Improvements in and connected with Burners for Use with Liquid
or Gaseous Fuel.
We, BLAND GARDNER SINCLAIR and WALTER SETH WOODWARD, both of 19, Eldon
Street, Finsbury, in the County of London, Engineers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to burners for use with liquid or gaseous fuel and has
for its chief object to provide an atmospheric gas burner which is specially adapted
for burning oil or spirit vapour for heating purposes generally and which can
be very conveniently regulated to burn more or less oil or spirit in accordance
with the amount of heat required.
For this purpose we
provide a vapour chamber with which one end of a
vapourizing coil communicates the other end of such coil being in connection with
the tank or other vessel containing the supply of oil spirit or other liquid fuel
employed. Extending from said chamber is a series of conduits terminating in
nozzles each of which enters a tube formed with perforations and constituting the
burners proper. Adjacent to the said nozzles where they enter the said burner-
tubes are openings through which external air is induced to flow into the said
tubes by the jets of oil-vapour passing from the nozzles thereby causing a mixture
of the air and vapour to take place in the tubes before ignition is effected at the
perforations in the said tubes. The aforesaid vapourizing coil is so arranged with
respect to one of the said burner-tubes that it will be heated thereby and con-
tinuously vapourize the oil entering it from the supply tank. The other burner-
tubes are each furnished with a cock or valve for controlling the passage of the
vapour from the vapour-chamber to the nozzles, so that by adjusting these cocks
or valves any desired number of the said burner-tubes can be thrown into and out
of action or their flame be reduced in accordance with the temperature required
within the furnace or other place where the said burner is employed. The burner-
tube with which the aforesaid vapourizing coil is arranged, need not be provided
with a cock and valve, 'as it serves as a pilot-burner for keeping the vapourizing
coil always sufficiently heated to ensure vapourizing the oil passing to said coil.
We do not confine ourselves to the use of a coil fór vapourizing the oil as it is
obvious that any other means can be employed for such purpose.
The preliminary heating of the coil or other vapourizing device employed,
may be effected by soaking some suitable substance with the oil and igniting the
same contiguous to the vapourizer so as to raise the temperature of the latter
sufficiently to commence the vapourization and ignite the pilot-burner.
It will be obvious, when the burner-tubes are arranged within a furnace, that
as the burner-tubes are one by one turned on or off the temperature within the
furnace and therefore of the vapourizing coil will rise and fall accordingly, so
that more or less oil-vapour will be generated in accordance with the number of
burner-tubes in operation; the supply of the oil vapour will therefore adjust

page_text: itself to the demand without of necessity requiring special devices for such pur-
pose.

Improvements in and connected with Burners for Use with Liquid
or Gaseous Fuel.
I, BLAND GARDNER SINCLAIR and WALTER SETH WOODWARD, both of 19, Eldon
Street, Finsbury, in the County of London, Engineers, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This invention relates to burners for use with liquid or gaseous fuel and has
for its chief object to provide an atmospheric gas burner which is specially adapted
for burning oil or spirit vapour for heating purposes generally and which can
be very conveniently regulated to burn more or less oil or spirit in accordance
with the amount of heat required.
According to our invention we provide a vapour chamber with which one end of
a vapourizing coil communicates, the other end of such coil being in connection
with the tank or other vessel containing the supply of oil spirit or other liquid
fuel employed. Extending from said chamber is a series of conduits terminating
in nozzles each of which enters a tube formed with perforations and these tubes
constitute the burners proper. Adjacent to the said nozzles where they enter the
said burner-tubes are openings through which external air is induced to flow
into the said tubes by the jets of oil-vapour passing from the nozzles, thereby
causing a mixture of the air and vapour to take place in the tubes before ignition
is effected at the perforations in the said tubes. The aforesaid vapourizing coil
is so arranged with respect to the said burner-tubes that it will be heated thereby
and will continuously vapourize the oil entering it from the supply tank. One
or more cocks or valves are provided for controlling the passage of the vapour to
the nozzles, so that by adjusting these cocks or valves the said burner-tubes can
be thrown into and out of action or their flame be reduced in accordance with the
temperature required within the furnace or other place where the said burner is
employed.
In order that our said invention may be clearly understood and readily carried
into effect we will proceed to describe the same more fully with reference to the
accompanying drawings in which;
Figure 1 is a plan of the burner:
Figure 2 a vertical section on the line 1-1 of Figure 1; and
Figure 3 a vertical section on the line 2-2 of Figure 1;
Figure 4 is an end elevation of the burner as seen from the right.
Figure 5 is a plan of a modified form of the burner.
Figure 6 is an end view of the same looking from the right, the vapour chamber
being in section.
Figure 7 is a vertical section on the line 3, 3, of Figure 6.
Figure 8 is a longitudinal section on the line 4, 4, of Figure 5.
Figures 9 and 10 are sectional plans of modified forms of the burner-tubes.
Like reference letters indicate similar parts in all the figures.

