What do the numbers mean on an oil furnace nozzle?

What do the numbers mean on an oil furnace nozzle?

Oil burner nozzles are present in most forced combustion air burners. The numbers on the nozzle tell us the specific rating of the nozzle, the spray pattern angle, and the spray pattern type. That means the nozzle will spray .

What’s the difference between H and EH nozzles?

The H nozzles are 15% tolerance, the EH are selected to be 5% tolerance, so changing a nozzle may require some adjustment in the case of EH, and almost certainly in the case of H. You won’t know the nozzle is good until you have tested it, so you need test equipment too if you want it to be clean AND efficient.

How do I choose an oil burner nozzle?

Multiply the oil burner nozzle size (firing rate in gallons per hour) x 138,200 (Btus per gallon of No. 2 heating oil) x an efficiency estimate (use . 75 for older furnaces and . 80 for newer furnaces if you don’t have a recent efficiency measurement).

Are B nozzles solid?

Solid core spray pattern type B nozzles are more-often used in larger oil burners.

How do you read an oil burner nozzle?

Color Codes for Oil Burner Nozzle Caps or Vials

1. Blue = B – Solid cone spray pattern.
2. Green = W = All Purpose.
3. Red = A = Hollow cone spray pattern.

What is es nozzle?

The “ES” nozzle distributes atomised oil droplets evenly. throughout the spray pattern in low firing rate applications. For those applications specifying an “ES” type solid spray pattern, this nozzle will provide optimum combustion efficiency.

What is burner nozzle?

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.

How long do oil burners last?

Theoretically, the lifespan of an oil furnace is around 25 years. This estimate depends on a number of factors, in particular the amount of regular and preventive maintenance that was done on the equipment over the years. A well-maintained oil furnace has a much longer lifespan than one that was neglected.

How much oil do you put in an oil burner?

All you need is a little water in the bowl of the oil burner or container of your electric oil diffuser (maybe half to two thirds full) and a few drops of essential oil (3-5 drops for a small bowl/container, 5-8 drops for a medium sized one and 7-10 drops for a large one).

What is the difference between a hollow core and a solid core oil nozzle?

Hollow cone nozzles generally have more stable spray angles and patterns under adverse conditions than solid cone nozzles of the same flow rate. This is an important advantage in fractional gallonage nozzles where high viscosity fuel may cause a reduction in spray angle and an increase in droplet size.
