Tie following Thesis is a consideration of the prob-

lem of handlin3s sas coal at a certain Sus rlamt, with the

2
operation of which he writer was at one time conrected.

Tie plant is used for the manufacture of illwsinatings ¢

2 G2S
for a city of forty-two thousand population( 1014). The

Beas produced is mixed coal and carburete¢ water sas of

600 B.t.u. and 15 candle power.

The original installation put into service some
Lhirty years ago made water gas only. Vunen it became evi-
dent that coal gas was cheacer to vroduce, two coal cas
cenches were installed and found to be satisfactory. Then
four more bencnes vere installed and the old water Cas
plant was abandoned . As the comand increased, coal gas
benches were added until the present (1014) installation
of eleven benches of six retorts,each 14"x 28"x O', was
complete. about 1910 tne load became so variable that it
seemed advisable to install a water gas machine to carry
the peak loads. a V'-6" United Gas Improvement Co. water
Sas machine with scrubber and wash box was installed.

This equip&ment gave a maximum cavacity of 1,250,000
cubic feet per <4 hours with continual operation of the
water Gas machihe and medium quality yield. The coal  $5as
benches were run on four hour heats and the usual churze
per retort was S00 lbs. This gives a daily coal consumntion
of 71 tons for gas makin= purposes. It was customary to use

the same kind of coal for bench fuel at an average con-
sumption , including waste of about 3c5 lbs. of fuel per
ton of coal carbonized. Tnis sums up to ll tons of bench
fuel per 24 hours. Total coal consumption per 24 hours was
then 2 tons of 2000 lbs. each.

This coal was usually 3,/4 lunp vest Virginia cas
coal, tho occasionally Youghiozheny coal was purchased.
It was delivered by the rail-road in all kinds of cars

on the comvany's siding,as shown on drawing No. 1. Crdin-

~

arily it was possible to fet the coal delivered in bottom
dump cars. Coal for immediate use could be dumred from fhe
bottom of the cars onto a brick pavemert at the south end
of the retort house( marked coal dock). When so unloaded

it was possible for the stokers to get their supply by
shovelling,.from the Ground pavement into the charging was-
oms. It was necessary to have one man on each shift to
trim the coal in the car, and to clean up and close the
pvockets. Figured on a basis of charging all of the stokers'
time to stoking and none to coal unloading( as was customary
in thot by the works management) it cost only 32.50 per

50 tons to unload or five cents per ton. It was impossible
however to unload,even 20; of the total coal in this man-
ner, because of the irregularity with which thw shipments
arrived. It was common for ten to fifteen cars to come at
one time, and then none for a week. To obviate payament of
demurrace charzes it was necessary to unload this coal in

to the coal sheds adjoinins tiie retort house on the east
Ci

and on the west.This was done by snovelling from the cars
into wheel barrows placed on vlank runvays on top of the
cars. The coal was wheeled into the shed arc dumped. Che
man on tie wheel barrow and two to shovel from the car in
the barrow were necessary. This method averased a cost of
20 g per ton to unload.

During a veriod of two weexs to two months each year
it was to be expected that coal shioments might be held up
entirely. This necessiated taking the daily coal supply
from the stock pile. Tne stock pile,containinzg about 3000
tons was located several hundred feet west of the retort
house,with structures intervening( see drawins lio. 1).

The price of stocking coal in that pile by means of men and
wheel barrows averaged 30¢ per ton. To reclaim that coal

by means of horse drawn wagons and men, handling by hand
and delivering to the front of the retort house averaced

a cost of 51.25 per ton.

Cn the average during a years time twenty per cent
of the coal would be unload<:d direct from the cars ata
cost of 5¢; 10°53 would be stocked and reclaimed from the
large pile at a total cost of 51.25 per ton; and 70> would
be taken from the coal sheds at a cost of 25¢ per ton.

During the year then the following would be spent for

nandling coal from the cars to the charsing wagon,-

This ampunt varied somewhat but there was always the
possibility of ti.e arrival of such conditions as existed in
the winter of 1916-1917, when all of the stock pile was
used up, tho during the preceding summer there had been an
unusually large one. The actual average cost then to unload
coal was 33.86¢ per ton. The costs as outlinedabove were
for the year 1914 when the cost of labor was 32.00 and’ 2.05
per day for common labor, and $2.50 for a wagon driver, and
21.50 per day for a team of horses. Since 1914 the labor
conditions have suffered considerable chan;je. Now common
labor receives 32.50 to $32.75 per © § hour day and the
stokers 33.00 per 1l hour day. In spite of the high wases
laborers are scarce and diffteult to control. The stokers
refuse to handle coal from different unloading places,and
object to going out of doors in tne winter tine. Jita all
it scems very cesirable to lessen the hand labor required,
both because of high cost, end because of the possibility
of strikes and the discontinuance of opsration. “ith labor
costs about 25° hicher in 1017 than in 1¢14 the yearly
cost to unload cecal required in 1914 would be #12 675 or
4&Z.3 per ton.

