for an Invention of "AN IMPROVED COMPOSITION FOR PREVENTING INCRUS-
TATION AND CORROSION IN STEAM BOILERS AND OTHER APPARATUS FOR
GENERATING STEAM AND FOR CLEANSING CONDENSERS
"
PROVISIONAL SPECIFICATION left by the said John Pover at the Office of
the Commissioners of Patents on the 6th February 1882.
"AN IMPROVED
STEAM
JonN POVER, of Liverpool, in the County of Lancaster.
COMPOSITION FOR PREVENTING INCRUSTATION AND CORROSION IN
BOILERS AND OTHER APPARATUS FOR GENERATING STEAM, AND FOR CLEANSING
CONDENSERS
My Invention relates to the manufacture of a non corrosive detergent for the
removal and prevention of incrustation in steam boilers, and is also applicable for
cleansing condensers.
The composition according to my Invention consists of the following materials
and liquids, mixed in, or about the proportions set forth.
One part of the best quality of soda ash, to which is added one part of the best
quality of soda crystals, to which is added one part of second quality of soda ash.
There is then added, one part of the best lime.
These ingredients are then boiled in
One part of fresh water, the lime assisting in the incorporation.
To this mixture (when cool) there is then added. One part of liquid zine.
The composition compounded according to the above formulae is used in such
proportions as inay be found necessary and applied through the feed water cisterns,
or by other means to the interior of steam boilers with the result that any
incrustation there may he is loosened and removed from the inside of the shell and
other parts of the boiler. The composition also counteracts any corrosive action
that may be taking place in the boiler and prevents the pitting that often takes
place inside boilers.
The composition is also applicable for the cleansing of foul surface condensers,
the use and action being similar to that described for steam boilers.

JOHN POVER, of Liverpool, in the County of Lancaster. "AN IMPROVED
COMPOSITION FOR PREVENTING INCRUSTATION AND CORROSION IN STEAM
BOILERS AND OTHER APPARATUS FOR GENERATING STEAM AND FOR CLEANSING
CONDENSERS
My Invention relates to the manufacture of a non corrosive detergent for tho
removal and prevention of incrustation in steam boilers and is also applicable for
cleansing condensers.
The composition being the non corrosive detergent according to my Invention
consists of the following materials and liquids mixed in, or about the proportions
herein set forth.
One part of the best quality of soda ash, to which is added one part of the
best quality of soda crystals, to which is added one part of second quality of soda
ash. There is then added one part of the best lime.
These ingredients are then boiled in
One part of fresh water, the lime assisting in the incorporation. All sediment
is then removed, and to this mixture, there is then added one part of zinc.
As_an_example_of putting my Invention into practice, I take
One part consisting of soda ash first quality, one part consisting of soda
crystals best quality, one part consisting of soda ash second quality. These three
are taken in equal proportions. For example having a combined total of 8 lbs.
in weight which is placed in a suitable vessel and is then dissolved in one part
consisting of say 20 lbs. of water and after being thoroughly dissolved is boiled
and when boiling there is added one part consisting of say 1 lb. quick lime.
The mixture is then allowed to cool and all sediment is then removed. The
clear liquid is again boiled and when boiling there is added one part consisting of,
say 1 lb. of zinc, preferably best rolled zinc, which is immersed in the boiling
liquid, the zine being kept in contact with a piece of iron, preferably polished iron,
dissolves into the liquid, and when the zinc is dissolved in the liquid, the liquid
may be cooled down and is then ready for use.
I would remark that in my Provisional Specification, I state that I use what is
known as "liquid zinc," applied to the liquid mixture when cold but I have since
found that it is better to obtain the "liquid zinc" by dissolving sheet zinc in the
boiling liquid as herein stated.
The composition compounded according to the above formulae is used in such
proportions, as may be found necessary and applied through the feed water
cisterns, or by other means to the interior of steam boilers with the result that
any incrustation there may be is loosened and removed from the inside of the shell
and other parts of the boiler. The composition also counteracts any corrosive
action that may be taking place in the boiler and prevents the pitting that often
takes place inside boilers.
The composition is also applicable for the cleansing of foul surface condensers,
the use and action being similar to that described for steam boilers.

A non corrosive detergent consisting of the composition composed of the
ingredients herein specified, compounded substantially as described.
In witness whereof, I, the said John Pover have hereunto set my hand and
seal this Third day of August, in the year of our Lord One thousand eight
hundred and eighty two
