PROVISIONAL SPECIFICATION.
A New or Improved Apparatus for Burning Creosote and similar
Oil for Steam Generating and Heating Purposes.
I, WILLIAM ALLEN, of Ancoats, Manchester, Engineer, do hereby declare the
nature of my said invention to be as follows:-
My invention has for its object the construction of an improved burner for
burning creosote and other similar inflammable oils for use in connection with
steam generators and for heating purposes.
In carrying out my invention I employ high pressure steam to spray the oil
onto the furnace, and valves, tubes and connections for carrying this out in a
convenient manner.
The improved apparatus consists of a pair of tubes one within the other,
whereof the centre one forms the oil supply and the annular space between this
central tube and the said outer tube the steam passage. Both these tubés
terminate in a valve body having two side branches, one of which communicates
with the oil supply through a suitable valve or regulator and the other with a
steam supply through a suitable valve or regulator.
The oil supply to the central tube is further controlled by a valve in the
valve body aforesaid, and immediately at the entrance of the central pipe.
My improved apparatus is mounted say in the case of a steam boiler at the
front of the furnace and the spraying pipe is lead some distance into the furnace
and is inclined in the direction of the fire bars. Said fire bars are however
covered with fire brick and slag for the apparatus to play upon.
In starting the burner a small coal or cinder fire is lit on the fire brick and
the oil and steam being now turned on, the same driven in a minute state of
division or fine spray on to the coke fire when the oil immediately ignites and
forms an intense flame and heating medium. The flow of steam into the burner
is regulated by the valve aforesaid and the oil supply by the valve at the
mouth of the central pipe. Once this regulation is effected it need not be
disturbed or only occasionally, the oil being shut off by a main valve.

A New or Improved Apparatus for Burning Creosote and similar
Oil for Steam Generating and Heating Purposes.
1, WILLIAM ALLEN, of Ancoats, Manchester, Engineer, do hereby declare the
nature of my said invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
My invention has for its object the construction of an improved burner for
burning creosote and other similar inflammable oils for use in connection with
steam generators and for heating purposes.
In carrying out my invention I employ high pressure steam to spray the oil
on to the furnace, and valves, tubes and connectious for carrying this out in a
convenient manner

The improved apparatus consists of a pair of tubes one within the other,
whereof the centre one forms the oil supply and the annular space between this
central tube and the said outer tube the steam passage. Both these tubes
terminate in a valve body having two side branches, one of which communicates
with the oil supply through a suitable valve or regulator and the other with a
steam supply through a suitable valve or regulator.
The oil supply to the central tube is further controlled by a valve in the
valve body aforesaid, and immediately at the entrance of the central pipe.
My improved apparatus is mounted say in the case of a steam boiler at the
front of the furnace and the spraying pipe is lead some distance into the
furnace and is inclined in the direction of the fire bars. Said fire bars are
however covered with fire brick and slag for the apparatus to play upon.
In starting the burner a small coal or cinder fire is lit on the fire brick and
the oil and steam being now turned on, the same is driven in a minute state of
division or fine spray on to the small fire when the oil immediately ignites and
forms an intense flame and heating medium. The flow of steam into the burner
is regulated by the valve aforesaid and the oil supply by the valve at the
mouth of the central pipe. Once this regulation is effected it need not be
disturbed or only occasionally, the steam and oil being shut off by main valves.
And in order that my said invention shall be the more readily understood
and carried into practical effect I have hereunto annexed a sheet of drawings
and will now proceed to describe the same with the assistance of the various
figures and letters of reference marked thereon.
Fig. 1 is a front exterior view, Fig. 2 a side sectional view and Fig. 3 a
sectional plan of my improved oil burning apparatus; Fig. 2 shewing the position
of the burner relatively to a steam boiler furnace.
In accordance with my invention I employ a pair of tubes (A) (A'), the latter
within the former and sufficiently small to produce an annular space between
the two tubes. Both tubes (A) and (A') are secured to the valve body (B)
which is formed with two side branches (C) and (D), the side branch (C) under
the control of the valve (E), communicating with the steam supply and the side
branch (D) under the control of the valve (F), communicating with the oil
supply. By opening such valves oil will pass into the tube (A') and steam will
pass into the tube (A) as indicated by the arrows.
The oil supply to the central tube is further controlled by the valve (G) in
the valve body (B).
The improved apparatus is mounted in the case of a steam boiler at the front
of the furnace and the spraying pipes (A), and (A') extend some distance into
the furnace and are inclined in the direction of the grate, preferably at an angle
of about 15 degrees from the furnace crown. In applying my improved apparatus
to existing steam boiler furnaces the fire bars are covered with fire brick and
slag for the apparatus to play on.
In starting the burner as already described, a small coal or cinder fire is lit on
the fire brick and the oil and steam being then turned on the same is driven in a
minute state of division or fine spray onto the small fire when the oil immediately
ignites and forms an intense flame and heating medium.
The oil is supplied to the burner by the ejection action of the steam issuing from
the annular passage.
Once the regulation of the valve (G) is effected it need not be disturbed, or
only occasionally, the steam and oil being shut off by the valves (E) and (F)
respectively.
It will be obvious that the oil may be arranged to enter the pipe (A) and the
steam (A') with a more or less similar effect, but I have found the method
previously described the most convenient in practise.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood

page_text: that I do not confine myself to the precise form, relative proportions and dimensions
of my improved oil burner as the same may be varied to suit particular applications
and purposes without departing from my invention and what I claim and desire to
secure by Letters Patent is.
In apparatus for burning oil for steam generating and heating purposes the use
and employment of a valve body carrying oil and steam spraying pipes and
communicating with oil and steam supplies respectively under the control of
valves or their equivalents arranged and mounted substantially as set forth and
illustrated.
