Improvements in Steam Boilers.
ANDERS BORCH RECк Civil Engineer 155 Gothersgade Copenhagen Denmark
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to dry the steam from steam boilers, especially
from vertical boilers, before the steam leaves the boiler.
My invention consists of a horizontal diaphragm (of iron plate or like materia.
placed inside the boiler near its water line and closing as tight as possible to the
outer shell of the boiler and around such fire tubes as may pass from the fire box
to the top of the boiler. This said diaphragm shall be provided with holes,
forming passages for steam and water, and in each of these holes shall be fixed
one end of a tube, said tube having its other end free. One set A-A of these
tubes shall have their free ends upwards in the steam space of the boiler, the rest
of them, B-B, shall have their free ends downwards in the waterspace as close
to the bottom of the boiler as possible without interfering with the free passage
through the tubes. Over and around the upper ends of the tubes A-A may be
placed deflecting plates of varied forms.
When water is converted into steam in the boiler, a mixture of steam and water
will rise up through the tubes A-A. This mixture, in striking against the top
of the boiler or against the deflecting plates, placed over the tubes, will separate,
the steam leaving the boiler through the steam outlet in a dry state, the water
returning to the waterspace of the boiler through the tubes B-B.

Improvements in Steam Boilers.
I, ANDERS BORCH RECK, of Gothersgade 155, Copenhagen, in the Kingdom
of Denmark, Civil 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 object of this invention is to dry the steam from steam boilers, especially
from vertical boilers, before the steam leaves the said boiler.
My invention is illustrated in the accompanying drawing which shows a section
of a vertical boiler constructed according to my said invention.
My invention consists of a horizontal diaphragm d (of iron plate or like material)
placed inside the boiler near its water line and closing as tight as possible to the
outer shell of the boiler and around such fire tubes as may pass from the fire box
to the top of the boiler. The said diaphragm is provided with holes, forming
passages for steam and water, and in each of these holes is fixed one end of a tube,
said tube having its other end free. One set a of these tubes have their free ends
projecting upwards into the steam space of the boiler, while other tubes 6 bave
their free ends projecting downwards into the waterspace as close to the bottom of
the boiler as possible without interfering with the free passage through the tubes.

page_text: Over and around the upper ends of the tubes a may be placed deflecting plates
of any suitable form.
When water is converted into steam in the boiler, a mixture of steam and water
will rise up through the tubes a. This mixture, in striking against the top of the
boiler or against the deflecting plates c, placed over the tubes will separate, the
steam leaving the boiler through its steam outlet in a dry state, the water returning
to the waterspace of the boiler through the tubes b.
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 :-
An improvement in steam boilers consisting of a diaphragm inside the boiler
near its water line, this diaphragm being provided with holes in which are inserted
two sets of open tubes, one set having their free ends upwards in the steam space
of the boiler, and the other set having their free ends downwards in the waterspace of
the boiler, substantially as and for the purpose set forth.
Dated this 17th day of October 1895.
