COMPLETE SPECIFICATION.
Apparatus for Quenching Coke.
1,,THOMAS REHRER OSBOURN, a citizen of the United States, residing at.
1207 Spruce Street, in the City of Philadelphia, County of Philadelphia, State of
Pennsylvania, United States of America, Engineer, 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 :-
Expressed in general terms my invention comprehends the provision of a suitable
receptacle, chamber, vessel, or receiving case, be its form, proportions, or
dimensions, what they may, which is adapted to receive the charge of coke to be
quenched, or extinguished, and which is wholly or in part double walled, jacketed,
or encased, or so otherwise provided with a water chamber to contain water, that
when the charge is introduced into the said receptacle its action of heat radiation
to and upon the water in the water chamber or compartment will be such as to
convert the water into steam and occasion the influx of such steam into the coke
containing receptacle through such suitable apertures, orifices, pipes, or injectors,
as may be necessary to place the steam generating compartment in communication
with the coke-containing compartment..
Obviously the mechanical embodiment of my invention may be varied and I do
not restrict myself to any special form or construction of it, although, in practice,
such an apparatus as is represented in the accompanying drawings and hereinafter
described conveniently embodies my invention.
In the drawings, of which Figure 1 is a rear elevation and Figure 2 a transverse
sectional elevation on the line X X of Figure 1,-of an apparatus conveniently
embodying my invention,-A represents the coke-containing compartment of the
receptacle. B is the water containing compartment or jacket, in which the water
is placed and the steam generated by the action of the hot coke in the com-
partment A, and from which the steam is discharged into said compartment A,
conveniently through the spraying pipes C, which are simply an ordinary
form of steam pipe placed in either compartment and communicating with both
compartments L.
In the construction represented a series of these pipes C is employed, and the
pipes are provided with a series of spraying orifices or small holes which face and
lischarge into the coke-containing compartment, while the inlet ends of the pipes
open within the water compartment.
In the arrangement represented in the drawings, moreover, the water coin-
partiment is subdivided by partitions to form a series of separate sub-compartments,
in each of which a predetermined or measured quantity of water is introduced, and
each of which sub-compartments is separately provided with spraying pipes.
The pipes C shown are represented as supported by angle irons &*, but they may
be otherwise applied and connected.
D is the cover of the box or receptacle, being merely a flat lid hinged to the
upper edge of the receptacle. I prefer to provide the lid with an opening
controlled by a shutter or door, d, which will be raised by any excess of steam
present in the receptacle.. If desired the receptacle may be provided with a
discharge outlet or dump in its lower portion.
The arrangement of spraying or distributing pipes represented is a convenient
one, and it may obviously be modified without departure from the invention, and
in the matter of the proportioning and relative disposition of the coke-containing'
and water containing compartments radical variations can be made, it being,
however, of prime importance that the relative disposition of the respective
compartments should be such that the heat of the charge of coke can be radiated

page_text: through the walls of the partitions which happen to divide the respective
compartments.
It is proper also to state that the spraying or distributing pipes are simply a
typical means of communication between the water-containing and coke-containing
compartments of the apparatus as a whole, and that their arrangement is to be
preferably such that they are in communication with the upper portion or portions
of the water compartment and with the lower portion or portions of the coke
compartment, in order that they may receive the steam near the upper part or
parts of the water compartments and discharge it near the lower part or parts of
the coke compartment.
E is the main water supply pipe, from which a series of branches, e, lead to the
respective sub-compartments of the water chamber. Each branch is provided with
and controlled by a suitable valve or cock ex, so that the water supply may be
conveniently and accurately regulated.
The side walls of the receptacle are preferably both arranged or set in parallel
inclined planes, one of which, G, overhangs and protects the bottom of the
receptacle, and the other of which, H, slants outwardly away from said bottom,
s that when a charge of material is deposited in said receptacle the force of its
fall against the bottom is broken by its necessary contact with the inner face
of the wall H, which wall the charge encounters near its top, and down which it
rolls or slides.
As will be understood my improved quenching apparatus may be employed to
quench or arrest the combustion of coke produced in any type of coking oven.
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. An apparatus for quenching or arresting the combustion of incandescent
coke, by steam, consisting of a closed chamber or other receptacle adapted to
contain coke, provided with a second or external wall which forms with the wall
of the receptacle a water containing compartment or jacket in position to receive
the heat radiated from the coke, said water compartment being provided with
outlets leading to the coke receptacle, and means for supplying water to said water
compartment, substantially as set forth.
2. The improvement in the art of extinguishing or quenching coke herein set
forth, in which a body of water is maintained in position adjacent to a body of
heated coke so that the heat radiated from the coke is utilized to elevate the
temperature of the water and generate steam and said steam conducted to and
discharged upon said coke, substantially as set forth.
3. An apparatus for quenching or extinguishing coke by steam, consisting of a
closed chamber or other receptacle adapted to contain coke, a water containing
compartment or jacket in position to receive the heat radiated from the coke, a
water supply inlet opening into said water compartment, and steam outlets opening
from the upper portion of the water-containing compartment and discharging into
the coke receptacle, substantially as set forth.
4. An apparatus for querching or extinguishing coke, consisting of a closed
receptacle or chamber embodying a compartment adapted to receive a mass of
heated coke and a series of closed independent water compartments arranged in
such position as to expose the contents of all to the heat of the mass of coke, a
water inlet for each water compartment, and a steam discharge orifice leading from
cach water compartment to the coke receptacle, substantially as set forth.
5. An apparatus for quenching or extinguishing coke, consisting of a closed
chamber, or other receptacle, adapted to contain coke, provided with a second or
external wall which forms with the wall of the receptacle a closed water-containing
compartment or jacket to receive the heat radiated from the coke, supply inlets
leading to said water compartments, and pipes embodying discharge perforations

page_text: leading from said water compartments to and distributed around the wall of the
coke receptacle, substantially as set forth.
6. An apparatus for quenching or extinguishing coke consisting of a coke
receiver the wall of which embodies a series of independent water compartments.
placed one above the other so as to expose all to the heat of a contained mass,.
which compartments embody liquid orifices and water supply inlets, substantially
as set forth.
7. An apparatus for quenching or extinguishing coke, consisting of a coke
receptacle the walls of which are inclined as described, which receptacle embodies.
a water compartment arranged to expose its contents to the heat of a charge in
the coke receptacle, and means for discharging the contents of said water com-
partment into the coke receptacle, substantially as described.
