AN IMPROVED WATER HEATER AND PURIFIER
Year: 1884

page_text: I THOMAS SYKES of 25 Milton Street Stockport Road Manchester in the County
of Lancaster Engineer do hereby declare the nature of my invention for AN
IMPROVED WATER HEATER AND PURIFIER to be as follows:-
The object of my invention is the utilization of the waste heated gases from
steam boilers or furnaces for the purification of water by which purification
I render the said water practically free from impurities usually found therein, such
impurities consisting firstly in those held by the water in chemical combination or
solution such as for instance carbonate of lime and of magnesia sulphide of lime
and chloride of sodium and secondly in, those held by the water in mechanical
suspension such as for instance clay sand and the like. For the above purpose
"fuel
I employ a series of pipes similar in construction to those known as
economisers" which pipes are heated by the waste gases from a steam boiler or
steam boilers, furnace or furnaces-The water to be purified I supply to a portion
of the pipes aforesaid by a cistern provided with a ball-cock or tap or valve by
means of which the water in such cistern and pipes aforesaid is maintained at an
uniform level. The water above referred to in its passage through the pipes above
named will become heated and by being so hented the greater part of the carbonic
acid gas contained by the aforesaid water will be liberated and will be allowed to
escape by means of a suitable opening or openings or pipe or pipes-The water
aforesaid after being rendered practically free from carbonic acid gas is forced by
means of a pump or other suitable apparatus through a further series of the pipes
above referred to and in its passage through such series of pipes the said water is
heated to a still higher temperature and the impurities held in chemical solution or
combination by the said water are in a great measure precipitated separated or
eliminated therefrom by this further heating-The impurities held by the water
aforesaid in mechanical suspension and the impurities previously held by such
water in chemical combination or solution and now precipitated separated or.
eliminated therefrom by the beating aforesaid are allowed to subside or separate
from the said water into chambers provided for the purpose of receiving the said
impurities, and from which chambers the impurities deposited therein may be
removed by a blow off cock or tap or other suitable means-The purified water
from the pipes above referred to may either pass into the steam boiler or steam
boilers previously mentioned or may be used for any other purpose or purposes to
which it may be suitable.

IMPROVED WATER HEATER AND PURIFIER 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 my invention is the utilization of the heat of the waste heated

cation I render the said water practically free from the impurities usually found
therein such impurities consisting firstly in those held by the water in chemical.
combination or solution such as for instance carbonate of lime and of magnesia
sulphate of lime and chloride of sodium and secondly in those held by the water in
mechanical suspension such as for instance clay sand and the like. For the above
purpose I employ a series of pipes similar in construction to those known as fuel
economisers which pipes are heated by the waste heated gases from a steam boiler
or steam boilers, furnace or furnaces The water to be purified I supply to a
portion of the pipes aforesaid by a cistern provided with a ball cock or tap or valve
by means of which the water in such cistern and pipes aforesaid is maintained at
an uniform level. The water above referred to in its passage through the pipes
above named will become heated and by such heating the greater part of the
carbonic acid gas contained by the aforesaid water will be liberated and will be
allowed to escape by means of a suitable opening or openings or pipe or pipes-The
water aforesaid after being rendered practically free from carbonic acid gas is
forced by means of a pump or other suitable apparatus through a further series of
the pipes above referred to and in its passage through such series of pipes the said
water is heated to a still higher temperature and the impurities held in chemical
solution or combination by the said water are in a great measure precipitated
separated or eliminated therefrom by this further heating-The impurities held by
the water aforesaid in nechanical suspension and the impurities previously held by
such water in chemical combination or solution and now precipitated separated or
eliminated therefrom by the heating aforesaid are allowed to subside or separate
from the said water into chambers provided for the purpose of receiving the said
impurities and from which chambers the impurities deposited therein may be
removed by a blow off tap or other suitable means. The purified water from the
pipes above referred to may either pass into the steam boiler or steam boilers
previously mentioned or may be used for any other purpose or purposes for which
it may be suitable.
In order that my invention may be thoroughly understood and readily carried
into effect I hereunto annex a drawing showing one method of carrying my
invention into practical effect-Fig. 1. is a side elevation partly in section of an
apparatus by means of which my invention may be readily carried into practical
etct Fig. 2. is a plan partly in section of Fig. 1. and Fig. 3. is an end view of a
portion of Fig. 1-At a. are pipes similar in construction to those used in the
apparatus known as fuel economisers-The pipes a. communicate at their upper

