IMPROVEMENTS IN VERTICAL STEAM GENERATORS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
1, WILLIAM GARNER of Perseverance Boiler Works Salford, in the county of
Lancaster, Engineer, do hereby declare the nature of my said invention for
IMPROVEMENTS IN VERTICAL STEAM GENERATORS to be as follows:-
The object is to provide a vertical or upright steam generator of simple
construction having ample water space and heating surface so made and disposed
as to ensure improved combustion and prevention of smoke, to utilize to the best
advantage the heat given out by the burning fuel and to allow easy access to all
the parts for cleaning and repairs.
A steam generator constructed under my invention consists essentially of a
cylindrical or nearly cylindrical shell within which a furnace, a group of downtake
and a group of uptake fire or flue tubes are disposed in three sections substantially
as hereinafter set forth.
The furnace is cylindrical or more advantageously in the form of the frustrum of
a cone, is placed excentrically within the shell, and is provided at the top with a
dome, shaped so as to project sideways or horizontally from the furnace for about
one third of its circumference; from the underside of the projecting portion of the
dome a group of fire or flue tubes lead downwards through the waterspace to a flue
beneath the generator leading partly around the said generator, to a second group
of fire or flue tubes which latter lead up through the water space to the chimney.
The furnace grate and firing door are of any usual or suitable description, bafflo
plates are provided if desired to direct the flow of the heated gases and products of
combustion and doors or movable plates or partitions permit of access to the various
parts.

I, William GARNER of Perseverance Boiler Works Salford in the County of
Lancaster, Engineer, do hereby declare the nature of the said invention for
"IMPROVEMENTS IN VERTICAL STEAM GENERATORS" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :—
The object is to provide a vertical or upright steam generator of simple
construction having ample water space and heating surface so made and disposed
as to ensure improved, combustion and prevention of smoke to utilize to the best
advantage the heat given out by the burning fuel and to allow easy access to all
the parts for cleaning and repairs.
A steam generator constructed under my invention consists essentially of a
cylindrical or nearly cylindrical shell within which a furnace, a group of downtake
and a group of uptake fire or flue tubes are disposed in three sections substantially
as herein set forth.
The furnace is cylindrical or more advantageously in the form of the fustrum of
a cone, is placed excentrically within the shell and is provided at the top with a
dome, shaped so as to project sideways or horizontally from the furnace for about
one third of its circumference, from the underside of the projecting portion of the

a flue beneath the generator leading partly around the said generator, to a second

DESCRIPTION OF THE DRAWINGS.
Figs 1 and 2 are vertical sections at right angles, and fig 3 a horizontal section
of a steam generator constructed in accordance with my invention.
a is the shell within which is a furnace b of the form of a fustrum of a cone.
The said furnace is placed excentrically within the shell and is provided at the top
with a dome c shaped so as to project longitudinally at d into the water space;
from the underside of the said projection fire or flue tubes e lead through the water
space to the flue ƒ below. The flue f is carried partly round the said generator to
the group of fire or.flue tubes h, which pass through the water and steam spaces to
the smoke box i on the top of the generator and thence to the chimney.
Fig 4 is a vertical section, and fig 5 a horizontal section of a steam generator
under my invention in which the uptake fire or flue tubes instead of passing
directly upwards through the water and steam spaces to the top of thic generator
are curved so as to pass over the furnace and leave the generator at the side thus
being contained entirely in the water space.
Generators under my invention are made of plates and other portions formed bent
rivetted and connected by the usual means,

page_text: Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed I declare that what
I claim is
First. In vertical steam generators the combination of a shell, excentrically
placed furnace, projecting dome, downtake fire or flue tubes, bottom fluo and
uptake fire or Blue tubes leading to the chimney substantially as set forth.
Second. Vertical steam generators with a cylindrical or nearly cylindrical shell
in which a furnace and downtake and uptake flues or tubes are disposed in three
sections, substantially as herein set forth.
