What can be done to correct a dripping nozzle?
Usually, the problem can be easily corrected by raising the front of the appliance with appropriate shims. After trying all of the above, you still could encounter some oil running back to the chassis and dripping onto the floor or vestibule shelf.
Can I put a smaller nozzle in my oil burner?
You can substitute an oil burner nozzle SIZE that’s a bit larger or smaller – that’s the gallons-per-hour number, or for your two examples 0.75 gph is the same on both nozzles. If your original nozzle was 60 degrees and you go to an 80 degree you’re installing a nozzle with a wider, shorter flame pattern.
What does the oil nozzle do?
Oil burner nozzles have the job of spraying heating oil into the combustion chamber in a spray pattern of the right size and shape to properly fit the equipment and to assure a fine spray that in turn assures as complete combustion of the heating oil as possible.
Why does my spray nozzle leak?
A bent coupling loses the watertight seal between the hose and a spigot, nozzle, or sprinkler, causing a leak. Push the exposed end of the hose into the connector of the coupling, and then twist the collar of the coupling clockwise to tighten it.
What is nozzle drip?
The Fuel Nozzle Drip Retainer is said to virtually eliminate the wasted drops of fuel that trickle out of gas pumps. For most of us, it’s simply one of life’s little annoyances those last few drops of fuel that dribble out of the nozzle at the gas station.
Can you clean an oil burner nozzle?
The nozzle itself will need to set for about a half an hour to make sure to get all of the soot and debris off of it. Once you have taken the nozzle out of the kerosene get out your rag and wipe it clean. If there looks to be any debris still hanging on then get a can of compressed air and blow it off.
How often should I change my oil burner nozzle?
Prepare to change your oil burner nozzle annually. However, some units will require more maintenance than others.
Is there a strainer in an oil burner nozzle?
It is common practice to have either a 70 mesh or 200 mesh strainer protect the nozzle. Proper fuel oil atomization and uniform spray pattern are important factors to consistent and efficient boiler operation. In order to maintain the flame pattern and atomization an appropriate level of filtration is required.
Can you clean a oil burner nozzle?
Are B nozzles solid?
Solid-Cone Type B nozzles produce a spray that distributes droplets fairly uniformly throughout the complete pattern. The spray pattern becomes progressively more hollow at higher flow rates, particularly above 8.00 GPH. Provides smooth ignition and efficient combustion, particularly in larger burners.
What should the pressure be on an oil nozzle?
That means the nozzle will spray .75 gallons per hour of fuel oil at 100 psi. Nozzles are generally rated at 100 psi, and that is the pressure that most residential-style oil burners run at, but not all. It also has an 80-degree spray angle.
Where can I find the oil burner nozzle pattern?
Look on the data plate for your heating boiler or furnace oil burner and at the data tag for the oil fired furnace or boiler itself. One of those, often the oil burner, will include the recommended oil burner nozzle size and pattern type. A TOTAL LOOK AT OIL BURNER NOZZLES [PDF] from Delavan, an oil burner nozzle manufaturer.
Why is my oil furnace nozzle not working?
Warping and Shifting. The metal of your oil furnace nozzle can actually warp over time causing the flow of fuel to become inconsistent or even misdirected. Out side of actual material warping from heating and cooling, parts can also shift in some cases over time so they do not line up properly causing the burner not to operate properly.
What causes the oil to swirl in the nozzle?
The nozzle, through the swirl slots, swirl chamber and orifice converts the energy from pressure to velocity. Approximately half of the pressure is converted or dropped across the swirl slots and chamber. At this point, as their name implies, the swirl slots cause the oil to swirl in the swirl chamber.
That means the nozzle will spray .75 gallons per hour of fuel oil at 100 psi. Nozzles are generally rated at 100 psi, and that is the pressure that most residential-style oil burners run at, but not all. It also has an 80-degree spray angle.
Can you substitute the nozzle on an oil burner?
First, if you haven’t done so, see OIL BURNER NOZZLE GUIDE then come back to this page OIL BURNER NOZZLE SUBSTITUTIONS. You can substitute an oil burner nozzle SIZE that’s a bit larger or smaller – that’s the gallons-per-hour number, or for your two examples 0.75 gph is the same on both nozzles.

How does atomizing work in an oil nozzle?
Atomizing is raising the pressure of the fuel and forcing it through the nozzle. Essentially, the fuel comes out of the nozzle vaporized. It is then mixed with air and burned.
