for efficient combustion in boilers and furnaces.

Nozzle Type

Choosing and fitting

When selecting a replacement oil nozzle of this type, verify the capacity (GPH), spray angle, and spray pattern (e.g., solid, hollow, or semi-solid) to match the burner's requirements. The nozzle must be compatible with the fuel viscosity and operating pressure range specified by the equipment. Installation involves removing the old nozzle, cleaning the adapter, and torquing the new nozzle to the manufacturer's specification without over-tightening.

Signs of failure

Common failure modes for oil nozzles include clogging from debris or carbon buildup, which causes poor atomization, uneven flame, or soot formation. A worn or damaged nozzle may result in incomplete combustion, increased fuel consumption, or burner pulsation. Check the nozzle for blockages, erosion, or distortion, and replace it if the spray pattern is irregular or the burner fails to ignite properly.
