IMPROVEMENTS IN APPARATUS FOR DRYING AND BURNING PEAT
Year: 1884

page_text: I SAMUEL DEADMAN Cox of New Charlton, in the County of Kent, Chemist
do hereby declare the nature of said invention for "IMPROVEMENTS IN
APPARATUS FOR DRYING AND BURNING PEAT' "and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention relates to apparatus for the treatment of peat to prepare the same
for use as stable litter or for manuring or other purposes.
This
When peat is properly dried it can be used instead of straw or chaff as litter for
horses or other animals, and one object of my present invention is to provide a kiln
for drying peat for this purpose in a convenient and economical manner.
drying kiln consists essentially of a building with a pipe or pipes suitably arranged
therein and supplied with steam from a generator.
For this
In cutting the peat from the moor or moss it will be found that some portions
thereof are not adapted for use as litter; another object of my said invention is
therefore to utilize these portions which would otherwise be wasted.
purpose I provide.in combination with the drying kiln, one or more kilns wherein
these portions may be burnt and thus reduced to ashes and I so arrange the
apparatus that the heat developed by this process can be utilized in drying peat for
the purpose above specified, either in conjunction with the steam pipe or pipes
above mentioned or otherwise.
The ashes of the peat can be used as manure or as a substitute for sand or emery
in the grinding of valves into their seats, or for other purposes.
My improved apparatus is illustrated in the accompanying drawing, in which
Figure 1 is a horizontal section of the said apparatus.
Figure 2 is a section on the line x, x, Figure 1, with some of the parts shewn in
elevation.
Figure 3 is a section on the line x, x1, Figure 1, with the kilns for burning the
peat shewn in elevation.
Figure 4 is a vertical central section, drawn to an enlarged scale, of one of the
kilns for burning the peat, with the cover of the said kiln removed.
Like letters indicate corresponding parts throughout the drawing.
My improved drying kiln is constructed as hereinafter set forth, that is to say :-
a is a building which may be of any convenient dimensions but which I prefer
should be about twenty feet square and about ten feet high. This building has an
aperture in the dome or roof a¹ and a pipe b extends from the said aperture to an
exhaust fan or similar apparatus at c driven by an engine at d in order to cause &
circulation of air in the building a and maintain the same at a uniform or nearly
uniform temperature throughout. At one side of the building a is a shed a' wherein I
place a steam boiler e, which may if desired be employed for supplying steam to the
said engine. A pipe f from the dome or steam chest of the boiler e enters the said
building a about seven feet from the floor thereof and is supported by the rods f¹
suspended from the beams a³. This pipe is preferably slightly inclined downward

its lowest point or to return to the boiler where it will be again converted into steam.
The said pipe is either bent in the manner shewn in the drawing or it is coiled or
bent in any other suitable manner, in a horizontal or nearly horizontal plane. It
is then bent at or near the centre of the kiln so that it extends downward to about
twelve inches from the floor, where it is coiled or bent in any suitable manner in a
horizontal or nearly horizontal plane and is supported by the rods or standards f³
being preferably slightly inclined downward for the purpose above specified. The
said pipe then passes out of the building a and re-enters the boiler c at or near the
top thereof. The said pipe therefore forms an extension of the steain space of the
boiler. A cock g is provided to permit the egress of the water of condensation
from the pipe f. And stop cocks h, i are provided upon the boiler for controlling
the flow of steam through the said pipe.
In using this apparatus the peat is cut into blocks in the ordinary manner, and
these blocks are piled one upon another so as to fill or partially fill the building a.
The steam circulating through the pipe ƒ maintains the air in the said building at.
a high temperature and thus dries the prat.
k, k¹, k² are kilns for burning the waste peat to reduce the same to ashes, these
kilns are made somewhat similar in form to ordinary lime kilns, but are each
provided with an annular chamber / communicating by means of passages m with
the external atmosphere and by means of the passage n and pipe n¹ with the
space o in the lower part of the building a. I make the latter with a perforated
false bottom p suitably supported about two feet above the base of the building a.
This false bottom covers the space o and serves as a support for the peat but at the
same time permits the heated air from the annular chambers to enter the said
building. The burning of the waste peat in the kiins k, k', k³ raises the tempera-
ture of the air passing through the chambers l, and the air thus heated is drawn
through the perforations in the false bottom p by the exhaust fan or similar
apparatus and assists in drying the peat placed in the kiln a. Each of the pipes n¹
may, if desired, be provided with a cock n³ for regulating or controlling the flow
of the heated air to the building a.
If desired the heated air can be forced through the drying kiln but I prefer to
employ an exhaust fan as above described.
In some cases, I may dispense with the steam pipe f, and employ for drying the
peat in the building a simply the heat from the kilns k, k, k. And in other cases
may employ the drying kiln provided with a steam pipe or pipes without the
kilns kk, k, but I prefer the arrangement shewn in the drawing.
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
First. The above described improved drying kiln wherein steam is conducted by
means of a pipe or pipes through the piled blocks of peat, substantially as, and for
the purpose set forth.
Second. The combination, with the drying kiln provided with the perforated
false bottom (with or without the steam pipe or pipes), of one or more kilns for
burning peat, so constructed and arranged that heated air can be drawn or forced
therefrom through the drying kiln, substantially as, and for the purpose, specified.
