Improvements in Vapour Burners.
I OSWALD ROSE of 40 Doddington Grove Kennington in the county of Surrey
Engineer do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide for use burners wherein the vapour of
petroleum and other hydrocarbon oils can be consumed in combination with steam
preferably to produce heat.
To carry out this object I construct of any suitable material a retort wherein are
a series of parallel or other tubes which I call retort tubes and very conveniently
three in number round each of which retort tubes are formed narrow annular
chambers which I call vapour chambers separate from each other and round each
and all of the vapour chambers is formed in the retort one space or chamber which I
call the mixing chamber. The retort tubes pass through the retort and are open at
both ends but the vapour chambers and the mixing chamber are completely closed
and a number of small holes are made in the upper parts of the walls of the vapour
chambers opening into the mixing chamber and the lower parts of the vapour chambers
are filled with asbestos or other fire resisting material. To these vapour chambers
are fitted pipes which lead the water and the hydrocarbon oil thereto entering the
same below the asbestos or other material. 1 preferably so arrange the tanks or
reservoirs of the water and the hydrocarbon oil that these liquids may flow into the
vapour chambers by gravitation and suitable cocks or other appliances are fitted in
the pipes to govern and regulate such flow. When as aforesaid this burner contains
three retort tubes it is most convenient to adinit the water to the vapour chamber
round the central tube and the hydrocarbon oil to the vapour chambers round the
two outside tubes. To the mixing chamber I fit a pipe or pipes wherein one or more
small holes are made out of which the gases can pass and be consumed and the one
or more small holes are so placed that the flame or flames so produced can pass up
the retort tubes. When again as aforesaid the burner contains three retort tubes it
is very convenient to fit two inverted T shaped pipes to the missing chamber the
ends whereof are so arranged that the two middle ends of the Ts approximate to
each other under the central tube while the other ends terminate under the two out-
side tubes whereby a greater heat can be produced in the central tube than in the
two outside tubes.
Underneath the retort is fitted a tray in is placed asbestos wick or other suitable
material.
The action of this apparatus is as follows.
The oil may be allowed to flow through the apparatus until the asbestos wick or
other material in the tray is saturated therewith when this is lighted and the retort
is thus heated thereby or by other convenient means the retort may be heated.
When the due and suitable degree of heat has been attained the water and the hydro-
carbon oil are in the proper quantities allowed to enter the vapour chambers through
the asbestos or other material and are vaporized therein when the resultant vapours
pass through the small holes in the upper parts of the walls of these chambers into
the mixing chamber and then together pass thereout through the pipe or pipes to
the one or more small holes therein where this gas so produced is lighted and the
flame or flames thereof pass up the retort tubes heating the same, and maintaining
the aforesaid vaporization and above these retort tubes the flames can he used for the
desired purpose.
Spreading or deflecting plates can if desired be placed above the retort tubes to
check the passage of the flames through the same.

Improvements in Vapour Burners.
1 OSWALD ROSE of 40 Doddington Grove Kennington in the county of Surrey
Engineer 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:
The object of this my invention is to provide a burner wherein the vapour of
petroleum and other hydrocarbon oils can be consumed in combination with steam
or the vapour of water and the resultant flame or flames can be used to give
light or produce heat as may be desired.
In order the more clearly to explain my invention and in what manner the same
is to be performed I refer to the accompanying drawings in which I have shewn one
and what I consider to be one of the best and most efficient and convenient forms
and styles of this my vapour burner whereof Figure 1 is a transverse vertical section
taken at c d in Figure 2 and Figure 2 is an horizontal sectional plan taken at a bin
Figure 1.
I construct of any suitable materia! such for example as cast iron a retort wherein
are a series of tubes A which I call retort tubes and preferably as is shewn in the
drawings I so arrange these tubes A in the retort that three of them are in line with
each other and that there are two of such lines of three tubes in the retort at right
angles to each other the central retort tube A¹ being common to both lines and round
each retort tube A is constructed and formed a narrow annular chamber B which [
call a vapour chamber and round or about each and all of the vapour chambers B is
constructed and formed in the retort one space or chamber C which I call the mixing
chamber. The retort tubes A pass through the retort and are open at both ends but
the vapour chambers B and the mixing chamber are completely closed and a number
of small holes D are made in the upper parts of the walls between the same leading
from each of the vapour chambers B into the mixing chamber and the lower parts
of the vapour chambers B may be filled with asbestos or other heat resisting material
or as is perhaps preferable and as is shewn in the drawings a separate chamber E for
the asbestos or other material may be constructed and formed below each vapour
chamber B communicating therewith by the small passage or passages F.
Communicating with the lower parts of the vapour chambers B or when so
constructed and formed with the chambers E I fit pipes which lead the water and the
hydrocarbon oil separately thereto causing the same to pass through the asbestos or
other material and I may so arange the tanks or reservoirs thereof and use with the
same such ordinary appliances that the water and the hydrocarbon oil will flow through
these pipes into the retort by gravitation or by pressure or otherwise and suitable
cocks or other appliances can be fitted in the pipes to govern and regulate such flow.
When the retort is constructed as is shewn in the drawings it is most convenient to
lead the water through the pipe G to the chamber round the central retort tube A¹
and the hydrocarbon oil through the pipe H to the chambers round the outside retort
tubes A.
Communicating with the mixing chamber CI fit one or more pipes wherein one
or more small burner holes are made out of which the vapour can pass to be consumed
and these burner holes are so placed that the flames so produced can pass up the
retort tubes. When the retort is constructed as is shewn in the drawings it is most
convenient to fit to the mixing chamber C four pipes K of an inverted T shape the
arms L whereof are so arranged that the ends of one of the arms I of all the pipes K
approximate to each other under the central retort tube A¹ while the other arm L of
each pipe K terminates under one of the outside retort tubes A and the small burner
holes Mare made near the ends of these arms L in the proper positions under the
retort tubes A by which arrangement it is obvious that a greater heat will be produced
in the central retort tube A than in the outside retort tubes A and this is
desirable.

