Improvements in Apparatus for Introducing Substances into Steam
Boilers to Prevent Incrustation therein.
1, WILHELM VORBACH, of 57 Aeussere Weberstrasse Zittau /S, in the Empire of
Germany, Engineer, do hereby declare the nature of this invention to be as
follows:-
If a steam boiler is operated for a long time or continuously it is necessary to
introduce solvents into the same during the operation, in order to prevent incrustation.
The improved apparatus constructed according to this invention is designed to
enable the aforesaid object to be effected in a very simple manner.
This apparatus consists essentially of a closed receptacle which is provided with
several branch pipes. One of these branch pipes is arranged at the highest point of the
receptacle and can be closed by a cover which is pressed against the said branch pipe
through the medium of a screw held in a bridge-piece. On one side of the receptacle,
in or near the middle of the same is provided a second branch pipe. An opening is
formed in the wall. of the receptacle, at the same height as the lateral branch pipe, so
that a bent pipe having a flange can be inserted, which pipe extends almost to the
bottom of the receptacle. Together with the flange on the bent pipe, a connecting
pipe is secured to the receptacle. In proximity to the bottom of the latter is arranged
a discharge cock.
The receptacle is included in the feed pipe by joining the said lateral branch pipe to
the feed apparatus and the above mentioned connecting pipe to the boiler.
Prior to setting the feed apparatus in operation the above mentioned solvent must
be introduced into the receptacle.
On setting the feed pump in operation the feed water passing through the said
receptacle will carry with it the solvent of incrustation and convey the same to the
boiler.
By removing the cover from the upper branch pipe after discontinuing the feed the
substances for preventing incrustation in the boiler can at any time be added in
the most convenient manner.
As the bent pipe leading to the boiler extends near to the bottom of the receptacle
the feed water will come in contact with the solvent and completely dissolve the same.

Improvements in Apparatus for Introducing Substances into Steam
Boilers to Prevent Incrustation therein.
I, WILHELM VORBACH, of 57 Aeussere Weberstrasse Zittau S in the Empire of
Germany, 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 :-
If a steam boiler is worked for a long time or continuously it is necessary to
introduce solvents into the same during the operation, in order to prevent incrustation..
The improved apparatus constructed according to this invention is designed to
enable the aforesaid object to be effected in a very simple manner.
The said apparatus is represented in section in the accompanying drawing.
The apparatus consists essentially of a closed receptacle A which is provided with
several branch-pipes. One of these branch-pipes 6 is arranged at the highest point of

page_text: the receptacle and can be closed by a cover d which is pressed against the said branch
pipe through the medium of a screw held in a bridge-piece e. On one side of the
receptacle, in or near the middle of the same is provided a second branch pipe e. An
opening is formed in the wall of the receptacle at the same height as the branch
pipe e so that a bent pipe having a flange g can be inserted which pipe extends
almost to the bottom of the receptacle.
Together with the flange g on the bent pipe a connecting pipe i is secured to the
receptacle. In proximity to the bottom of is arranged a discharge cock k.
The receptacle is included in the feed pipe by joining the said branch pipe e
feed apparatus and the above mentioned connecting pipe i to the boiler.
thie
Prior to setting the feed apparatus in operation the above mentioned solvent must
be introduced into the receptacle.
On setting the feed pump in operation the feed water passing through the said
receptacle will carry with it the solvent of incrustation and convey the same to the
boiler.
By removing the cover d from the upper branch pipe after discontinuing the feed
the substances for preventing incrustation in the boiler can at any time be added in
.the most convenient manner.
As the bent pipe h leading to the boiler extends near to the bottom of the receptacle,
the feed water will come in contact with the solvent and completely dissolve the same.
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 :-
A receptacle A provided with a cover d branch pipes e and discharge cock k and
included in the feed pipe, in which receptacle a pipe extending down close to the
bottom of the same is joined to the pipe i leading to the boiler, for the purpose of
introducing solvents of incrustation into steam boilers during their operation.
