Improvements in Apparatus for Purifying and Heating Water.
I, FRANK EDWARD JORDAN, of 15, George Street, Mansion House, London, E.C.,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention consists of improvements in apparatus for purifying and
heating water in which the impurities contained are deposited principally by
heating the water by means of live or exhaust steam, hot air or gases.
I use an outer shell preferably of cylindrical form closed by suitable ends.
Within this shell I place a series of any number of shallow saucers and domes
of circular or oblong shape at any distance from but preferably close to each
other, alternately or in any other relative position one below the other, or I
may use saucers only so placed one below the other. The domes are preferably
of smaller diameter than the saucers. The saucers and domes may be con-
structed of any suitable material but preferably are constructed of steel plate.
The saucers and domes may be supported in any suitable manner either on a
framing placed inside or attached to the shell, or they may be supported from
or on each other.
An
Below the bottommost saucer or dome I provide a water reservoir and I
maintain the level of the water in this reservoir at a suitable height below the
bottommost dome or saucer by means of a float operating a check valve regu-
lating the admission of the water to the apparatus. One end or cover of the
shell is bolted or attached to it by other suitable means the shell being provided
with a flange for this purpose. A water feed pipe enters at or near the top
of the apparatus above the first saucer or dome, as the case may be, and (if
it be a saucer) may pass below the level of the water so as to form a water
seal. A water delivery pipe is inserted at or near the bottom of the reservoir
and may pass above the level of the bottom plate of the apparatus and may be
provided with a cap to prevent the passage out of any scale or mud.
opening is provided for the steam (or other hot gases) to enter near the bottom
or at the end of the shell and above the level of the water in the reservoir
and another opening is provided at or near the top of the shell for the exit
of the same.
A blow off pipe is placed in a suitable position at the bottom
of the reservoir and an overflow pipe immediately above the water level.
water guage is provided to indicate the level of the water in the reservoir.
baffle or separator of any suitable design may be employed for eliminating oil
or grease from exhaust steam (where this heating medium is used) before it
enters the apparatus. The apparatus is supported on three or more suitable
legs provided with screw adjustment for levelling purposes.

The water to be purified and heated passes into the apparatus through the
water feed pipe and into the topmost saucer direct, where a saucer is placed in
this position, flows over its edge and along its under side until the centre is
reached where it meets a dome or another saucer as the case may be. Where
domes are used the water flows over them and drops from all around their
outer edges into the saucer beneath. The same action takes place down through-
out the series until the water reaches the reservoir, from whence it is drawn off
for use in a steam boiler or for other purposes required>

page_text: By continually presenting by these means a thin film of water in a dis-
turbed state to the action of the steam or other heating gases and by heating
the water in the shallow saucers the impurities are deposited on the domes, in
the saucers and on the under sides of the saucers.
I so construct my apparatus that the domes and saucers can be easily taken
out and the scale which has formed upon them removed.
Where live steam is used as the heating medium the apparatus works at
boiler pressure the steam enters at any suitable point above the water level
and the purified and heated water may pass by gravity to the boiler.
In cases where it may be desirable to add carbonate of soda or other chemical
to the water to be purified, such chemical can be added to the water before
it enters the apparatus in any suitable manner.
I may also use my system of domes and saucers or saucers only within steam
boilers for the purpose of inducing the precipitation upon and in them of solids
contained in the feed water.

