PROVISIONAL SPECIFICATION.
Improved Method of and Means for Purifying Feed Water for
Steam Generators and the like.
I, GUILLERMO ANTONIO FARINI of Dartmouth Lodge Perry Vale Forest
Hill in the County of Surrey, Gentleman do hereby declare the nature of this
invention to be as follows:-
My invention relates to an improved method of, and means for, extracting
impurities from feed water as supplied to steam generators and the like, and consists
in placing iron or other metallic filings or borings in a suitable chamber through
which the feed water passes before reaching the generator, also placing oyster shells
therein. The action is, that the acids contained in the oil carried through with the
feed water is caused to attack the finely divided iron, and thus become neutralised,
while the lime in the water is caused to deposit upon the oyster shells by
precipitation under the normal feed water temperature, becoming in time thickly
coated.
I also interpose sponges or other porous and absorbent substances so that the
greater part of the oil and other impurities may be absorbed prior to the passage
of the feed water through the tank or vessel aforesaid. These sponges or the like
may readily be cleaned by steaming, soaking in a hydrocarbon fluid or other means
and are thus rendered fit for use again.

COMPLETE SPECIFICATION.
Improved Method of and Means for Purifying Feed Water for
Steam Generators and the like.
I, GUILLERMO ANTONIO FARINI of Dartmouth Lodge Forest Hill, in the
County of Surrey, Gentleman, 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 :-
My invention relates to an improved apparatus for purifying feed water for
steam and other boilers, and has for its object the separation of the oils and fatty
acids, and also affording means for neutralizing the effect of any mineral substance
in solution which under other circumstances would attack the plates of the
boiler.
In order that my invention may be clearly understood, I have appended the
accompanying sheet of drawings, in which
Figure 1 is a sectional elevation of the device, and Figure 2 is a plan view
thereof, similar letters of reference being used to denote corresponding parts in both
views.
A vessel or chamber A, is provided with one or more diaphragms B, and an
outlet C and inlet D. The diaphragms B are preferably perforated alternately at
the lower and upper parts as shown, so that the water passing from D to C or
vice-versa may be caused to percolate through the iron borings E which are placed
in the spaces between the diaphragms B. Iron in any divided state that provides
a number of rough and sharp edges may be used, the action thereof being to cause
the salts or the like held in solution by the water, which otherwise would attack
to 07

page_text: the iron plates of the boiler, to become neutralized by passing through the mass
of divided iron. An upper chamber F is provided, which is divided from the lower
chamber or vessel A by means of a perforated diaphragm 1. A set cock G relieves
this chamber of air when in action and enables it to maintain a normal liquid level,
upon the surface of which the oily residues and fatty acids will collect and float, so
as to form as it were, a liquid stratum, which may be drawn off from time to time
by means of a cock or equivalent device H. I may use sponge, or any absorbent
material in combination with the divided iron and perforated diaphragms, and may
saturate said absorbent material with any chemical re-agent for the purpose of
neutralizing or precipitating any deleterious matter held in solution by the feed
water, or I may introduce solid reagents to effect the same purpose, the nature of
which, in any case depends upon the character of the water subjected to treatment
and ascertained by analysis.
In adapting the apparatus according to my invention to a steam boiler in con-
nection with a condensing steam engine, I place one such apparatus between the
inlet and the condenser, and the other between the hot well of the latter and the
boiler. But in ordinary cases of adaptation to any boiler or the like where it is
desired to prevent deterioration by corrosion, it is sufficient to place one or more
of said apparatuses between the inlet to the boiler and the feed injector or pump.
In the case of the use of a feed water heater one apparatus should be placed
between the supply and the heater, and another between said heater and the
boiler.
The principle of the action of the device is essentially in that the divided iron,
or iron borings are first attacked by the salts or the like in solution, which are
thus neutralized, and said divided iron may be removed from time to time as may
be required.
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 ;-
First. In a device for purifying feed water for steam and other boilers, the
combination of a vessel or chamber A, with perforated diaphragms B and packed
with iron in a finely divided state, substantially as herein described and shewn by
the drawings hereto appended.
Second. In a device for purifying feed water for steam and other boilers the
combination of an oil collecting vessel F with the iron packed vessel A described
and referred to in the preceding claim-substantially as and for the purposes herein
set forth and shewn by the appended drawings.
Third. In a device for purifying feed water for steam or other boilers the use of
sponges or other absorbent material, saturated with a chemical reagent, or solid
reagents suitable for the water under treatment, in combination with the chambers
or vessels A and F, referred to in the preceding claims, substantially as and for the
purposes herein set forth.
