I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents.
Southampton Buildings, in the County of Middlesex, 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:-
The object of this invention, in general terms, is to produce a steam generator, in
which the steam is generated from heated or molton slag, or similar substances, by
bringing the water which is converted into steam into direct or immediate contact
with the heated or molten material; and my invention consists in the process and
apparatus hereinafter described.
In the accompanying drawing
Figure 1 is a plan of my improved steam generator.

chamber, shown at the lower portion of Figure 1.

yoke to enable such door to be tightly closed; F, an inner shell, which may be used
in the steam generating chamber to produce au annular water space between the
outer and inner shells; G, a lining which may also be used, if desired; H, a water
pipe or inlet; I, a steam pipe; J, the steam exhaust pipe from the steam receiving
and washing chamber.

page_text: As my invention consists in the process of utilizing heated or inolten slag to
generato steam from water brought into direct or immediate contact with it, the
various details of construction are of minor importance. A variety of steam tight
receptacles differing in form, location of paris, and means for introducing the heated
or molten slag, and removing the cooled slag, may be employed. I do not, therefore,
lay too much stress upon particular mechanical means for embodying and effectuating
my process; and while I shall describe and claim the apparatus illustrated in the
drawings, or, rather, the more substantial parts of it, I wish it to be distinctly
understood that I do not limit myself to more details of construction.
In the drawings, I have illustrated a pair of steam tight receptacles, preferably
cylindrical in formn, which I have lottered A and B, respectively. The chamber A is
intended for the generation of the steam, and may therefore be termed the steam
generating chamber. The chamber B is intended to receive the steam after it is
generated, and purify it from such impurities as are carried off with it from the heated
or molten material by which it is produced, and this chamber may be termed the
steam receiving and washing chamber. The steam generating chamber consists of a
steam tight shell, made of boiler iron, or other suitable material, with an opening
(preferably in the end, as shown), to admit a car or other receptacle containing heated
or molten slag, or similar material. As shown in the drawings, the steam generating
chamber is provided with a track or rails, and the slag car is provided with wheels or
rollers, so that it can be moved back and forth on the track.
The doorway or opening through which the molten slag is admitted, is arranged
and adapted to be closed, steam tight, when the molien slag has been introduced
into the generating chamber. I have shown one way of effecting this steam
tight closing, through means of a yoke and a screw and wheel, by which the door or
cover may be pressed tightly into place. The steam generating chamber is provided
with a water inlet or passage H, and a steam exhaust pipe or passage 1. The
passage I leads to the steam receiving and washing chamber B, which, as shown in
Figure 4, is partially filled with water, and the steam admitted into it beneath the
surface of the water, so that as it passes up through the water it becomes cleansed or
purified from any particles or other impurities that may have been carried along with
it from the steam generating chamber. After being thus purified or washed, it
passes
off through a steam exhaust pipe J, provided with proper valves, to the cylinder or
other place of use.
While I prefer to use this steam receiving and washing chamber, yet it is evident
that it may be dispensed with and the process embodied or carried on without it,
although I prefer, or recommend, its use. Whore it is used several steam gonerating
chambers may be used in connection with it, although I have shown but one in the
drawings; but it is obvious that the steam from other generating chambers could be
introduced into it, and washed or purified, and the steam conveyed to the place of use,
as above described.
If desired, the steam generating chamber may consist of double walls or shells, as
shown in the modification illustrated in Figure 2, so as to provide a water space
between the shells; and if, desired, still another shell or lining G may be used, made
of cast iron or other material. The water space between the shells A and F may he
kept constantly filled with water so as to prevent the undue radiation and loss of hout.
The object of the lining G is, of course, to protect the shell F from being injured or
destroyed by the intense heat to which it is subjected from the heated or molten slag,
or the steam generated by it.
In operation, I introduce a quantity of heated or molten slag, or other similar
material, into a steam generating chamber, which is then closed, to render it steam
tight, and a body of water or spray introduced into the steam generating chamber so
as to be converted into steam by direct or immediate contact with the healed material.
The steam thus generated is carried through the steam pipes, either directly or
through a receiving chamber, to the place of use. After the heated slag, or othor
material, has become cooled, so that it no longer produces or generates steam, the
door of the generating chambor may be opened and the car or receptacle containing

page_text: it run out or removed and the cooled slag dumped or conveyed away, after which
another batch of heated or molten slag may be run in and the operation repeated
indefinitely.
Having now particularly described and ascertained the nature of the said invon-
tion, and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :--
First. The process of generating steam, which consists in bringing water and heated
slag, or similar material, in contact in a steam tight receptacle, substantially as
described.
Second. A slag steam generator consisting of a chamber provided with suitable
water supply and steam exhaust pipes, in combination with a vessel adapted to receive
heated or molten materials, said vessel being constructed to be placed in said chamber
and means for closing the chamber, substantially as described.
Third. A slag steam generator consisting of a jacketed chamber provided with
suitable water supply and steam exhaust pipes, in combination with a vessel adapted
to receive heated or molten materials, said vessel being constructed to be placed in
said chamber and means for closing the chamber, substantially as described.
Fourth. A slag steam generator consisting of a chamber provided with rails on the
interior of the chamber, and with suitable water supply and steam exhaust pipes, and
means for closing the chamber, in combination with a wheeled vessel adapted to
receive heated or molten materials, and to be used in connection with the aforesaid
chamber in the generation of steam, substantially as described.
Fifth. The combination of a slag steam generator having one or more steam
generating chambers, and adapted to receive hot or molten material, and provided
with suitable water supply and steam exhaust pipes or passages, and means for closing
the said chamber, with a steam storage or receiving chamber, having a steam pipe or
passage communicating with the steam generating chamber, or chambers, whereby
the steam inay pass from the generating chambers to the storage or receiving chambor,
substantially as described.
Sixth. The combination of a slag steam generator having one or more chambers
wherein steam is generated by bringing water into direct contact with hot or molten
matorial, with a chamber containing water, and a steam passage from the steam
generating chamber, or chambers, whereby the steam may pass from the generating
chambers into the said chamber containing water, and in contact with the water,
whereby the steam may be washed or cleansed of its impurities, and its temperature
equalized, substantially as described.
Seventh. In a slag steam generator having a chamber wherein steam is generated
by bringing water in direct contact with hot or molten slag, and having water supply
and steam exhaust pipes or passages, a lining in the said chamber to protect the shell
or wall that forms the chamber and prevent it from being destroyed by the high
degree of heat of the slag, or the steam within substantially as described.
