Improvements in the Construction of and in Connection with Steam
Boilers arranged to Utilize the Waste Heat from Puddling, Forge,
Mill, or other Furnaces.
I, WILLIAM BEESLEY, of the Furness Boiler Works, Barrow-in-Furness, in the
County of Lancaster, Boiler Maker, do hereby declare the nature of this invention
to be as follows :-
This invention has for its object the construction of a steam generator or boiler
and in arranging it in conjunction with a puddling, forge, mill, or other furnace so as
to utilize the waste heat therefrom. In the ordinary arrangement of steam boiler
heretofore employed for this purpose the boiler is of the horizontal cylindrical type
and is placed above the furnace from which the waste heat is evolved and occupies
a considerable amount of overhead space or room. In many instances the required
overhead space or room is not always available and according to this my invention
adopt a vertical form of boiler having a large heating surface into one side of
which the waste heat directly enters horizontally in a line with the outlet flue of the
furnace and finds its way in a downward direction through a group of quadrant shaped
tubes (surrounded by water) through the bottom of the boiler and into an ordinary
underground horizontal outlet or carrying off flue. The improved boiler consists
of a vertical cylindrical shell having a top of any desired shape and having suitable
outlet holes for the steam pipe safety valve and other usual accessories of a steam
boiler and having a flat circular bottom plate. At that side of the boiler adjoining
the outlet end of the furnace is a circular flat plate standing vertically and sur-
rounded by a projecting flange of boiler plating which is arranged to form a junction
with the outlet flue or opening of the adjoining furnace from which the waste heat
issues. Into the said vertical side plate is inserted the upper end of each of the
quadrant shaped tubes forming the group hereinbefore referred to the other or lower
ends of the tubes being inserted in the flat horizontal bottom plate of the boiler.
By the above described arrangement the waste heat from the furnace is caused to
enter the upper ends of the quadrant shaped tubes horizontally and passing through
the said tubes downwardly issues therefrom in a downward vertical direction and
escapes into the outlet flue below as hereinbefore mentioned.
1 make the quadrant shaped tubes preferably of larger internal diameter than
tubes usually employed in tubular steam generators.
The surrounding flange plate forming the junction with the furnace flue from
which the waste heat issues may be lined internally with fireclay or other refractory
material and may be provided with a suitable door or opening to afford access to
the interior of the junction for the removal of flue dust or for other purposes.
Dated this 1st day of October 1890.

Improvements in the Construction of and in Connection with Steam
Boilers arranged to Utilize the Waste Heat from Puddling, Forge,
Mill, or other Furnaces.
I, WILLIAM BEESLEY of the Furness Boiler Works, Barrow-in-Furness, in the
County of Lancaster, Boiler Maker, 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 for its object the construction of a steam generator or boiler
and in arranging it in conjunction with a puddling, forge, mill, or other furnace so
as to utilize the waste heat therefrom. In the ordinary arrangement of steam
boiler heretofore employed for this purpose the boiler is of the horizontal cylindrical
type and is placed above the furnace from which the waste heat is evolved and
occupies a considerable amount of overhead space or room. In many instances the
required overhead space or room is not always available and according to this my
invention I adopt a vertical form of boiler having a large heating surface into one
side of which the waste heat directly enters horizontally in a line with the outlet
flue of the furnace and finds its way in a downward direction through a group of
quadrant shaped tubes (surrounded by water) through the bottom of the boiler and
into an ordinary underground horizontal outlet or carrying off flue. The improved
boiler consists of a vertical cylindrical shell having a top of any desired shape and
having suitable outlet holes for the steam pipe safety valve and other usual
accessories of a steam boiler and having a flat circular bottom plate. At that side
of the boiler adjoining the outlet end of the furnace is a circular flat plate standing
vertically and surrounded by a projecting flange of boiler plating which is arranged
to form a junction with the outlet flue or opening of the adjoining furnace from
which the waste heat issues. Into the said vertical side plate is inserted the upper
end of each of the quadrant shaped tubes forming the group herein before referred
to the other or lower ends of the tubes being inserted in the flat horizontal bottom
plate of the boiler. By the above described arrangement the waste heat from the
furnace is caused to enter the upper ends of the quadrant shaped tubes horizontally
and passing through the said tubes downwardly issues therefrom in a downward
vertical direction and escapes into the outlet flue below as hereinbefore mentioned.
I make the quadrant shaped tubes preferably of larger internal diameter than
tubes usually employed in tubular steam generators, although I have found in
practice that tubes of the ordinary diameter are equally efficient for the purpose of
my invention.
The surrounding flange plate forming the junction with the furnace flue from
which the waste heat issues may be lined internally with fireclay or other refractory
material and may be provided with a suitable door or opening to afford access to
the interior of the junction for the removal of flue dust or other purposes.

said invention.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The construction of steam boiler arranged to receive waste heat horizontally at
the side of the boiler the said waste heat passing downwardly through quadrant
shaped or curved tubes and emerging from the said tubes in a downward vertical
direction substantially as hereinabove described and shewn in the accompanying
drawings for the purpose set forth.