page_text: When the retort is constructed as is shewn in the drawings in order to maintain
the temperature in the mixing chamber C and to prevent any danger of condensation
therein it is most convenient to make passages N therethrough between the retort
tubes A which passages N are preferably tapered as is shewn that is to say are
larger at the upper surface of the retort than at the lower surface thereof and
these passages N are so arranged in the retort that other small burner holes P
made in the arms I of the pipes K shall be directly thereunder whereby the flames
from these burner holes P shall pass up the passages N.
Underneath this retort can be provided a tray R in which is placed asbestos wick
or other similar or suitable material.
The method of using this apparatus and the action thereof are as follows.
The retort is first heated by any convenient and extraneous means and when as
aforesaid a tray R is provided the asbestos wick or other material therein is saturated
with oil preferably by allowing or causing the same to flow through the retort there-
upon and then lighted to heat the retort. When the due required and suitable heat
has been attained in the retort the water and the hydrocarbon oil are in the proper
quantities allowed or caused to flow through the pipes G and H and enter their
respective vapour chambers B either through the asbestos or other material therein if
any or as is shewn in the drawings through the asbestos or other material in the
chambers E and thence through the passages F and in these chambers B the liquids
are vaporized and the resultant vapours pass through the small holes D into the
chamber C where they are mixed together and by the heat of this chamber Care
fixed in the vaporized condition and then pass thereout through the pipes K and arms L
to the burner holes M where this combined vapour so produced as aforesaid is lighted
and the flames thereof pass up the retort tubes A heating the same and maintaining
and continuing the aforesaid vaporization when the extraneous heat can be dispensed
with while if so constructed the flames from the burner holes P pass up the passages N
maintaining the temperature in the mixing chamber C and above the retort tubes A
and the passages N if any the flames can be used for the desired purpose whether to
give light or heat.
Spreading or deflecting plates can if desired be placed above the retort tubes A
and the passages N if any to check the passage of the flames therethrough and to
spread out the flames above the retort.
I have thus described and I have shewn in the accompanying drawings as is
herein before stated what I consider to be one of the best and most efficient and
convenient forms and styles of my vapour burner but it is obvious and I would have
it clearly understood that I do in no wise limit myself thereto for this my vapour
burner may be constructed with two or any greater number of retort tubes with their
separate surrounding vaporizing chambers in all cases one mixing chamber being
cominon to both or all these vaporizing chambers and the exit pipe or pipes from
this mixing chamber may be so arranged and formed as may be necessary to cause
the burner holes therein to be in their required positions as herein before described and
in the smaller burners it may not be necessary to make the passages through the
mixing chamber while the whole apparatus and all the several parts thereof may be
constructed and fitted and arranged and formed in such a manner and of such shapes
as may be convenient or desirable in each particular case.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The vapour burner consisting of a vaporizing chamber for water surrounding
a retort tube a vaporizing chamber or chambers for hydrocarbon oil also surrounding
a retort tube or tubes and a mixing chamber common to and communicating with
both or all the vaporizing chambers from which mixing chamber the combined
vapour is conducted to positions below the retort tubes and there consumed to heat
the same substantially as herein before set forth.

page_text: 2. The combination in a vapour burner of two or more retort tubes A two or
more surrounding vapour chambers B provided with asbestos or other material a
common mixing chamber C communicating with the vapour chambers B and a pipo
or pipes K with burner holes M substantially as and for the purpose herein before
described and declared.
3. The combination in a vapour burner of two or more vapour chambers B whereto
the water and the hydrocarbon oil are separately led through asbestos or other material
each vapour chamber B surrounding a retort tube A common mixing chamber (
communicating with the vapour chambers B and formed with passages N there-
through and a pipe or pipes K fitted to the mixing chamber and provided with
burner holes M and P wherein the vapour is consumed and the resultant flames pass
up the retort tubes A and the passages N substantially as and for the purposes herein-
before described and declared."
