PROVISIONAL SPECIFICATION.
Improvements relating to Steam Generators.
I, CARL PATAKY, of 100 Prinzen-strasse, Berlin, in the Empire of Germany,
Engineer, do hereby declare the nature of this invention to be as follows:-
The device hereinafter described serves to increase, in steam generators, the
surface of the steam and water mixture discharged into the steam space, for the
purpose of more efficiently separating the steam bubbles and thereby generating
dry steam.
For example in a water-tube-boiler, the tubular connection between the steam
drum and the headers, through which the circulating water (steam and water
mixture) ascends is provided with a device constructed from corrugated sheet
metal so as to present in section a mesh-shaped structure.
The upper extremity of the said device extends into the steam space and is
preferably gable shaped, in order that the circulating water rising in the cells of
the device may at its exit pass over into the steam space in jets as widely
distributed as possible. By thus separating the circulating current into many
separate jets which are discharged into the steam space in a spray, the free surface
of the circulating water is enormously increased, and the separation of steam
bubbles from the water is materially favoured and thus a dry steam is
obtained.
At the lower extremity of the aforesaid device metal pieces may slightly project
in such a manner that partitions are formed, the object of which is to divide the
entering steam bubbles and to convey them toward the different meshes of the
device so that the steam and water mixture may ascend in the cells as uniformly
as possible.

I, CARL PATAKY, of 100 Prinzen-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 :-
The device hereinafter described serves to increase, in steam generators, the
superficial content of the steam and water mixture discharged into the steam
space, for the purpose of more efficiently separating the steam bubbles and thereby
generating dry steam.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice, the figures being hereinafter
referred to.

page_text: In Figures 1 and 2 representing as an example a water-tube-boiler, a is a tubular
connection between the steam drum b and the headers c, through which the
circulating water (steam and water mixture) ascends. The tubular connection a
is provided with a device d constructed from corrugated sheet metal so as to
present in section a mesh-shaped structure. (See Figures 3 and 4.)
The upper extremity of the said device extends into the steam space and is
preferably gable shaped in order that the circulating water rising in the cells of
the device may at its exit pass over into the steam space in jets as widely distributed
as possible. By thus separating the circulating current into many separate jets
which are discharged into the steam space in a spray, the free surface of the
circulating water is continuously increased, and the separation of steain bubbles
from the water is materially favoured and thus a dry steam is obtained.
At the lower extremity of the aforesaid device metal pieces may slightly project
in such a manner that partitions are formed, the object of which is to divide the
entering steam bubbles and to convey them toward the different meshes of the
device, so that the steam and water mixture may ascend in the cells as uniformly
as possible.
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 :-
For the purpose of increasing the steam-generating surface and of thus obtaining
a dry steam in steam generators, the constructional arrangement, according to
which the rising portion of the circulating current (of the steam and water mixture)
is divided by an inserted device formed by corrugated sheet metal pieces which are
so joined together, that this said device presents a mesh-shaped cross-section, whilst
that extremity of the inserted device which projects into the steam space, is made
gable-shaped, in order to facilitate the separation of the sprays of circulating water
discharged from each of the cells and the lower extremity may or may not be
provided with partitioned spaces formed by extending a suitable number of sheet
metal pieces for the purpose of distributing the steam bubbles and of uniformly
conveying the steam and water mixture into the cells.
