I, JAN VON BISKUPSKI, Engineer of No. 6 Bielanska Street, Warsaw in the Empire
of Russia, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved steam drying apparatus, and has for its
object to effectually dry steam on issuing from the boiler, and to effectually
abstract all moisture therefrom.
My invention consists in means for producing a centrifugal action of the steam
so that it may be caused to impinge upon a surface or surfaces by which moisture
contained therein may be deposited, and the lighter dry steam caused to pass
through the steam outlet.
In the adaptation of my invention to a locomotive boiler I mount a separating
chamber within the steam dome which separating chamber I preferably provide
of a truncate conical form, having its interior sides tapering outwardly from above.
From the upper surface or plate of this truncate conical separating chamber I
provide a series of curved plates, annularly disposed and projecting inwardly about
the inlet aperture into the chamber, so that as the steam enters it is guided in a
circular lateral direction, and a centrifugal action is imparted thereto by which
particles of steam are forced against the conical sides of the chamber, and the
deposition of the water particles is effected, while the dry steam, being of less
specific gravity, takes a central course, and issues out of the separating chamber
through a projecting tube to the valve chamber disposed immediately thereunder.
This connecting pipe or tube has provided at its extremity a flaring flange down-
wardly projecting towards the sides of the separating chamber, so that the water
particles as they may be deposited thereupon may flow down to the lower surface
of the separating chamber, which is preferably formed spirally, so that the water
deposited thereon may in turn flow to the lowest level of the spiral surface, where
a downwardly projecting pipe is provided in communication with the water
in the boiler by which the deposited water is returned. This downwardly
projecting pipe is in free communication with the water of the boiler, but has
provided at its extremity a cap or cage which prevents the convection of the boiler
water being freely communicated to the water that may be in its lower extremity
of the connecting pipe.
The outwardly flaring flange provided upon the connecting tube which projects
within the separating chamber has provided thereunder a vertically disposed wall
or tube whose lower circular edge is in contiguity or provided integral with the
lower spiral surface of the chamber.
A series of apertures are provided around the flaring flange at its upper part, so
that the water deposited upon that part may pass through into the space defined

page_text: by the vertical wall or tube, and may pass to the lowest level where the upper
aperture of the tube issues.

An improved Steam
rying or separating Apparatus.
1, JAN VON BISKUPSKI, of No. 6, Bielanska Street, Warsaw, in the Empire of
Russia, and of No. 1, Neue Wilhelm Strasse, Berlin, in the Empire of Germany,
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:-
My invention relates to an improved steam drying apparatus, and has for its
object to effectually dry steam on issuing from the boiler, and to effectually extract
all moisture therefrom.
My invention consists in means for producing a centrifugal action of the steam,
so that it may be caused to impinge upon a surface or surfaces by which moisture
contained therein may be deposited, and the lighter dry steam caused to pass
through the steam outlet.
My invention is illustrated in the accompanying drawings, wherein
Figure 1 represents a side elevation of one arrangement of the apparatus, while
Figure 2 is a vertical section corresponding to Figure 1, and
Figure 3 is a plan corresponding to Figure 2, and
Figure 4 is a sectional plan on the line R S Figure 2, and
Figure 5 is an elevation showing the apparatus in position in the steam dome of
a locomotive boiler.
In carrying my invention into effect as illustrated in the accompanying drawi
ings, and as adapted to a locomotive boiler I mount a separating chamber A
within the steam dome which separating chamber A I preferably provide of a
truncate conical form, having its interior sides tapering outwardly from above.
From the upper surface or plate B of this truncate conical separating chamber A
I provide a series of curved plates C annularly disposed, and projecting inwardly
about the inlet aperture into the chamber, so that as the steam enters through B
it is guided in a circular lateral direction, and a centrifugal action is imparted
thereto by which particles of steam are forced against the conical sides of the
chamber A, and the deposition of watery particles is effected, while the dry steam,
being of a less specific gravity, takes a central course and issues out of the
separating chamber through a projecting tube F to the valve chamber L disposed
immediately thereunder. A cone C is provided upon the bottom plate of the
vanes C, for directing the steam towards the vanes, while a further circular pro-
jecting surface C is provided for the purpose of guiding the steam in the circular
movement imparted to it in virtue of the direction of the vanes.
This connecting
pipe or tube F had provided at its extremity a flaring flange o, downwardly
projecting towards the sides of the separating chamber A, so that the water
particles as they are deposited thereupon may flow down to the lower surface p
of the separating chamber, which is preferably formed spirally, so that the water
deposited thereou may in turn flow to the lowest level D of the spiral surface,

page_text: where a downwardly projecting tube E is provided in communication with the
water in the boiler, by which the deposited water is returned. This downwardly
projecting tube E is in free communication
E is in free communication with the water of the
boiler but has provided at its extremity a cap or cage H secured
to the extremity of the tube E by means of strips or holders a,
such cap or cage preventing the convection of the boiler water being freely com-
municated to the water which may be in the lower part of the connecting tube E,
and preventing steam bubbles rising up from boiling water, and passing up
through the tube. The outwardly flaring flange o provided upon the connecting
tube which projects out of the separating chamber A has provided thereunder a
vertically disposed wall or tube N whose lower circular edge is in contiguity or
provided integral with the lower spiral surface p of the chamber. A series of
apertures K are provided around the flaring flange o at its upper part, so that the
water deposited upon that part may pass through into the space defiued by the
vertical wall or tube, and may pass to the lowest level, from which the upper
aperture of the connecting tube E issues.
Having now particularly described and
invention, and in what manner the same is
I claim is:
ascertained the nature of my said
to be performed, I declare that what
1. An apparatus for separating the water particles from steam characterised by
the fact that a rotary motion is imparted to the steam by means of a series of fixed
vanes provided within a chamber, the water particles conveyed by the steam being
caused by the centrifugal action occasioned in its passage through the vanes to
be deposited along the wall of the chamber falling down through a tube opening
into the boiler water, while the dry steam passes off for consumption, substantially
as described.
2. In an apparatus such as specified in the first claim, the arrangement of a cap
or cage H at the lower extremity of the tube E which serves to convey the separated
water from the chamber A. into the boiler, said cap or cage projecting beyond the
lower edge of the tube E for the purpose substantially as herein before described.
3. In an apparatus such as that specified in the first claim a separating
chamber A provided with a flaring flange, such as o, having holes or apertures
therein, and a vertical circular wall such as N which forms an annular space about
the communicating tube, such as F, the communicating tube such as E, being in
communication with such annular space and with the chamber A, substantially
as and for the purpose hereinbefore described.
4. In an apparatus such as that specified in the first claim the arrangement of
vanes C with a cone C and a projecting surface Cas and for the purpose here-
inbefore described, and as illustrated.
5. An improved steam drying apparatus substantially as and for the purpose
here illustrated.
