AN IMPROVED
Agents, do hereby declare the nature of the said Invention for
METHOD OF CONCENTRATING THE SPENT LYE IN FIRELESS STEAM BOILERS" a com-
munication to me from abroad by Moritz Honigmann of Grevenberg, near Aachen,
in the Empire of Germany Soda Manufacturer through his agents, Wirth and
Company, of Frankfort on the Main, Germany to be as follows:-
The object of this Invention is to dispense with the use of fire for heating the
evaporating apparatus used in connection with fireless steam generation by means
of caustic soda or other solutions having a high boiling point whereby the soda
steam boiler will be of great use for mining and an economy can be effected in
large works where a surplus of steam exists.
It is known that force is stored in the soda steam boiler and that this force is
proportional to the quantity of evaporated soda lye.
This Invention relates to a method of evaporating again the caustic soda or other
solutions having a high boiling point by blowing steain into the water vessel of the
soda steam boiler.
When, after the working of the soda steam boiler, the soda has become spent by
the exhaust steam from the engine, a pipe leading into the water space of the soda
steam boiler is put in connection with a steam boiler and steam is blown into the
water space whereby the steam becomes condensed and the heat given out is
transmitted to the soda through the heating surface of the soda steam boiler; the
vapor from the soda lye is allowed to escape into the atmosphere until the boiling
point of the caustic soda lye is nearly equal to the temperature of the steam
blown in.

I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this Invention (a communication to me
from abroad by Moritz Honigmann of Grevenberg near Aachen, in the Empire of
Germany Soda Manufacturer through his agents Wirth and Company of Frankfort
on the Main Germany 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 dispense with the use of fire for heating the
evaporating apparatus used in connection with fireless steam generation by means
of caustic soda or other solutions having a high boiling point whereby the soda
steam boiler will be rendered of great use for mining and an economy can be
effected in large works where a surplus of steam exists.
It is known that force is stored in the soda steam boiler and that this force is
proportional to the quantity of soda lye evaporated.
This invention relates to a method of re concentrating the caustic soda or other
solutions having a high boiling point by blowing steam under pressure into the
water vessel of the soda steam boiler.
The accompanying drawing represents the general method of carrying the
invention into effect but it will be understood that the shape size and details of
construction of the apparatus can be varied.
When after the working of the soda steam boiler N the soda has become spent by
the exhaust steain introduced by pipe A from the engine D a pipe E leading into
the water space W of the soda steam boiler N is put in communication with a steam
boiler and steam under pressure is blown into the water space W whereby the
steam becomes condensed and the heat given out is transmitted to the soda through
the heating surface of the soda steam boiler N. The vapor from the soda lye is
allowed to escape into the atmosphere through the pipe F until the boiling point
of the caustic soda lye is nearly equal to the temperature of the steam under
pressure blown in.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
The herein described method of producing stored steam power by reconcentrating
the spent caustic soda or other solution having a high boiling point by means of
steam under pressure blown into the water vessel of a soda steam boiler as
specified.
