What are the numbers on oil burner nozzles?
On oil nozzles, the first number is gallons of oil per hour at 100psi. The second number is the apex angle (30° to 90° arc) of the oil spray cone. The letters designate the fill of the spray cone: A or H = hollow, B or ES = solid, SS = semi-solid, W = multipurpose.
What is the difference between an A and B furnace nozzle?
The difference between an A nozzle and a B oil burner nozzle is that the B produces a solid rather than hollow core spray pattern. B nozzles are more-often used on larger or industrial oil burners. In my opinion an A nozzle will give an easier-to-set and cleaner flame in a small oil burner.
How do I choose an oil burner nozzle?
the spray angle in gas oil nozzles is determined according to the length of the boiler. meaning, if the length of the boiler or combustion chamber is high or the number of cast iron boilers blades is more than 10, then the 45 degrees nozzles and if the boiler is short, 60 or 80 degrees nozzles are used.
How many Btus is a .85 oil nozzle?
85 X 60A nozzle (1.05 gph)for a rating of 123,000 btu's. However, it came with a .
What are the three types of nozzles?
Spray nozzlesFlat fan nozzles. Flat fan nozzles produce a line of spray. ... Hollow cone nozzles. Hollow cone nozzles produce a ring of spray. ... Full cone nozzles. Full cone nozzles produce a solid circle of spray. ... Tank cleaning. ... Air atomising nozzles.
What are the 2 types of nozzles?
The two most popular types for chemical applica- tions are the flat spray and hollow cone nozzles.
What do nozzle numbers mean?
Most companies identify their flat-fan nozzles with a four or five digit number (Figure 2). The first numbers are the spray angle and the other numbers signify the discharge rate at rated pressure. For example, an 8005 has an 80 degree spray angle and will apply 0.5 gallons per minute (GPM) at rated pressure of 40 psi.
What do the nozzle sizes represent?
The orifice size of the nozzle determines the operating pressure of your machine. As a rule of thumb, the smaller the orifice, the greater the restriction of water flowing through the machine. This causes the pressure to increase. Choosing a nozzle with too large of an orifice will reduce operating pressure.
How do I choose the right nozzle?
You'll want to determine the nozzle flow rate at gallons per minute (gpm). To find that, start with your application rate in gallons per acre (gpa). Next, find an efficient and safe ground speed in miles per hour (mph). Then, determine the spray width per nozzle (W).
How long does 100 gallons of oil heat last?
about six daysHow long should 100 gallons of heating oil last? Using the calculation above, 1.7 gallons per hour x 10 hours a day (assuming the number of hours you spend at home is 10 hours) = 17 gallons a day. That means, 100 gallons of oil will last you about six days (100-gallon tank / 17 gallons per day = 5.8 days).
Are gas nozzles different sizes?
Diesel nozzles are bigger than gas fuel pump nozzles. Therefore, if you attempt to put a diesel nozzle in a gas fuel tank, it will not fit. Also, it would be best if you never attempted to do this, as adding diesel to a gas vehicle can harm the vehicle.
Can I clean a furnace nozzle?
Use an air compressor or canister of compressed air to spray pressurized air into the nozzle and filter. The pressurized air will help dislodge any loose debris left in the nozzle or filter.
What is B terminal on furnace?
W/B: The W/B terminal controls the heat relay or valve. When the thermostat calls for heat, a signal is sent to power up the furnace and the blower fan or the boiler, heating your home.
What do the letters mean on an oil burner nozzle?
Patterns are designated as solid (B), hollow (A), and semi-solid (W). A solid nozzle indicates the vaporized oil is distributed evenly throughout the entire spray pattern. A hollow nozzle distributes more of the oil to the outer ring of the pattern, and a semi-solid is neither.
What is a Type A oil nozzle?
Hollow cone nozzles (Type A) can be used in burners with a hollow air pattern as well as in small burners (those firing @ 1.0 gph and under), regardless of air pattern. Type A nozzles produce a spray which delivers fine droplets outside the periphery of the main spray cone.
What are the different types of fuel nozzle?
Fuel nozzle types There are two types of fuel nozzles on PT6 engines — simplex and duplex.
What are the different types of oil burner nozzles?
Another common oil burner nozzle pattern is the Type W nozzle that is "in between" a hollow-cone and a solid-cone spray pattern. Type W nozzles are sometimes substituted for an A or B spray pattern nozzle. The duplication in codes accommodates not only a range of oil burner nozzle manufacturers or OEM specifications, but also some special features.
