7 Claims. (Cl. 158—56)
rl‘his invention relates to oil burners and the
Figure 8 is a sectional View of the generating
like and is particularly adapted to be used in chamber taken on line 8-8 of Figure 3, looking
furnaces, boilers, cook stoves, in fact, any place
5'
where heat is required.
The primary object of this invention is to in
troduce hydrogen and oxygen in the form of
steam together with the hydrocarbon contained
in the low grade fuels, expanding both within a
’ heated chamber prior to expelling the mixture in
10 the form of gas from the burner jets at which
time additional secondary air is induced by the
flow of the gas from the jets prior to combustion.
Another object of the invention is to provide
a burner having no moving parts, but at the
15 1 same. time completely vaporizing ‘the fuel prior to
combustion.
A further object of the invention is to prevent
carbonization of the fuel within the burner unit
itself.
20
Another object is to permit rapid, easy and
positive starting of the burner when cold.
A further object is to introduce the proper
quantity of steam into the gas mixture by in
jection.
25
A still further object is to water jacket the
fuel nozzle and fuel supply line throughout its
length within the ?re-box, preventing the fuel
supply line and nozzle from carbonizing while
delivering fuel to the generating chamber.
Another object is to provide a hot spot that
30
will be equal in temperature over its entire sur
face.
A still further object is to build the generating
chamber of a low heat conducting material, while
35 .the delivery pipes to the burner jets are of a
rapid heat conducting material.
Referring to the drawing:

and improved oil burner.

l is the generating chamber having a remov
able cap 2 on its one end and tubes 3 and 4
on its opposite end turning downward in the
curved portion 4A having a horizontal section
of tube 5, forming a lower ?ame section, curved
upwardly at 5 and terminating in the horizontal
portion 1 forming an upper ?ame section with a
closed curved end 8. The generating chamber
housing I is made from a material of low heat 15'
conductivity while the tubes 3 and 4 throughout
their entire length, are of high heat conducting
material. The cap 2 has nipples 9 and H! on its
outer end and a bell portion ll extending in~
wardly within the generating chamber I.
Bell I2
- ‘
also is an integral part of the cap 2 and extends 20
in beyond and within the bell H, as best shown
in Figure 3. The hollow tube l3 surrounds the
fuel line I4 and provides a water space I5 for
surrounding the fuel line H clear to the end I6 26
of the nozzle IT. This water jacket is for the
purpose of preventing carbon accumulation at
the end I‘! or the nozzle of the fuel line [4. The
whole assembly is longitudinally adjustable with
in the nipple 9 and the inner bell l2 or is ad
justed to any position by the stufiing box IS. The 80
fuel line It receives its fuel from the control
valve 20 while the water jacket l3 receives a
water supply from the valve 2|.
In order to introduce steam within the generat- 35 -
ing chamber I together with the fuel from the noz
zle ll, a boiler 22 is provided. The boiler 22 con
sists of an outer coil 23 starting with the tube
24 leading from the connection 25 of the water
jacket !3. The opposite lead 26 of the outer coil
23 terminates in an inner or smaller coil 21, coiled
in a downward spiral, terminating in the tube 28
which is packed into the nipple Ill by a suitable
connection or stu?ing box 29. The nipple H)
has a passage 38 terminating‘ in a nozzle 30A for
discharging the steam past the' bell l2 and mix
ing it with the fuel from the nozzle I l. The coils
are supported on a plate 2'!’ carried by rods 28'
depending from the cap 2. A vaporizing trough
or hot spot is shown at 3| extending along the
lower side or bottom of the generating chamber.
This trough is made from a high heat conduct
ing material so that the heat is evenly distributed
over its entire surface. The heat trough 3|
terminates in a cylindrical sleeve 32 which ?ts

snugly within the heat chamber l within the
cap 2. The heat chamber and the cylindrical
portion 32 ?t against the gasket 33 within the
cap 2, the whole assembly being locked in posi
tion by the cap screw 34. The cap screw is
threaded Within the chamber I. The cap 2 has
a slot 3'5 providing adjusting means against the
gasket 33. The heating trough 3! is an important
part of this invention because of its high heat
nozzle, a water jacket surrounding the fuel pipe
to the point of the nozzle, said water jacket and
fuel pipe being longitudinally of the nipple, and a
vaporizing trough having an annular portion sur
rounding the nozzle and nipple and extended lon
gitudinally of the generating chamber as an up
wardly opening section, the vaporizing trough be
ing of high heat conductivity.

end wall of the cap, a fuel pipe terminating in a
To start the burner, a pan 36 having a suitable
wick therein is saturated from the fuel oil which
is supplied down through the pipe 3'! from the fuel
nozzle ll, supplying heat to the generating cham
15 ber. As the heat from the burning fuel in the pan
36 starts the generation of vapor in the generat
ing chamber, a portion of such vapor will flow
through the tube 3'! and be ignited from the ?ame
of the burning fuel in the pan 3B for generating
20 steam in the coils of the burner. The amount of
water admitted into the boiler will be controlled
automatically by the pressure generated within
the chamber l and pipes 3 and 4 leading to the
burner jets indicated at 40. The main object of
this invention is the mixing of the steam from the
nozzle 38A with the fuel from the nozzle ll after
which this mixture is delivered to the burner
jets 46.
Referring to Figure 4, part of the burner jets
soI are directed against the generating chamber. An

ber, a cap closing one end thereof, a nipple car
ried by the cap, a fuel pipe movable longitudinally
of the nipple and terminating in a nozzle, a steam
inlet passage formed in the cap at one side of the
nozzle, a steam generating coil supported by the
cap and communicating with the steam inlet,
means for admitting water to the coil, and a con
nection from the generating chamber to and be
neath the coil, said connection terminating as a
20
burner to generate steam in the coil.
4. An oil burner including a generating cham
ber, a cap for one end thereof, a nipple carried by
the cap, a steam inlet formed in the cap, a fuel
pipe terminating in a nozzle, a water jacket for
the fuel pipe, a coil carried by the cap and sub 25
j ect to heat from a burner fed from the generating
chamber, a communication between the coil and
steam inlet, and a communication between the coil
and the water jacket about the fuel pipe.
5. An oil burner including a generating cham
ber, a cap for one end thereof, a nipple carried by
the cap, a steam inlet formed in the cap, a fuel
resting on top of the generator, provides a means
of controlling the amount of heat applied to the . pipe terminating in a nozzle, a water jacket for
generator. The revolving of the same to the the fuel pipe, a coil carried by the cap and subject 35
right, referring to Figure 4, upon the top of the to heat from a burner fed from the generating
generator traps the ?ames 42 within the space 43
directing a greater amount of heat against the
generator I. By revolving the angle to the left it
will allow the flames to escape past the generator
more easily thereby applying less heat. In other
“words, the angle iron 4! resting longitudinal upon
the top surface of the generator provides a con
trel for the amount of heat to be absorbed by the
generating chamber. The ?ames 44 are directed
a past one side of the heat chamber, while the flames
45 are directed upward.
The ?ames 42 and 44
may be directed towards the left or reversed as
shown in Figure 4, their direction depending upon
the type of ?re box that the burner is installed in.
60, Having thus described my invention, I do not
wish to be limited to the particular form of con
struction as my invention is adaptable; to other
mechanical embodiments still coming within the
scope of the claims to follow.