page_text: A is the vapour chamber, B the vapourizer, which is shown in the form of a coil,
and CC are the burner-tubes. One end B' of the vapourizer communicates with the.
said chamber A and the other end B2 of said vapourizer is adapted to be connected
by a suitable union with the oil or spirit tank or reservoir. Extending from
the said chamber A are the conduits A¹ A¹ terminating in nozzles A³, each of
which enters one of the burner-tubes C of which there are three illustrated in
Figures 1 to 4 of the drawings and two in Figures to 8; but it will be evident
that the number of said burner-tubes may be varied in accordance with the purpose
for which the burner is to be used. Adjacent to the said nozzles, the burner-tubes
are formed with the openings C through which external air is induced to flow
into the said tubes by the jets of oil vapour passing from the nozzles, thereby
causing a mixture of the air and vapour to take place in the tubes before ignition
is effected at the perforations CC in the said tubes.
In the burner illustrated in Figures 1 to 4 the aforesaid coil B is situated above
the middle burner-tube so as to be constantly kept heated thereby and to con-
tinuously vapourize the oil entering from the supply tank. The other burner-
tubes are each furnished with a cock or valve C3 for controlling the passage of the
vapour through the conduits A¹, from the chamber A to the nozzles A. By
adjusting these cocks or valves any desired number of the said burner-tubes can be
thrown into and out of action, or their flame be reduced, in accordance with the
temperature required within the furnace or other place where the said burner is
employed. The middle burner-tube, contiguous to which the aforesaid coil B is
arranged, need not be provided with a cock or valve, as it serves as a pilot burner,
which necessarily requires to be kept constantly burning to keep the said coil
always sufficiently heated to ensure vapourizing the oil passing through the said
coil, and also to ignite the other burner-tubes when the oil vapour is admitted
to them by opening their valves or cocks.
In the modified construction illustrated in Figures 5 to 8 we have dispensed
with the said cocks or valves C3 for controlling. the burner-tubes independently
of each other and have provided a valve D which controls the entrance of the
vapour from the vapourizing coil B to the vapourizer A in accordance with the
pressure of steam in the steam generator with which this form of burner is
intended to be used. The construction of this valve is well known, comprising
a cylindrical casing containing a piston d fixed to a piston rod d, the lower
portion of which serves as the valve proper. d² and works through a stuffing box ³.
A spring surrounds the rod and normally tends to keep the valve open.
Steam from the generator enters through the pipe and acts upon the upper
side of the piston. As the pressure of the steam rises it gradually overcomes the
resistance of the spring and causes the valve to gradually cut off the supply of the
vapour to the chamber A. We prefer that the valve shall not completely cut off
the supply, so that the burner will not be entirely extinguished. We furnish the
end B2 of the coil B with a hand.valve B³ for shutting off or regulating the supply
of the oil to the said coil as desired.
We also provide within the burner tubes 'adjacent to the openings C¹, hollow
cones A³ in alignment with the nozzles A2 and at such a distance in advance
thereof that the vapour will be directed into them by said nozzles. In this case
we form apertures c c in the sides of the burner tubes adjacent to the outlet end
of the cones.
The cones are shewn in the example illustrated to be held in place by screws
passing through the burner tubes and entering lateral bosses on the cones.
other suitable means may however be employed for retaining them in place.
Any
In some instances we may employ instead of only one cone, several cones arranged
one in front of the other, in each burner tube.
In Figure 5 we have shewn a perforated disc E located above the vapourizing
coil B. said perforated disc eausing the flames arising from the burner tubes to
more effectually spread over the surface to be heated.
In Figures 9 and 10 we have shewn the burner tubes C bent or made in a

page_text: circular form at the part where the perforations C2 are formed, in which cases a
similar result is attained as when using the perforated disc E.
We do not desire to limit ourselves to the use of a coil for vapourizing the oil,
as it is obvious that any other form of vapourizer can be employed for such
purpose, nor do we wish to confine ourselves to the special manner represented
in the drawings of arranging the said coil in conjunction with the burner-tubes,
as there are a variety of other ways in which the said coil may be disposed:
for instance it might be arranged to spirally embrace one or more of the said
tubes if so desired. The aforesaid vapour chamber may likewise be varied in
shape.
.
The preliminary heating of the said vapourizer can be effected' by soaking some
suitable substance with the oil and igniting the same contiguous to the vapourizer,
so as to raise the temperature of the latter sufficiently to commence the vapouriza-
tion and ignite the burner.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. An atmospheric was burner comprising a series of burner tubes connected
with a
single vapour chamber by nozzles and having air inlet openings adjacent
to said nozzles substantially as and for the purpose specified.
2. The combination with the said burner-tubes and vapour chamber of a
vapourizing coil adapted to be heated by one or more of said burner tubes and of
a valve or valves for regulating the passage of the vapour to the burner-tubes
substantially as described.
3. An atmospheric gas burner having its parts constructed and arranged sub-
stantially as described with reference to either of the examples illustrated in the
accompanying drawings for the purposes specified.
