Heat from Puddling, Forge, Mill, or other Furnaces.
We, WILLIAM BEESLEY and JAMES BEESLEY, both of the Furness Boiler Works,
Barrow-in-Furness, in the County of Lancaster, Boiler Makers, do hereby declare the
nature of this invention to be as follows:-
According to this invention we employ a horizontal cylindrical boiler, arranged
above the puddling, forge, mill, or other furnace, resting on metal saddles or cross
girders carried on supporting columns or pillars standing on each side of the
furnace.
The boiler consists of an ordinary cylindrical shell with three inner tubes running
lengthwise of the boiler, one of the tubes of larger diameter than the others-being
placed near the bottom of the shell and the other two smaller tubes at a higher level
in the same horizontal plane. In the large lower tube we prefer to introduce cross
tubes of the Galloway type. The waste heat passes up from the neck of the furnace
through a vertical flue and, in one arrangement, enters at one end of the large
lower tube through which it passes and emerges into an end chamber at the opposite
end of the boiler where it is divided and returns through the two upper smaller tubes
to meet again in a suitable connecting flue and be carried off to an uptake or a down-
take as may be convenient communicating with the main flue to the smoke or chimney
stack. Each boiler may be arranged to carry its own chimney by making the con-
necting flue in the form of a smoke box fastened on the boiler end; the waste heat
passing upwards therefrom into a chimney tube above, which may be carried to any
convenient height. The end or dividing chamber preferably consists of an internal
box (constructed of boiler plating and suitably stayed) so arranged as to be surrounded
by the water in the boiler. Or, in lieu of an end chamber, junction tubes leading
diagonally from the lower large tube, one to each of the upper smaller tubes, may be
conveniently employed.
In this case the ends of the three boiler tubes adjoining the junction tubes would be
closed or made up, preferably with plating lined with refractory material.
The improved boiler may, if desired, he constructed in a double form, that is to say,
the arrangement of tubes, and end or dividing chamber or junction tubes as the case
[Price 8d 1

dividing chambers or two sets of junction tubes with a mid-feather or plate between
them centrally in the boiler and admitting the waste heat from both ends of the
boiler; the effect resembling that which would obtain if two single boilers as first
hereinabove described were arranged end to end.
Instead of admitting the waste heat horizontally at one end of the lower large tube
from the vertical flue communicating with the neck of the furnace as above described,
it may be admitted vertically by closing the end of the tube and employing a metal
flue lined with refractory material passing down from the lower side of the large tube
through the bottom of the boiler into the neck of the furnace below.
We preferably cover our improved boiler, supported on metal saddles or cross
girders as above described, with non-conducting composition or material and thus do
without brickwork and consequent liability to corrosion; moreover, accessibility for
purposes of inspection is thereby more readily afforded.

Heat from Puddling, Forge, Mill, or other Furnaces.
We, WILLIAM BEESLEY and JAMES BEESLEY, both of the Furness Boiler Works,
Barrow-in-Furness in the County of Lancaster, Boiler Makers, 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 :-
According to this invention we employ a horizontal cylindrical boiler, arranged
above the puddling, forge, mill, or other furnace, resting on metal saddles or cross
girders carried on supporting columns or pillars standing on each side of the furnace.
The boiler consists of an ordinary cylindrical shell with three inner tubes running
lengthwise of the boiler, one of the tubes-of larger diameter than the others-being
placed near the bottom of the shell and the other two smaller tubes at a higher level
in the same horizontal plane with each other. In the large lower tube we
prefer to
introduce cross tubes of the Galloway type. The waste heat passes up from the neck
of the furnace through a vertical flue, and, in one arrangement, enters at one end of
the large lower tube, through which it passes and emerges into an end chamber at the
opposite end of the boiler, where it is divided and returns through the two upper,
smaller tubes to meet again in a suitable connecting flue and be carried off to an up-
take or a downtake, as may be convenient, communicating with the main flue to the
smoke or chimney stack. Each boiler may be arranged to carry its own chimney by
making the connecting flue in the form of a smoke box fastened on the boiler end;
the waste beat passing upwards therefrom into a chimney tube above, which may be
carried to any convenient height. The end or dividing chamber preferably consists
of an internal box (constructed of boiler plating and suitably stayed) so arranged as
to be surrounded by the water in the boiler. Or, in lieu of an end chamber, junction
tubes leading diagonally from the lower large tube, one to each of the upper smaller
tubes, may be conveniently employed. In this case the ends of the three boiler tubes
adjoining the junction tubes would be closed or made up, preferably with plating lined
with refractory material.
The improved boiler may, if desired, be constructed in a double form, that is to say,
the arrangement of tubes, and end or dividing chamber or junction tubes as the case
may be as above described, may be duplicated in the same boiler by placing two
dividing chambers or two sets of junction tubes with a mid-feather or plate between
them centrally in the boiler and admitting the waste heat from both ends of the
boiler; the effect resembling that which would obtain if two single boilers as first
hereinabove described were arranged end to end.
Instead of admitting the waste heat horizontally at one end of the lower large tube
from the vertical flue communicating with the neck of the furnace as above described,
it may be admitted vertically by closing the end of the tube and employing a metal
Alue lined with refractory material passing down from the lower side of the large tube
through the hottom of the boiler into the neck of the furnace below.
We preferably cover our improved boiler supported on metal saddles or cross girders
as above described, with non-conducting composition or material and thus do without
brickwork and consequent liability to corrosion; moreover, accessibility for purposes
of inspection is thereby more readily afforded.

