INDUSTRY AND INFENIION.
IMPROVED MODE OF MANUFACTURING COKE. The
following very simple as well as at the sane time mex.
pensiye plan Of phurzing coke has been recently
proposed by Messrs Clavidge Roper and has attract
cd the attention of many engineers and would appeto
he well worth the serious consideration of those
esged in the manufacture Of iron, inasnuch ~ IL sp
pears by recent statement made by Mr.. Roper the
last meeting of tie South Wales Institute Of Engineers
that the large amount sulphur present in British pig
iron is due to the sulphur present in the coke which 10
emp,oyed in its manufacture With this fact before u.s.
which Mr.. Roper proved to be correct from several
analyses which he made of pig iron and Of coke, the
advantage, which this method appears to possess
would seem 10 merit serious attention The pa.entess
propose to apply the waste gases of blast for
nsces or other combustibe gases which not util
lied for the purpose Of causing the cooking, carbon
zaton Of coal in coke ovens, either alone, or ~ ao
auxiliary to the ordinary process OF coking, az well as
employing steam for the purpose of desolpLurizirg
coke. To attain this end, they proceed as follows:
The coke oven employed by Mcssn. Clsvidge &
Roper is furnished with false perforated bottom,
which placed at short distance above the true one
to receive the charges OF coal to be operated Uu
der the alse bottom current of any untitled
bustb,e gases is allowed to pass after the oven has
been charged in the usual way, sufficient air being
allowed to enter TO insure the combustion Of the
gas The heat thus produced will cause the cokng Of
the coal contained in the oven, partitions being en-
p'oyed by Of which the direct Of the dame
lay be DETECTED thus diiusing the heat uniformly
as possible under the false bottom IL ia also necessary
10 have a itack in connection with the fame spacs
under the oven, and by means Of damper on this
stack the heat Of the may in avery great measure
be regulated. The combustibe gases may also II de-
sired be applied at the top sides of the oven. When
tie conversion Of the coal into coke has taken place.
which result is indicated roughly by the disappearance
of heavy yelo red flame in the over and while the
coke s still at its maximum degree Of heat the supply
Of il lammabe gases is cut OFF, and current Of steam
is then admitted under the false perforated bottom,
care being taken to check its escape to the stack a.
much as possible. II is desired, steam may be ap-
Piled at the commencement Of the operation Of coking,
in which case if it is desired to utilize the waste cases.
they must be applied at the top sides Of the oven.
When any sphurous Goals operated on, IL will DO
found advantageous to provide for the combiced ass
Of the waste gases and Of the steam at tie time,
90 that til steam may be applied for longer tune.
The steam passed. under the false bottom, 10 forced
through the perforaons into the coke oven where II
retained under pressure as much a. possible BY clos
rg all the apertures frm the oven so that the coke
may be thoroughly permeated by the steam, which,
berg decOmposed by the nphce iron, any other
sulphde present. the hydrogen combines with the sui
plur ofbe suphide, carrying il of the gaseous state.
Where extremely ,ulphury Goals operated upon, II
i, recommended to employ superhested steam, 80 that
the mpoibg action may be exeted for the longest
time. Tie steam reqpired for mphurizng the coke
may be raised by means Of tie waste pest Of the coke

ertly, may he cooled in tho usual way; but Messr.
Clavdge & Roper show that by continuing the use Of
steam, the coke i. ex,insusbed and being thus in
AMBIGUOUS state, nearly co. may be very useful for
various purposes. One Of the most suphury Goals 10
S,uth Wales wa operated on by the paientees, and
by the application Of steam, the coke obtained from this
coal was rendered seryiceabe for the cupoa, fnery,
and blast iorna:e TO neither Of which uses il Vas for
merly adopted Messrs. Clavidge g. Roper have also
sppled tie ssme meas for the desulphurizaison Of
mineral charcoal, tr, as it il more frequently called,
soft coke, with the most satlsfs1tory resslts-tn
plates made with this fuel beng considered eqns.o
those made with charcoal.
