the oil must first be vaporized— converted to a
vapor or gas—before combustion can take
place. This is usually accomplished by the
application of heat. The oil vapor must be
mixed with air in order to have oxygen present
for combustion. The temperature of this
mixture must be increased above the ignition
point. A continuous supply of air and fuel must
be provided for continuous combustion.

6. 6
The simplest way to burn fuel oil is the old
vaporizing pot type burner in which heat is
applied to a puddle of oil, thus vaporizing the
fuel. These vapors are then burned after mixing
with the proper amount of air. In most
applications, this method of vaporizing is too
slow for high rates of combustion and cannot
be controlled in the low rates,

7. 7
What the Nozzle Does:-
1. Atomizing
it speeds up the vaporization process by breaking up the oil into tiny
droplets. Individual droplet sizes range from .0002 inch to .010 inch.
The smaller droplets are necessary for fast quiet ignition. The larger
droplets take longer to burn and help fill the combustion chamber.
2. Metering
A nozzle is so designed and dimensioned that it will deliver a fixed
amount of atomized fuel to the combustion chamber…within
approximately plus or minus 5% of rated capacity. 5GPH nozzle will
not pass 10 GPH flow.
3. Patterning
A nozzle is also expected to deliver the atomized fuel to the
combustion chamber in a uniform spray pattern and spray angle best
suited to the requirements of a specific burner. More details on
patterns and angles later

23. 23
Where must
the oil nozzle
be
located?

24. 24
where the nozzle will produce the best
combustion results.

25. 25
A nozzle placed too far forward causes too
great an air velocity around the nozzle and
ignition often becomes more like an explosion.
If a flame is formed at all it will be very erratic
and dispersed Oil

26. 26
Oil sprayed from a nozzle placed too far back
will be caught by the combustion head and may
result in oil flooding from the burner tube