page_text: ends with the chambers or boxes b.-The chambers or boxes b. are in communi-
cation with each other by means of the pipe c. and pipes d.-The lower ends of the
pipes a. communicate with the chambers or boxes e. and the chambers or boxes e.
communicate with the pipe f. by means of the pipes g.-The pipe f. communicates
by means of the pipe h. with a cistern k. Water is supplied to the cistern k. by
means of the pipe L. and the level of the water within the cistern k. is maintained
at about the level indicated by the line A B. by means of the ball m. and cock,
tap or valve n. At o. are more vertical pipes which pipes o. communicate at their.
upper ends with boxes p. which boxes p. are connected by pipes q. to a pipe .—
The lower ends of the pipes o. are in communication with boxes 8. which boxes s.
cominunicate by means of the pipes t. with the pipe u. The pipes a. o. are situate
between the walls C C of and within a flue C. along which flue C. pass the wasto
heated gases from a steam boiler or boilers or from a furnace or furnaces by which
waste heated gases the water passing through the pipes a. o. as will be hereinafter
described is lieated.
The water from the cistern k. flows along the pipes h f. g. into the boxes e. and
from the boxes e. into the pipes a. and while passing through the pipes a. becomes
heated by the waste heated gases from the steam boiler or boilers or from the
furnace or furnaces aforesaid which waste heated gases flow past the pipes a. in
the direction of the arrow D. The interiors of the boxes b. communicate with the
atmosphere by means of pipes z. which pipes x. are open at their upper ends to the
atmosphere.
Upon the water in the pipes a. becoming heated the greater part of the carbonic
acid gas contined in the aforesaid water will be liberated therefrom and will escape
through the pipes x. into the atmosphere-The water aforesaid after being in a
great measure deprived of the carbonic acid gas previously contained therein passes
along the pipes d. c. to a pump or other suitable apparatus by which it is forced
along the pipes u. t. into the boxes 8. and thence through the pipes o. into the
boxes p-The water above referred to in its passage through the pipes o. will
become highly heated by the heated gases flowing past the pipes o. in the direction
of the arrow D. The water in the pipes o. will be heated ther-in to a temperature
much higher than that to which the said water was heated within the pipes a. and
the greater part of the impurities held by the said water in chemical combination
or solution will be precipitated separated or eliminated from the water aforesaid by
this further heating-The impurities held by the water aforesaid in mechanical
suspension and the impurities previously held by such water in chemical com-
bination or solution and now precipitated separated or eliminated therefrom by
the heating aforesaid will subside or separate from the said water into the boxes or
chambers 8. from which boxes or chambers s. the impurities above referred to may
be removed by the pipes y. 2. and blow off tap or cock 1 or any other suitable
means The boxes or chambers e. communicate by means of pipes 2, 3 with a blow
off cock or tap 4 or other suitable apparatus by which any impurities precipitated
separated or eliminated from the water passing through the pipes a. and deposited
The heated and purified
in the boxes or chambera e. may be removed therefrom
water from the pipes o. may either pass into the steam boiler or steam boilers
previously mentioned or may used for any other purpose or purposes to which such
water may be suitable.
The apparatus herein before described may if requisite be provided with scrapers
or any other suitable apparatus actuated in any convenient and suitable manner by
which scrapers or other suitable apparatus the pipes a. o. above referred to may be
kept free from soot or other matter deposited upon such pipes a. o. by the waste
heated gases aforesaid.
I would have it understood that I do not confine myself to the precise method
and apparatus herein before described as such method and apparatus may be varied
without departure from the principle of my Invention-For instance the pipes' a. o
may be placed in an inclined or horizontal position instead of being placed as

page_text: shown in the drawing hereunto annexed in a vertical position or the pipes a o
may be employed in larger or smaller numbers than are shown in the said drawing.
By the Invention herein before described I cause the impurities contained in the
water passing through the apparatus hereinbefore described to be precipitated or
deposited in the boxes or chambers 8.
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
Firstly. The utilization of the heat of the waste heated gases from a steam boiler
or steam boilers or furnace or furnaces for heating and purifying water substantially
as bereinbefore described.
Secondly The method substantially as herein before described of heating and
purifying water by means of the waste heated gases from a steam boiler or steam
boilers or furnace or furnaces which method consists in first heating the water
aforesaid in pipes open at one end to the atmosphere and afterwards further heating
the said water in closed pipes substantially as herein before described.
Thirdly The herein before described apparatus constructed arranged and operating
substantially as hereinbefore described in reference to the drawing hereunto annexed
for heating and purifying water by means of the heat of the waste heated gases
from a steam boiler or steam boilers or furnace or furnaces.
