A flame retention head assembly for use in the air tube of a fuel burner having a fuel nozzle and ignition means for igniting the burner. The head assembly comprises a cylindrical ring positioned coaxially in the air tube and secured to the fuel nozzle.
What is a flame retention burner head?

What is the function of the retention head on a torch?
Retention Head Elements. The first is to enclose the flame in an envelope of air, thus helping to contain stray oil droplets and allow them to be burned. Some heads incorporate the use of a sleeve on the end of the tube which helps to turn the air into the flame. The second function, and probably the most important,...
How does a flame retention baffle work?
The flame retention baffle is arranged transversely of the air stream, occupying a substantially annular sec tion coaxially of the burner tube just beyond the atomizing nozzle. A central aperture in the baffle admits andaccommodates the spray discharge cone from the nozzle.
How does the retention head keep the flame close to the end of the burner?
How does the retention head keep the flame close to the end of the burner? An eddy current creates a lower air pressure in front of the nozzle. Why are forced draft oil burners necessary?
What is a combustion head?
The combustion head (also referred to as the turbulator, fire ring, retention ring or end cone) creates a specific pattern of air at the end of the air tube. The air is directed in such a way as to force oxygen into the oil spray so the oil can burn.
What is the head in burner?
The burner head itself is just a hollow metal disk with holes or slots in the outside edge. Many burners are designed with a metal or ceramic cap that sits atop the burner head and diffuses or directs the flames emerging from the burner head.
What does a good oil burner flame look like?
A flame that is dark yellow indicates less air. A flame that is receiving the right mixture of air should have a white, chrome or blue color. Depending on the brand of oil burner, the flame could also appear light yellow.
How many types of cylinder heads are there?
three typesThe cylinder head may be classified depending upon the layout of valves and ports. There are mainly three types – Loop-flow type, offset cross-flow type or in-line cross-flow type. In the loop-flow design, the inlet & exhaust manifolds are on the same side which helps pre-heating of the intake air.
What are the 3 types of combustion chamber?
There are three main types of combustion chamber in use for gas turbine engines. These are the multiple chamber, the tubo-annular chamber, and the annular chamber.

Why is my oil burner putting out black smoke?
If the smoke is black, the furnace is not burning the oil completely and fuel is being wasted. Oil-fired burners are used in many parts of the country as the basic heat source for warm air and hot water heating systems. Most of the home oil systems in use today are called pressure burners.
What color should an oil burner flame be?
The flame color changes from red to yellow when it doesn't get enough oxygen, as occurs with a candle flame. A blue flame signifies a properly-functioning oil or gas furnace; any other color indicates a problem with the furnace.
What causes orange flame in furnace?
If you have a yellow, orange, or red burner flame, this usually means that your burner is not receiving enough air for complete combustion. Besides wasted gas, higher energy bills, and more soot, the main danger of improper combustion is the increased amount of carbon monoxide (CO) produced by the combustion process.
What is the purpose of a cylinder head?
They're key to controlling air flow in and out of the cylinders and fuel deployment. The cylinder head also holds the injectors and valves – and contains more moving parts than any other part of the engine. Although largely unnoticed, the cylinder head plays a key role in your engine.
What is a head in an engine?
The upper part of the engine is called the cylinder head, while the lower part is the engine block. The cylinder head sits on the engine and closes off the combustion chamber. The gap that remains between the cylinder head and the engine is completed by the head gasket.
Is a cylinder head the same as a head gasket?
At the top of the engine is the cylinder head where the valves open and close to let the air-fuel mixture in and out of the combustion chamber. The head gasket ensures the compression generated by the ignition of the air-fuel mixture remains inside the combustion chamber.

What is the difference between a combustion head and a non-flame retention head?
These heads differ from the non-flame retention heads in that the flame is held very close to the face of the head. The flame is smaller and more compact and usually is 300° to 500°F hotter than with non-flame retention heads.
What is a non retention head?
Non-Retention Head. Historically, the first combustion heads used were referred to as non-flame retention heads. The base of the flame is usually a good distance off the surface of the head and thus not “retained” or locked onto the head. These heads are typically very simple in construction, usually consisting of a large hole in the end ...
What is combustion head?
The combustion head (also referred to as the turbulator, fire ring, retention ring or end cone) creates a specific pattern of air at the end of the air tube. The air is directed in such a way as to force oxygen into the oil spray so the oil can burn. The combustion head is one link in the chain necessary to burn the oil efficiently.
What are the primary slots on a combustion engine?
The primary slots are the slots that radiate out from the center opening towards the outside of the head. The secondary opening is a slot which is concentric to the center opening and follows the circumference of the combustion head. All three openings affect the way air is delivered to the oil spray.
How can the width of a one piece head be varied?
The width can be varied through the use of a variety of one piece heads with a fixed secondary slot according to the firing rate for which it was designed . Or, the head must be able to move against or away from a ring thus closing or opening the secondary slot according to the firing rate requirements.
Why does a flame head have a spinner?
This head produces a loose long flame because the velocity of the air passing through the head is so low due to the large opening in the head.
What is the role of the slot width in combustion?
The primary slots are where the most important mixing of oil and air occur. The slot width regulates the amount and the velocity of the air passing through the slot.
What size head for SF burner?
The standard 5/16” dimension can be used on all Series AF, AFG, SR, SM and SF burners using the “F” style head and will remain the standard setting for our L1, V1 and FBX airtube combinations.
What nozzles do Steamhead recommend?
Steamhead - Wayne recommends Delavan 80° A hollow nozzles, and that is what I bought. The previous servicemen were using 70 and 60 degree nozzles to try to keep the flame off of the failing sides (where the burn marks show).
Where is Teflon tape on a spin on oil filter?
The only place that has teflon tape is the 2 flare fittings on the spin-on oil filter adapter. Those now never get worked - only the flare connections if necessary.