How do I choose the right oil nozzles?
When replacing oil nozzles, first and foremost use oil nozzles with the same shape of head.
What do the numbers on an oil burner nozzle mean?
When the service company buys oil burner nozzles (in huge quantities in their case) each oil burner nozzle comes in a (usually color-coded) plastic container such as the one we show at left, indicating the gph rating and the nozzle angle and spray pattern.
What is a type W nozzle?
Type W nozzles are sometimes substituted for an A or B spray pattern nozzle. The duplication in codes accommodates not only a range of oil burner nozzle manufacturers or OEM specifications, but also some special features.
Flat Fan Sprayer Nozzle Part Numbers: Example and Explanation
Sometimes the sprayer tip part numbers are clearly listed on the nozzle, and sometimes they are harder to see. The numbers may be on the side of the nozzle or the very tip near the nozzle opening.
How do I know what Spray Nozzle Size I need?
Every nozzle type will have a chart that the manufacturer provides. The nozzle charts will show the different outputs for each spray nozzle at different PSI as well as the droplet size that is produced at that PSI.
How to Read a Spray Nozzle Chart
Below is a sprayer nozzle chart from TeeJet. It shows the capacity and droplet sizes produced at a certain pressure for the “Turbo TeeJet” nozzle type. You can see in the far left column the sprayer tip number. Notice the numbers are the same except for the last couple of digits.
Non-Flat Fan Sprayer Numbers
When it comes to most other types of sprayer nozzles, spot sprayer nozzles, boomless nozzles, etc., there is not a universal numbering system. However, the numbers will still provide us with some information about nozzle type and capacity.
Why The Numbers On Your Spray Nozzle Matter
Sprayer nozzles are made to perform a specific way. If you don’t have the right nozzle your entire sprayer can be rendered ineffective. Knowing what the numbers on your sprayer nozzle mean will help you identify the right nozzles for your spraying task.
What type of nozzle is used for oil burners?
Another common oil burner nozzle pattern is the Type W nozzle that is "in between" a hollow-cone and a solid-cone spray pattern. Type W nozzles are sometimes substituted for an A or B spray pattern nozzle.
What is the job of oil burner nozzles?
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.
What is the spray angle of a nozzle?
For example the nozzle may be stamped 80°. That defines an 80° spray angle (80 degrees).
Why is my oil burner sooting?
If the burner is sooting abnormally AND has a nozzle that's within the range permitted by the manufacturer for your oil burner, the tech will look for any of quite few other causes of oil burner sooting like air leaks, dirty oil, wrong pressure, poor combustion air, wrong draft settings, bad electrodes.
Why is my oil burner grubby?
Like Mikes oil burner nozzle shown in the photograph, oil burner nozzles get grubby during use, especially if the fuel is contaminated or if the oil burner and its electrodes are not properly adjusted.
What does 80°A mean in spray?
Each spray pattern is designated by a letter stamped into the nozzle on one of its facets. So the nozzle whose data we showed above, a Delavan 80°A means the nozzle sprays at an 80 degree angle with spray pattern "A" which we know is hollow.
How many different spray patterns are there?
There are at least nineteen different spray patterns possible. The basics are hollow vs. solid spray patterns (hollow means the core of the spray contains fewer droplets), and various combinations of these parameters. Above: a typical Type A oil burner nozzle, hollow-core spray pattern. [Click to enlarge any image]
What is the pressure of a nozzle?
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. That is the angle at which the spray comes out of the nozzle. The smaller the angle, the narrower the spray pattern. Think of a garden hose with a spray nozzle.
What is an oil burner nozzle?
Oil burner nozzles are present in most forced combustion air burners. They are used with an oil pump to atomize fuel oil and allow it to burn. Atomizing is raising the pressure of the fuel and forcing it through the nozzle. Essentially, the fuel comes out of the nozzle vaporized.
What is a solid nozzle?
A solid nozzle indicates the vaporized oil is distributed evenly throughout the entire spray pattern. A hollow nozzle distributes more of the oil to the outer ring of the pattern, and a semi-solid is neither. W nozzles are typically considered a replacement for both A and B nozzles, although that is not the best option.
How many BTUs in a 1 GPM nozzle?