In 1912 the daily send out averaged 500,000 cu.ft.
in the summer and 700,000 cu.ft. per <4 hours in the winter.

Since then the increased use of gas for industrial purposes
and the normal increase due to growth in population has
given an average daily sendout of 1,000,000 in 1014 and
1,500,000 cu. ft. in L916. In Feburary 1917 the sendout

vas around 2,000,000 cu.ft. per <4 hours. These figures
plotted as in Fig. 1. indicate a load of about 3,000,000
cu.ft. per cay in 1018. It is difficult to prophesy what
it will be in 1020. If the rate of increase remains con-
stant the sendout will be 4,500,000 cu. ft. per cay. The
population is increasing so ravidly that the building op-
crations, including installation of gas services, have not
kept pace. Hence it is reasonable to assume , that the gas
sold will increase at the present rate and possibly faster.
Tne nopulation in 1916 was estimated at 65000 or 70000.
see Fig. 2 for increase in population in recent years. The
capacity of the plant showed sisns of needing an increase
as far back as 1913. Certain plans were then being fornu-
lated to replace some of the then present equipment with
more modern and efficient types, and to enlarge the works
capacity to care for the probable future needs as autlin-
ed above. It was planned to install in the very near fut-—-
ure @ new water sas machine to run in connection with the
one already in use; and also to put in the necessary addi-
tional scrubbin, and condensirg apdvaeratus.a new nolcer of
1,000,000 cu.ft. capacity was contracted for erection in
1615. A new retort house of inclingu oven retorts was pro-

Sosed to replace the old house of stop end retorts, six per

bench. This installation would briny the coal gas capacity
of the plant to 2,750,000 cu.ft. daily, 2/3 of this to be
installed row ard 1/3 later(see Grawirng Ko. 2).. J/ith a
yield of 5.00 cu.ft. of gas per 1b. of coal this would de-
mand «7S tons of coal per <4 hours. If coal is used for
furnace fuel, there will be 41 more tons required, or a
possible total of 316 tons per 24 hours. To handle this
coal by the old-time hand methods would have cost 3122.00
per day pr 344,550 per ;ear, a cost which is obviously
pronibitive. Hence the necessity for a coal handlincs sys-
ten.

referring to drawing Io. 2, the extersions alreacy
Dlanned are shown in diagram. These are the new purifying
bosses to care for the new autput capacity; the new water
cag macnine; and the new boiler to furnish steam for it.
The new governor and booster room is shown and will remove
those articles from the basement of the office, where they
have been a source of danger. South of this is tne new con-
denser and exhauster room. Tne proposed new retort nouse
is shown just east of the 300,000 cu.ft. nolder

Assimiing that the working hours in such industrial
plants will soon be on an eight hour day basis, it becomes
advisable to ve able to unlcad, crush and store in bunkers
for use in the retort house at least one days supply in

the working time of eight hours. It will be also wise to

we
2
re)

have coal handling ca»acity sufficient to unload reserve

coal and place it in the stock pile. In my judgement there
~J

should be a coal storaze of at least 200 tons in connec-—
tion with the retort house, yreferably an overhead bun-
ker, because the oven retorts are charged at the top end
coy sravity from travelling weighing larries; also it
should be possible to unloud ard stock 6 to 7 carloads
ver day besliiles the daily consumption. This makes 13 car-
leads per day to be handled, or about €50tons ,to handle
which, a capacity of about 80 tons per hour will be neces-
sary. In case of excessive demand above this amount, the
resort to overtime of to two shifts would solve the pro-
blen.

To furnish two montns reserve coal in the stock pile
it would be necessary to store 20,000 tons.

then the problem reduced to its simplest terms con-
sists of designing a systemtthat will (1) stock about
20,000 tons of coal at the rate of 325 tons per day, and
reclaim it at the same rate when needed; and (2) that
will at the same time unload, crush, and deliver to over-
head bunkers 325 tons per day for current use. This sys-
tem should do its work wil& a minimum of total cost and
be so gesigned that future growth will be possible.

Tne second requirement will be taken up first. From
the nature of the ovens, which are inclined and charsed
from the top it seems advisable to build an overhead
hovper type of coal bunker. The coke storage space is

between tne retort house and the river, and therefore
tie ovens ought to be so placec tnat the cischarzing side
of the oven stack will te on the north. The plan is to
convey the coke to quenching rockets and then to tne east
end of tne oven stack, and from there transfer by travell-
ing crane and buckets,eitner to a crusner and ecreens,or
to tne yard storaze of run of oven coke. The charging
side of the ovens is then on the south so that the coal
bunker must be there also. ( A consideraticn relative to
future extension is taken up later). The charges will be
distributed thruout the day at sufficient,intervals, so
that the quality of gas will not vary too Sreatly. sence

the coal burker ought to hold encugh coal to last fron

the end of one eight hour cay to the beginnirg of the

--

next, or an 1% hour suodly equal to <00 tons. For this
purvese I have chosen an elevated hovper type bunker
made of steel and lined with concrete to protect th
steel from corrosion. See crawin; lo. 3 for size and
refer to specifications for further details.