page_text: In the accompanying drawings Fig. 1 is an end elevation; Fig. 2 a side elevation
partly in section; Fig. 3 a cross section; and Fig. 4 a.sectional plan-showing the
construction of one form of our improved steam boiler with attendant arrangements as
hereinabove described.
A represents an ordinary re-heating furnace from which the waste heat passes up
the neck B lined with refractory material C. D is the outer cylindrical shell of the
boiler; E the large lower tube; and FF the two upper smaller ones. GG are cross
tubes of the Galloway type. H is the end chamber into which the waste heat from the
large lower tube emerges, when it is divided and returns through the two upper
smaller tubes FF to meet again in the connecting flue I and be carried off in the
downtake J to the smoke or chimney stack. K is a damper with chain and balance
weight mechanism as shown. LL are saddles or cross girders carried on the pillars or
supporting columns M M.
Figs. 5 and 6 are respectively a sectional plan and a cross section showing the
arrangement hereinbefore mentioned in which junction tubes NN leading diagonally
from the lower large tube, one to each of the smaller upper tubes FF are employed
in lieu of an end dividing chamber H shown in Figs. 2, 3, and 4. We prefer to close
or make up the ends of the three flues by means of hinged doors 00 lined with
refractory material C, the doors providing a convenient means of access to the interior
of the tubes for cleaning or other purposes.
Fig. 7 is a sectional view illustrating the mode of admitting the waste heat
vertically from the furnace neck B into the large lower tube E hereinbefore referred
to. In this arrangement also we prefer to close the end of the tube E with a hinged
door lined with refractory material C.
We prefer to form the lower large tube E with recesses or water pockets P (as
shown in Figs. 2, 3, and 4) to admit of access to the spaces underneath the three
tubes. The water pockets P also provide additional heating surface against which the
waste heat may impinge in its passage through the tube E (see Fig. 3).
Although we have described and shown in the drawings our improved boiler
arranged over the furnace it may if found more convenient be placed on one side
thereof and the arrangement of connecting flues may be varied to suit the altered
circumstances.
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. Constructing horizontally arranged steam boilers with a lower tube through which
waste heat from puddling, forge, mill, or other furnaces is first passed in one direction
into an internal end or dividing chamber and is then passed back again through the
boiler within upper tubes substantially as described and shown in Figs. 2, 3, and 4 of
the drawings.
2. In steam boilers for utilizing the waste heat from puddling, forge, or other
furnaces, the mode of connecting a lower tube E with upper tubes FF by means of
junction tubes NN substantially as described and shown in Figs. 5 and 6 of the
drawings.
3. In steam boilers for utilizing the waste heat from puddling, forge, mill, or other
furnaces, the mode of connecting a lower tube E with the neck B of a furnace
substantially as described and shown in Fig. 7 of the drawings.
