Improvements in Apparatus for Separating Steam from Water and
Preventing Priming in Steam Generators.
I WILHELM LEWY Manufacturer, of Warschaw, Russia, do hereby declare the
nature of my said invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement:-
The object of the following invention is a apparatus for extracting the portion
or particle of 'water from the boiler caused by the development of the steam, and
is effected by means of the arrangement of a case or receptacle suitable for the
interior of the boiler, in which one or more plate shaped discs are arranged,
containing a centre waste pipe. The steam entering into the case or receptacle
is compelled to strike against the discs, whereby the particles of water contained
in the steam are extracted, as the same in striking are forcibly whirled up. By
means of the centrally arranged waste pipe, the extracted water flows back to the
water in the boiler, whilst the dry steam is conducted to its required position by
means of a suitable conductor.
In the accompanying drawing, the new arrangement is shown as follows:-
Figure 1 the steam extracting apparatus in sectional elevation, whilst.
Figure 2 part in plan, part in section in the line a b of Figure 1.
In the cylindrically formed case or receptacle is according to Figure 1, the
two plate shaped discs b and c are accommodated. The disc b consists of a conical
part to which the arched bow be applies. To the bow be is fastened the central
waste pipe d, which extends downwards in the disc c. The disc bis by means of
the lever piece e suspended in the case or receptacle. The steam entrance into
the case or receptacle is effected through the funnel shaped opening y in the
covering a. Below the disc b is shown the disc c, this consisting of the portion c¹
corresponding to portion 61 and bow c² corresponding to bow 68, and furthermore
of a certain waste pipe h. By means of the 4 waste pipes i, which extend down-
wards from the partitions k of the case or receptacle, the disc c is held in its
position. In the partition is shown another funnel shaped opening besides
the opening g. On the ground or base of the case or receptacle a rests the
cylinder portion m in which the pipe or tube h extends to the ground. On the
latter enclosed is fastened the waste pipe n, the length of which is so determined,
that a certain position extends into the water in the boiler. To the portion m,
furthermore, is attached the steam conducting pipes or tubes p, represented with
a flange r. The water conducting pipe or tube n furthermore carries a cap s at its
lower end which by the eventual sinking of the water level guards against all
escape so that the steam can enter into the pipe or tube.
The mode of operation of the whole apparatus is as follows:-
Through the inlet or opening 9 the steam enters the apparatus and strikes
against the plate formed arched bows 6 of the disc b is here whirled upwards
and drawn in the direction indicated by the arrow over the conical portion 61
away downwards. The particles of water hereupon becomes separated and flow
off through the central pipe downwards. The steam itself is forced downwards

page_text: partly through the tube i and partly through funnel shaped opening and comes
in contact with the bows c² of the discs c is here whirled upwards and travels in
the direction of ...e arrows over the conical portions el downwards whilst the
extractor water flows downwards through the tube h. The water from the tube d
as the same passes a narrow transverse cutting flows over into the tube h in order
to enter into the water in 'the boiler through the pipe n.
The steam which is now comparatively free from the molecules of water draws
off through the tube p.
Correspondingly is the whole apparatus so suspended in the boiler that the space
between e steam extracting pipe and the underneath water play is 500 mm.
The apparatus itself can receive a befittingly depressed form and can be applied
to any
desired boiler without fearing that the abatement of pressure can cause an
entering of 'water from below through the tube a.
The latter can, therefore, not enter because the pipes and n communicate
with one another the pressure on the water in the tubes n g is exactly the same
as the exterior, the water in the tube n enters into the case or receptacle if the
pressure is momentarily abated. is not in the position to reach high up in the
tube n.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
Apparatus for extracting particles of water from steam consisting of the
arrangement of one or more plate shaped discs bc with central waste pipes d and h
within a case or receptacle a into which the steam is conducted and by striking
against the discs is whirled upwards so that the particles of water are separated
from the same and flow back to the water in the boiler through the pipes d and h
whilst the dry steam can be conducted to the required position by means of the
conductor p.
