Feed Water for Steam Boilers.
I, ROBERT SHACKLETON, of the Borough Paper Mills, North Wing, Bradford, in
the County of York, Paper Manufacturer, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to certain improvements in the method of heating the feed
water for steam boilers, and has for its object, the raising of the temperature of such
feed water to a much higher degree than hitherto accomplished by methods in use,
thus facilitating the generation of steam.
I can accomplish iny object by three modes of proceedure; the first is by heating
the feed water taken from a cold supply, the hot well of an engine, or from an econo-
miser by hot air obtained in the following manner.
The air from the atmosphere is by means of an injector forced through a series of
pipes placed in the bottom flue of. a boiler or any other convenient chamber through
which the heated gases from the furnaces are passed. I send the feed water into a
chamber of suitable form baving wrought iron, copper, or other metal pipes therein,
through which the hot air is passed thereby heating the water surrounding the same,
or I pass the water through the pipes and surround the same with hot air.
Or I may accomplish my object, by boiling the water in a cistern fixed at an
elevation, the hot air obtained as before described being conducted thereto, and by
means of a feed pump, forcing the heated water into the boiler.
I may also accomplish my object by taking the feed water at the ordinary
temperature obtained by well known methods, and forcing the same through a series
of pipes as previously described, thereby raising the feed water before passing into the
boiler to a much higher temperature than hitherio, thus facilitating the generation of
steam.
Hitherto such water heaters have been supplied with steam for the purpose of
raising the temperature of the feed water, but in this my improvement I use hot air.

I, ROBERT SHACKLETON, of the Borough Paper Mills, North Wing, Bradford, in
the County of York, Paper Manufacturer, 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 relates to certain improvements in the method of and apparatus for
heating of feed water for steam boilers and analogous purposes in such a manner that,
the temperature of such water is raised more economically and to a higher degree
than by the ordinary methods now in common use, thereby facilitating the generation
of steam.
The invention consists in forcing atmospheric air by means of any well-known
agency, through a series of pipes placed in the bottom flue of a boiler or other
suitable heated chamber, through which heated gases from a furnace pass, thereby
heating the pipes, and consequently the air circulating through them to a high
temperature, which is conveyed by connecting pipes through another coil or series of
pipes placed in a vessel containing water, thus heating the same.
In the accompanying drawings,—Fig. 1. represents the front view of a boiler and
circular water heater, the bottom flue of the boiler and the water heater being in
section. Fig. 2. a plan of a boiler seating showing the position in which the pipes
may be placed in the said flue, the figure also representing a sectional plan of a water
heater; and Fig. 3. a section through a boiler furnace and bridge at the back thereof.
The atmospheric air may be forced into and through the coil of pipes A. by means
of an injector, rotary blower, fan or other known agency used for displacing air; the
pipes A. being placed in a heated chamber or flue of a steam boiler as at B. in the
position somewhat as shown by drawings, and are continuous so that, on air being
forced into and through the pipes A. by any of the before named agencies, it is heated
to a high temperature which I have found on testing to range from 500 to
600 degrees Fahrenheit: the pipes A. being connected to another coil or series of
pipes C. placed in a vessel D. of any convenient length and section.
The vessel D. is prepared with suitable jointed and true faced manholes E. similar
to those of a boiler; the interior of the vessel being provided with a range or coil of
pipes C. through which air heated as before described is forced, the exterior of the
pipes being by preference surrounded with water which is forced into the vessel
through a branch F. by an ordinary force or plunger pump: the water in the cistern
circulating through and amongst the range of pipes C. is considerably heated, and on

page_text: leaving the cistern by the branch G. at the opposite end may be conveyed to a boiler
through connecting pipe H.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is :-.
1. The combination of a series of pipes A. placed in a heated chamber, with a coil
of pipes C. enclosed within a cistern or vessel D. all being arranged substantially in
the manner as shown and described, for the purpose of heating feed water.