The coal for use in the ovens musf pass an 1," screen,
and since it is not always economical nor possible to
buy this size at the mine, nor wise because of breakase
and consequent waste, it is tnerefore necessary to in-
gtall a coal crusher. The coal can be bousnt to be deliv-
ered in hosver bottom cars which will permit of unload-

ing by gravity into a track hopper.
CO

To handle the coal for daily conswaiption then the
following eyuinment must be provided for a capacity of
40 to 50 tons per hour,-

a track hopper,

feeder,

crusner,

conveyor elevator,

coal bunker.
These pieces of apparatus will handle the coal with the
least amount of hand labor and with minimum cost for main-
tenance.

In the future if additional cavacity is needed @ new
Stack of ovens will be necessary. It is impossible to
extend the »resent oven stack,because it borders the road-
way on one end and the larger holder on the other. Hence
this coal handling apparatus is designed for the maximum
capacity of this oven stack,includir; tne one third more
to be added to that now beins built. Later on I have taken
up the matter of additional ovens and the coal handling

plant for then.

The only available locaticn for railroad side track
for delivery of ccal to the north side of the oven stack,
and for shipment of coke is between the river and the S00,
COO cu. ft. holder. All other ways of approach are estopped
by buildings already in ;lace. by reference to drawing No.
ce it is aprarant that it is possible to brings a track fron
the main line of the Grand Trunk Railway along the river ,
northpf the holder and up to the north side of the oven
stack. This track will traverse tie large triangular open
space west of the nolder and provide yard storage space
for coal stock. This property was owned by the Railway Co.
in 1€135 but has recently been purchased by the Gas Co.

this track will than be brot to and cver a track
hopper on the nortn side of the oven stack,and extended
ceyond as far as possible to provide switching space for
empty cars. In the future another stack of ovens might
well be provided for. The proposed loeetion for this
stack is shown in heavy desh lines on drewing ho.4. The
charging side of this future stack will face the charging

side of the present stack, and make a firingpisle run-

i
ning east and west between the two stacks. Tne coal for
the new stack gan be brot in on the same track and unload-—-

ed by a Similar arrangement. To provide szace for this

possible future installation the present track hovtver and
il

bunker have been located to the west of the center of the
oven stack, Tae new installation can be placed acjacent
to it and just east of the center line. The csereral lay-
out 1s snown on arawings to. 5 and 4, and is described in
the specifications.
to liandle from cars te stock pile a aaily amount

of 525 tous of coal, or to de able to reclain the same
mount, will require a cavcacity of 40 tons per nour. The
cheapest method both in first cost and in operation to
handle such coal( 3/4 lunp) to and from open stcruse on
the cround is by means of the locomotive crane and “rab
bucket. For this purpose agoton eight wheel truck steam

not be reached by tie crane, wnen taking coal from the
coal pit, without the construction of too many sits, and
so it is planned that for storase in such slaces Bhe grab

and dumped to completely empt: jhhen. The locomotive crane

will also te of special value to move cars in the yard,
and thus be independent of the Railway yarc men. Drawings

the cecal pit and a typical cress section of the storase
yard, showing certh of coal piles, the track distances,
and relative location of crane end coal pit. Drawing No.5

For future growth it will be possible to place the
tracks on low trestles and thus make possible higher
storage piles. If this is done, and the reclaininz sveed
is to be increased, it will be necessary tc have eitner
a second locomotive crane, or a larger one, or to operate
the one during two shifts. If deeper piles are used, it
probably would be advisable tc separate tne yard into
unit pockets by concrete retainins walls, so that in case

of snontaneous combustion tlhe fire could be isolated and

the condition remedied,

wells of the coal pit for supoort and are incased in con-
crete to vrevent corrosion. the digging vit is surrounded
on three sides by a wall two feet above grade line to
prevent tne inclusion of foreign matter with the coal
and to prevent accid:nts to the opsratcrs.

Tne storaze vard hes been filled in until it is prac-

tically level. The Cwners will arrange with the Railwa;
Co. for the laying of the necessary; tracks thruout the
yard and for any necessary grading. the track sl.ould be
well laid and of substanthal weight, say rails of about
80 lbs. per yard.

Yen fillings the storage yard tne outer edses should
be filled first and then the space toward the center, pro-
vided it is planned to completely fill the yard. when com-
pletely full only the princival yard track would be left
uncovered with coal. Over this track the coal for daily

The Circular Yrack system of storing coal, as putlined
on drewing Lo. 4, has been patented by the Link belt Co.
of Chicaso, Ill. and the Cwners will make arrarcement

with that Company for the risht to use it in this layout.
