Improvements in Apparatus for Separating Water Particles from
Steam.
I, WILLIAM LEWY, of Kralewska, Warsaw, in the Empire of Russia, Manu-
facturer, 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 improvements in apparatus for separating
water from steam, and is essentially characterised by the combination with such
apparatus of a steam blast jet, whereby water is prevented from rising in the
pipe (F) which projects into the boiler water by reason of joltings of the boiler,
such for instance as locomotive boilers are exposed to, and any penetration of the
water in the actual drying apparatus is excluded.
This improved apparatus is shown in the accompanying drawings, in which,
Figure I is an apparatus of the ordinary construction combined with a steam
blast jet;
Figure 2, an improved modification of the whole apparatus also in combination
with a steam blast jet, the latter being however merely shown in dotted lines;
Figure 3, a section on the line -b of Figure 2.
The steam from the boiler enters the apparatus in the direction of the arrows a
and strikes the plate or disc b which is carried by four pieces of plate iron c. From
the plate or disc b the steam whirls upward and passes in the direction of the
arrows & into the second plate or disc which is carried by two or more tubes g.
The steam here passes over the edge of the plate or disc in the direction of the
arrows i to the outlet tube or drying apparatus A.
The steam jet apparatus D is attached to a chamber H and the steam passes
into this jet apparatus through a nozzle J and is discharged in the direction of
the arrow through a pipe E, which in the present form of construction opens
between the upper and lower disc of the apparatus. In the steam drying appa-
ratus the steam enters in the ordinary manner from above, whilst the water
accumulates in the separate dish shaped discs and flows into the chamber or
box H through the pipe C. As the steam passing through the nozzle J produces
a vacuum between this nozzle J and the lower nozzle D', the water which
accumulates in the box or chamber H flows downwards through the nozzle D¹ and
returns through the pipe F into the boiler.
The steam flowing through the nozzle D' always exerts a certain pressure on
the tube F and prevents the boiler feed water penetrating in the same upwards
and entering the box H.
Figures 2 and 3 show a modified form of construction which differs from the
ordinary arrangements essentially in that the actual steam drying apparatus is
not provided with dish shaped discs but essentially consists only of a casing B
tapering towards the top, to which the steam jet apparatus is attached in any
suitable manner, the said jet apparatus being shown in Figure 2 only in dotted
lines. Steam enters the casing B through openings at the upper part. These

page_text: openings are formed by the wall at this spot consisting of separate oblique slats
or vanes y, as shown more particularly in Figure 3. The steam entering through
the openings is forced to move downwards in the tube B in a spiral. Owing to
the centrifugal force thus evolved the small separate water particles are thrown
outwards and are deposited on the floor of the vessel where they are conveyed
through openings into the steam jet apparatus.
Instead of the steam jet apparatus, an ordinary Korting injector may be
employed.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The improvement in apparatus for separating water particles from steam,
characterised by a steam jet apparatus or Korting's injector being inserted
between the water discharge pipe and the actual steam drying apparatus, with
the object of avoiding a rapid drawing off of the water from the steam jet appa-
ratus and simultaneously a rising of the water in the discharge pipe, substantially
as described and shown in the accompanying drawings.
2. In apparatus of the kind described, a modification of the steam drying
apparatus, characterised by the arrangement of openings a formed by obliquely
arranged slats or vanes y on the casing of the apparatus B with the object of
forcing the steam to move spirally downwards in the interior of the apparatus
and produce a separation of the particles of water in consequence of the centri-
fugal force, substantially as described and shown in the accompanying drawings.
Dated this 16th day of November 1897.