One gallon of #2 fuel oil contains approximately 140,000 (give or take a 1000 or 2). So, a 1-GPM nozzle @ 100 psi is a 140,000 B TU burner input. If the burner efficiency is 80%, 20% of the fuel energy goes up the flue as unused energy. So, a 1-GPM nozzle on an 80 % efficient burner is equal to around 112,000 BTUs available from the fuel. But what if you need a 1-GPM nozzle, but you only have a .75-GPM nozzle available? Well, increasing the pump pressure above 100 psi can allow for the same amount of fuel input with a smaller nozzle.
Why do we need nozzles?
Nozzles are also used to meter the amount of fuel being used and to vaporize the fuel in an efficient pattern suited to the burner chamber of whatever equipment it is installed on. If you work on burners, you have probably seen and changed out your fair share, as periodic nozzle replacement is necessary for clean and reliable burner operation.
What happens when you squeeze the handle of a sprayer?
If you squeeze the handle only a little, the spray comes out at a wider angle. That would be similar to a higher-degree spray angle. As you squeeze the handle more, the outer edges of the water get closer together. A closer spray pattern would be a smaller angle.
Can you replace a B nozzle with a W nozzle?
W nozzles are typically considered a replacement for both A and B nozzles, although that is not the best option. I prefer to replace nozzles with the type and pattern specified by the manufacturer, but late nights and on-call situations do not always allow it.
What temperature does a fuel nozzle work at?
The fuel may be 40-50°F, the nozzle may operate at temperatures up to 250°F and the off cycle soak temperature may climb to nearly 300°F in some appliances.
Why is it so difficult to generalize about nozzles?
Due to the lack of standards to define the qualities that we give a nozzle, it is difficult to even generalize about their use and application. In the laboratory many of the tests performed are conducted to select the proper nozzle.
What happens if a nozzle gets dirt in it?
If the orifice gets dirt in it or becomes scratched, it will not function properly. Inspect the nozzle adapter before installing the nozzle. If there are deep grooves cut into it from previous nozzles, replace it. Those grooves or a scratched surface are a potential source for a leak.
How does the swirl chamber work?
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.
Is a nozzle exactly the same?
Not all nozzles are exactly alike. There are variations from one manufacturer to another. Conversion charts are good guides, but they do not always take into account the variances.
How to find the right oil burner nozzle?
Here's how to figure the right nozzle: 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. Details about oil burner nozzles are.
What is the nozzle pattern on an oil burner?
The oil burner typically wears a sticker giving the manufacturer's recommended nozzle pattern, angle, and gph rating for a specific fuel unit pressure setting. It's common to vary a few decimal points up or down in gph around that or sometimes to up the pressure and drop the gph to avoid over-firing the burner.
What does the black muck above the threads on the oil burner mean?
Watch out: that black muck just above the threads in your photo suggest that this nozzle may have been leaking and that a new nozzle adapter might be needed to get proper oil burner operation.
What angle should an oil burner nozzle be?
Generally you use a more narrow angle of say 30 to 60 degrees for a long narrow combustion chamber, and you use a wider angle oil burner nozzle, say 70 to 90 degrees for a round or short wide combustion chamber.
What happens if you put a wide angle spray pattern into a narrow combustion chamber?
If you put a wide-angle spray pattern into a narrow combustion chamber then the oil spray impinges too much on the sides of the chamber, you get incomplete combustion, sooty flame, poor burner operation, and possibly a loss of heat when the nozzle clogs up from soot.
What is the difference between an A and B oil burner nozzle?
Luke Thanks for asking: The difference between an A nozzle and a B oil burner nozzle is that the B produces a solid rather than hollow core spray pattern. B nozzles are more-often used on larger or industrial oil burners.
How much air intake does an oil fired boiler need?
If you mean that the door to the boiler room (or furnace room) has to be open for an oil burner to work, that suggests it's air starved - we need about 1 sq. in. of air intake into a small utility room per 1000 BTUH for oil fired heating equipment - so a 90,000 BTUH oil heater would need 90 sq. in. of unfettered air intake opening. If you add louvers and screening the sq. in. requirement is increased.
What type of nozzle is used for oil burners?
Another common oil burner nozzle pattern is the Type W nozzle that is "in between" a hollow-cone and a solid-cone spray pattern. Type W nozzles are sometimes substituted for an A or B spray pattern nozzle.
