A NEW OR IMPROVED BURNER FOR COMBUSTION OF LIQUID HYDROCARBONS
Year: 1883

page_text: LETTERS PATENT to Matthew Forrest Perry of West Hartlepool in the
County of Durham for an Invention of "A NEW OR IMPROVED BURNER FOR
COMBUSTION OF LIQUID HYDROCARBONS
"
PROVISIONAL SPECIFICATION left by the said Matthew Forrest Perry at
the Office of the Commissioners of Patents on the 8th September 1883.
MATTHEW FORREST PERRY of West Hartlepool in the County of Durham
"A NEW OR IMPROVED BURNER FOR COMBUSTION OF LIQUID HYDROCARBONS
"
My invention relates to a burner for effecting combustion of liquid hydrocarbons,
such as mineral or other oils or liquid residues thereof after distillation. I provide
a steam pipe which terminates in an annular nozzle adjustable by a screw, so that
an annular film of steam of greater or less thickness can be made to issue from it.
Around this steam pipe there is a larger pipe enclosing an annular passage through
which the liquid fuel passes to an annular nozzle surrounding the steam nozzle,
this nozzle being also adjustable by a screw, by which the thickness of the issuing
annular film of liquid can be adjusted. In some cases, I provide, within the steam
pipe, a pipe which conducts air to the centre of the circular nozzle. I preferably.
mount the apparatus as a bracket on a joint to which the steam and fuel pipes are
connected, so that it can be turned on the joint to be directed through a hole in the
fire door or front of a boiler, or it can be turned outwards for adjustment. This
joint may be made with passages through its plug, to act as a stop cock, cutting
off the flow of steam and fuel in one position to which the apparatus may be
turned.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Matthew Forrest Perry in the Patent Office on the 8th March
1884.

an annular film of steam of greater or less thickness can be made to issue from it.
Around this steam pipe there is a larger pipe enclosing an annular passage through
which the liquid fuel passes to an annular nozzle surrounding the steam nozzle,
this nozzle being also adjustable by a screw by which the thickness of the
annular film of liquid can be adjusted. In some cases, I provide within the steam
pipe a pipe which conducts air to the centre of the circular nozzle. I preferably
mount the apparatus as a bracket on a joint to which the steam and fuel pipes are
connected, so that it can be turned on the joint to be directed through a hole in the
fire door or front of a boiler, or can be turned outwards for adjustment. This
joint may be made with passages through its plug to act as a stop-cock, cutting
off the flow of steam and fuel in one position to which the apparatus may be
turned.
Fig. 1 of the accompanying drawings is a front elevation and fig. 2 is a plan
shewing how the burner is applied to the fireplace of a boiler. Figs. 3 and 4 are
longitudinal sections of the burner-tube and nozzle. On a bracket projecting from
the boiler front is fixed a joint A fitted in the manner of a stopcock and having in
it passages for steam and oil, the steam entering the stationary plug by a pipe S
and the oil by a pipe O. From the socket of the joint, steam and oil pipes S¹
and O¹ lead to the burner tube T each of those pipes being provided with a cock
or valve which can be delicately adjusted so as to proportion as required the
relative quantities of steam and oil. The passages of the joint A are so arranged
that when the apparatus is in the working position, as shewn in fig. 2, they are
open; but when the burner and pipe are swung back on the joint A as on a hinge,
the passages of A are closed. The burner tube projects through a round hole cut
in the fire door F, and within this hole there is attached to the fire door a conical
casing C and several screens of wire gauze W which distribute and diffuse the
current of entering air, the direct passage of air being prevented by a collar M
surrounding the burner tube. This tube, as shewn in fig 3, consists of an inner
pipe P through which the steam passes from S', and an outer pipe T forming
around P an annular passage for oil from 0¹. At the mouth of P there is a coned
screw plug B with passages b through it. By screwing this plug more or less
closely into its coned seat at the mouth of P, the annular film of steam issuing at s
can be regulated. On the outer pipe T is, fitted a screwed socket by which, in like
manner, can be regulated the annular film of oil issuing at o When a central air
supply is desired, the burner is modified, as shewn in fig 3, a central air tube E
being fitted in it.
Having thus described the nature of my
same is to be performed, I claim :--
The construction of burner for effecting
substantially as herein described
invention and in what manner the
combustion of liquid hydrocarbons,
In Witness whereof, I the said Matthew Forrest Perry have hereunto set my
hand and seal this fourth day of March in the year of our Lord, one thousand,
eight hundred and eighty four.
