Improvements in and relating to Hydro-carbon Vapour Burners.
We, THOMAS WILLIAM FLETCHER, Manufacturer of Gas Apparatus, and FLETCHER,
RUSSELL AND COMPANY LIMITED, Manufacturers of Gas Apparatus, both of Thynne
Street, Warrington, in the County of Lancaster, do hereby declare the nature of
this invention to be as follows:-
-
This invention relates to hydro-carbon vapour burners which are especially
applicable for use in heating injection furnaces and the like.
This burner is in communication with a suitable supply of a hydro-carbon, such
as ordinary petroleum, which may be forced by air pressure in any well known
manner to the burner, where it is volatilised and consumed.
In carrying this invention into effect the burner is provided with a helical or
conical coil of suitable tubing one end of which at the base of the coil is in com-
munication with the hydro-carbon supply. The outward end of the coil returns,
preferably outside the coil, to the base, where it is provided with one or more jets
or nozzles for the escape of the vapour. The volatilised hydro-carbon burns inside
and in front of the coil. By this method of construction the vapour is led from the
hottest part of the coil direct to the jets or nozzles. The air necessary to support
combustion is drawn in at the base of the coil which is preferably
arranged in a horizontal or approximately horizontal plane. In end view the coil
may be either circular, elliptical, oval or any other desired shape.
The coil is preferably surrounded by a sheet metal or other casing which may if
desired be provided with a receptacle or the like for spirits, oil or other inflammable
material which is ignited to effect the initial vaporisation of the hydro-carbon con-
tained in the coil so as to enable the burner to be lighted.

We, THOMAS WILLIAM FLETCHER, Manufacturer of Gas Apparatus, and FLETCHER,
RUSSELL AND COMPANY LIMITED, Manufacturers of Gas Apparatus, both of Thynne
Street, Warrington, in the County of Lancaster, 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 hydro-carbon vapour burners which are especially
applicable for heating purposes, as, for example, for use in connection with injection
furnaces and the like.

page_text: communication with the tank or reservoir, with the object of preventing the heating
of the supply tank. The same object may be achieved by forming the pipe itself
with one or more large coils or bends, which in addition to affording a larger
cooling surface, might be so arranged that any hot hydro-carbon tending to flow
backwards from the burner would have to descend one of the bends or coils against
an upwards flow of cool hydro-carbon. Other and well known devices and means
may, if desired, be employed to prevent the transmission of heat from the burner
to the tank.
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. In a hydro-carbon vapour burner a helical or conoidal coil of tubing, one end
of which is connected to the supply of hydro-carbon and the other end of which is
returned to or near the base of the coil and provided with a jet or jets, substantially,
as herein before described and as illustrated by the accompanying drawings.
2. A burner for hydro-carbon vapour, constructed and arranged substantially as
hereinbefore described and as illustrated by the accompanying drawings.
Dated this 17th day of January A.D. 1898.
