PROVISIONAL SPECIFICATION.
Improvements in or connected with Steam Generator and other
Furnaces.
WE, JOHN SUTTON, of The Grapes Hotel, Formby, in the County of Lancaster,
Master Mariner, and JOHN WILLIAM BUCKLEY, of Cable Street, Formby, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention to
be as follows: —
This invention has reference to the furnaces of steam generators and other
furnaces, but for convenience we will describe its nature as applied to the furnaces
of steam generators.
In the furnace space of a steam generator, we provide on each side, inclined
fuel plates or bearers, and preferably at the lower part thereof apertures are
provided for the admission of air and steam, as hereafter described. Then again
at the bottom a suitable aperture or space is provided to let out the dust and other
matter it is desired to remove. In the front of the furnace suitable doors are
provided, in one or more of which under the fire bearers, apertures with suitable
means of regulating same are provided to admit air, while steam pipes are also led
to this space or spaces to admit and deliver steam, which, mixing with the air,
passes from said spaces into the fuel at the bottom of the fire bearers, and passes
upwards through the depth of fuel, which, by the arrangement according to this
invention, is of considerable depth. The effect of this arrangement and invention
is that clinkers are prevented from forming; a great saving of fuel 18 effected;
the formation of smoke is prevented; a saving of labour is effected; and the fuel
or fire will last relatively a long time for a given amount of fuel burned.
Above the level of the fuel and in front or at other suitable parts of the furnace,
a firing door, or doors for the introduction of fuel is or are provided.
Of course it is to be understood, in applying this invention, to different kinds of
furnaces, the arrangement, combination, and construction of parts will necessarily
be inodified to suit the different conditions of its application.

COMPLETE SPECIFICATION.
Improvements in or connected with Steam Generator and other
Furnaces.
We, JOHN SUTTON, of the Grapes Hotel, Formby, in the County of Lancaster,
Master Mariner, and JOHN WILLIAM BUCKLEY, of Cable Street, Formby, in
the County of Lancaster, 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:-
This invention has reference to the furnaces of steam generators and other
furnaces, but for convenience we will describe its nature as applied to the furnaces
of steam generators.
In the furnace space of a steam generator, we provide on each side, inclined
fuel plates or bearers, with apertures provided therein for the admission of air
and steam, as hereafter described. Then again at the bottom a suitable aperture
or space is provided to let out the dust and other matter it is desired to remove.

page_text: In the front of the furnace suitable doors are provided, and under the fire bearers,
apertures with suitable means of regulating same are provided to admit air, while
steam pipes are also led to this space or spaces to admit and deliver steam, which,
mixing with the air, passes from said spaces into the fuel at the bottom of the fire
bearers, and passes upwards through the depth of fuel, which by the arrangement
according to this invention, is of considerable depth. The effect of this arrange-
ment and invention is that clinkers are prevented from forming; a great saving of
fuel is effected; the formation of smoke is prevented; a saving of labour is
effected; and the fuel of fire will last relatively a longer time for a given amount
of fuel burned.
Above the level of the fuel and in front or at other suitable parts of the furnace,
a firing door, or doors for the introduction of fuel is or are provided.
The drawings appended to this Specification illustrate a Cornish or other
internally fired steam generator provided with our improvements. In these
drawings,
Figure 1 is a longitudinal section through the furnace flue shewing the interior
construction of our furnace; Figure 2 is a cross section through same; and
Figure 3 is a front outside view.
Referring to the drawings, a is the furnace flue; b is the furnace front plate;
and c are the fuel bearing plates.
The plates c are supported at their outer edges by contact with the furnace
flue a, and at their lower ends by feet d, which rest upon the bottom of the furnace
flue, such feet being fitted or fastened in the plates in any suitable way. The
lower edges of the plates abut against each other at each end where they are
provided with projections e. Although each half the fuel bearers may consist
of a single plate, yet we prefer to form the grate of a number of plates, such as
shewn any suitable number of plates may be used.
h
The plates c, as will be seen, are provided with holes or apertures f, beneath
which steam pipes are provided, from which jets of steam issue opposite each
hole, and aid in forcing in air and assisting in complete combustion of the fuel.
The edges of the plate are recessed at i, as onewn, and these recesses also admit
air into the fuel. The longitudin lapertures k at the bottom of the furnace plates
serve chiefly to allow of ashes falling through the grate, and partly enable clinkers
or other incombustible matters, should they occasionally be formed, to be removed.
The front of the arnace is provided at the bottom with a door 1, through which
access may be had to the space under the furnace in which the ashes fall and
through which they may be removed. At each side of this door the front plate b
is open up to the level of the plates c, and through the apertures, air passes to the
space below the said plates. Also the steam pipes are introduced through these
apertures, and they are coupled up to a main steam supply pipe m outside the
furnace front. o is the ordinary fire door through which the fuel is charged into
the furnace, and p is the ordinary bridge at the back of the furnace.
A large depth of fuel is preferably maintained on the plates c, and air and steam
are forced through the fuel, by way of the holes or apertures f, and a very efficient
and perfect combustion takes place; also, the formation of clinkers is wholly or
very nearly obviated and relatively a very small quantity of solid matter falls
through the grate into the ash-pit, and what does so fall through, is purely ash.
By the use of this furnace, the rate of steam production of a steam generator may
be increased over that produced in the ordinary way, and at the same time with a
large saving of fuel, and economy in fire bars or bearers is effected. Furthermore,
small and cheap qualities of coal can be used and burned with advantage on this
grate, and the formation of smoke prevented.
It is to be remarked in conclusion that the invention is not confined to the
particular disposition of plates and apertures therein, as shewn in the draw-
ings, nor to the particular mode of supporting saine, or the fittings illustrated; and
in the application of it to different forms of steam generators, it may be modified
to suit the different conditions of such application.

page_text: Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. A steam generator or other analogous furnace, consisting of plates, such as c,
arranged within the flue or furnace of the generator, and steam pipes arranged or
adapted to discharge jets of steam through apertures and force air into the fuel;
substantially as herein set forth.
2. The steam generator furnace having its parts arranged, combined, and con-
structed particularly as shewn in and set forth with reference to the drawings.