Improvements in Apparatus for Purifying and Heating Water.
I, FRANK EDWARD JORDAN, of 15, George Street, Mansion House, London, E.C.,
in the County of London, Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
This invention consists of an improved apparatus for purifying and heating
water in which the impurities contained are deposited principally by heating
the water by means of live or exhaust steam hot air or other gases.
I use an outer shell preferably of cylindrical form closed by suitable ends,
containing a series of shallow saucers and domes of circular or oblong form,
preferably close to each other and arranged alternately saucer and dome one
below the other, or I may use saucers only placed one below the other. The
domes are preferably of smaller diameter than the saucers and constructed of
steel plate or other suitable material. They are supported on an independent
framing or I may attach them or certain of them to the containing shell,
supporting the intermediate domes and saucers from those so attached or I may
build up
the whole of the domes and saucers from the bottom and provide
suitable distance pieces to hold them in position relative to the shell and to
each other.
Below the lowest saucer I provide a water reservoir of suitable capacity
and in case of the apparatus being employed at atmospheric pressure I prefer
to regulate the height of the water in this reservoir by a float controlling the
admission of the water by means of a valve or in other suitable manner.
When the apparatus is worked at boiler pressure, the height of the water
therein is governed by gravity the heater being fixed in such position that the
water level in it and in the boiler are equal.
To allow of cleaning the apparatus I prefer to attach one end of the shell
by bolts and flanges or other suitable means and I arrange the feed pipe to
deliver the water into the top saucer or over the top dome, in the former case
prolonging the feed pipe below the level of the saucer so as to form a water
seal. The delivery pipe is taken from near the bottom of the apparatus at
a suitable distance below the water level and may be provided with a rose or
other suitable means of preventing flakes of scale or other foreign bodies
entering the pipe.

page_text: I provide a blow off cock at the bottom of the apparatus and a scum cock
at the water level as well as a water gauge.
The exhaust steam or hot gases enter the apparatus at the bottom, pass
upwards among the domes and saucers parting with their heat to the thin
film of water exposed and are conducted out of the apparatus at the top.
In the drawings Figure 1 is a section through the apparatus and Figure 2 an
elevation of the same. The water to be heated enters by the feed pipe A and
passes into the topmost saucer B, flows over its edge and along its under side
until it reaches the centre where it meets with a dome C of smaller diameter
than the saucer B and from thence drips into the second saucer D and in this
manner to the bottom of the series of domes and saucers till it reaches the
reservoir E and thence passes out by the pipe F having deposited the lime
and other impurities in the saucers B and upon the under sides of the same
and on the surface of the domes C and in the reservoir E.
The exhaust steam or other gases employed to heat the water enter the
apparatus by the pipe G, pass round and among the domes C and saucers B,
coming into contact with the water lying in and passing in a thin film over
the under surface of the saucers B. and upper surfaces of the domes C and
finally passes out by the pipe H.
I may cause the steam or other gases to pass in a spiral direction round the
shell I and edges of the saucers B and domes C by deflecting or baffle plates
bolted to or otherwise fixed to the shell I or cage J, supporting the series of
domes C and saucers B.
In order that the saucers B, and domes C may be accurately levelled to
prevent the falling water running unevenly or down one side only of the
saucers B and domes C.
I may support the whole of the saucers B and domes C in a cage J slung
from the upper part of the shell I, and resting on the levelling screws K, or
alternately from a special support provided for that purpose having a universal
joint from which the cage may hang and be thus automatically levelled, or I
may support the whole apparatus on three or more legs provided with levelling
screws in which case the domes C and saucers B may be supported in a suitable
cage resting on the bottom of the shell I.
The blow off pipe L and overflow pipe M may be in the positions shown
or arranged in any manner that may suit the particular case.
I so construct the apparatus that the domes C and saucers B may be easily
removed for the purpose of cleaning and removing scale or other deposit.
The float N and valve are for the purpose of regulating the water level
when the apparatus is worked at atmospheric pressure.
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:-
1. In a
water heater and purifier the use of a series of demes C and
saucers B. arranged alternately one above the other as shown, the domes C and
saucers B being of equal diameter respectively, in the manner and for the
purposes above described.
2. The mounting of the series of domes C and saucers B in a cage J, sus-
pended from the top of the shell I, or from a special support, for the purpose
of levelling or automatically levelling the domes C and saucers B, as and for
the purposes above described.
3. In a water heater and purifier the construction and arrangement shown
in the drawings, as and for the purposes above described.
