Water Distiller, Feed-water Purifier and Make-up Apparatus for Hot
Water and Steam Supply and Warming Installations:
I, WILLIAM MURRAY BINNY, Consulting Engineer, 53, Victoria Street, West-
minster, London, S.W., do hereby declare the nature of this invention to be as
follows:-
My invention relates to an apparatus for the supply of pure distilled water for
feeding boilers in connection with hot water and steam supply and warming
installations. It may also be used to provide pure distilled water for heating
pipes or for hot water supply in hotels, laundries, and 'the like.
The apparatus consists of a steam boiler, a steam coil evaporator, a steam coil
heater, hot water supply or circulating pipes, either of which may be in duplicate
or multiple, and the necessary pumps, valves and subsidiary apparatus.
The impure water from the natural source of supply necessary to make up for
the steam or water drawn off from the system is led into the evaporator where
it is converted into steam by means of the boiler steam circulating inside the
evaporator coils, leaving all the impurities deposited in the evaporator. The steam
condensed in the evaporator coils is led to the automatic boiler feed pump and
again returned to the boiler. The steam generated in the evaporator is led to the
heater where it heats the water in the hot water circulation pipes; the heater
thus acting as a condenser for the make-up supply. The steam condensed in the
heater is led to the boiler feed pump and is returned to the boiler as pure supple-
mentary feed water; being previously heated if desired by steam from the
evaporator or by live steam from the boiler.
When no steam or water is being drawn off from the system, the steam required
for warming purposes passes direct from the boiler to the heater; a reducing
valve being employed if necessary. A non-return valve on the steam pipe between
the evaporator and the heater then prevents the boiler steam flowing backwards
into the evaporator. A stop valve on the steam supply pipe to the evaporator
coils can be shut down when no make-up feed-water is required.
The apparatus can be adapted for the supply of pure hot water for washing or
manufacturing purposes. The hot water supply in such cases may be taken
either from the condensed steam drained from the evaporator or from the heater.
In the latter case, a force pump may be used if necessary and the water further
heated by steam either from the evaporator or from the boiler. The warming
ipes in connection with the heater may be used in drying rooms or for warming
buildings.
"
In using the above apparatus, in any of its forms, the impurities in the natural
vater supply are deposited in the evaporator, from which they can be easily
emoved in the usual way as occasion demands.

Water and Steam Supply and Warming Installations.
I, WILLIAM MURRAY BINNY, Consulting Engineer, 53, Victoria Street, West-
minster, London, S.W., do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and as-
certained in and by the following statement:
My invention relates to an apparatus for the supply of pure distilled water, for
feeding boilers in connection with hot-water and steam supply and warming
installations. It may also be used to provide pure distilled water for heating
pipes or for hot-water supply in hotels, laundries, and the like.
The apparatus consists of a steam boiler, a steam coil evaporator, hot-water
supply or circulating pipes, either of which may be in duplicate or multiple, and
the necessary pumps, valves and subsidiary apparatus.
Figure 1 shows diagramatically the arrangement of the apparatus.
The impure water from the natural source of supply necessary to make up for the
steam or water drawn off from the system is led into the evaporator E (a feed-
pump being used if necessary) where it is converted into steam by means of the
boiler steam circulating inside the evaporator coils, leaving all the impurities
deposited in the evaporator. The water condensed in the evaporator coils is led
by the pipe P₁ to the automatic boiler feed-pump P and again returned to the
boiler B. The steam generated in the evaporator is led by the pipe P, to the
heater H where it heats the water in the hot-water circulation pipes; the heated
water leaving the heater by the flow pipe F, and the cooled water returning to
the heater by the return pipe R; the heater thus acting as a condenser for the
make-up supply. The steam condensed in the heater is led by the pipes P, to the
boiler feed-pump and is returned to the boiler as pure supplementary feed-water;
being previously heated if desired by steam from the evaporator or by live steam
from the boiler.
ون
When no steam or water is being drawn off from the system, the steam
required for warming purposes passes direct from the boiler to the heater by the
pipes P, P, P; a reducing valve re being employed if necessary. A non-return
valve nr on the steam pipe between the evaporator and the heater then prevents
the boiler steam flowing backwards into the evaporator E. A stop valve s von
the steam-supply pipe to the evaporator coils can be shut down when no make-up
feed-water is required.
The apparatus can be adopted for the supply of pure hot water for washing
or manufacturing purposes. The hot-water supply pipe H W S in such cases may
be taken either from the condensed steam drained from the evaporator or from
the heater. In the latter case, a force pump may be used if necessary and the
water further heated by steam either from the evaporator or from the boiler.
The warming pipes in connection with the heater may be used in drying rooms
or for warming buildings.
In using the above apparatus in any of its forms, the impurities in the natural
water supply are deposited in the evaporator, from which they can be easily
removed in the usual way as occasion demands; a moveable door being provided
for this pupose.
Having now particularly described and ascertained the nature of my said in-
vention, and in what maner the same is to be performed, I declare that what I
claim is:-
1. In an apparatus for the production of pure distilled water, the combination

page_text: of a steam coil heater of a hot-water heating system, a boiler or evaporator in
which the water is distilled, and the necessary pipes and connections; the said
steam heater acting as a condenser for the distilled water.
2. In a make-up apparatus for a steam boiler, the combination of a steam coil
evaporator in which the natural water supply is evaporated by the steam from the
main boilers, a steam coil heater of a hot-water heating system acting as a con-
lenser for the distilled water, and of two drain pipes leading from the coils of
the said steam coil evaporator and heater respectively to the feed-pump of the
boiler.
3. In a steam supply and warming installation, the combination of a steam
boiler, a steam coil evaporator, and a steam coil heater, for the supply of pure
hot water for the boiler or for other purposes; substantially as described and
illustrated in Figure 1.
