ing frequent firing. Proper regula-
tions of the draft is therefore es-
sential.
In furnaces and boilers the damp
er and the firing door fit so loosely
that enough air enters into the furn-
when the damper is closed. An op-
ening of about one-eighth inch in the
average damper will be enough.
IF the size of the furnace will per-
NIT, the fuel bed should be carried
about eighteen inches thick A thick
| fuel bed helps to check the draft and
gives slow uniform combustion and
| uniform temperature in the house.
With a thick fuel bed the fire will
last a long time without requiring
attention. If thin fuel bed is car
ried the coke burns too fast, giving a
hot, uneven fire that burns out quick
ly and requires frequent firing. A
thin fire also tends to produce more
clinkers.
One Shaking Day Enough.
"A coke fire requires less shaking
of the crate than coal fire. In or
dinary weather one shaking a day,
preferably in the morning, is all that
VIII be necessary. In very cold
weather the crate may have to be
shaken before each firing.
Usually better results are obtained
when the CRATE is not shaken too
much, and it should never be shaken
so much that pieces of hot coke fall
into the ashpit. Therefore, in shak-
ing the CRATE the ashpit should be
watched and the shaking should stop
as soon as the first sparks appear in
the ashpit.
Some people who have burned coke
for many years say that they get bet
ter results if they leave layer of
ashes about one to two inches thick
on the CRATE all the time. The ashes
help to check the draft and keep the
! hot coke from coming in contact with
the CRATE. Between firings the fuel
bed should be stirred as little as pos
) sible.
How to Handle Clinkers.
''lf clinkers form on the crate they
should be pulled out just before fir
ing. Usually the best time to remove
clinkers is in the morning, when the
I, fire is started for a days run. II
often happens that this one cleaning
I is sufficient, and sometimes the fire
may go two or three days without
moving the clinkers particularly il
the weather is mild. The less the
fire is disturbed the better the salts
faction obtained with the coke.
.The ashes should not be allowed
: to accumulate in the ashpit until i
d reaches the CRATE, for then the graf,

well to remove the ashes from tn,
ashpit every day.
For banking the fire over night
:, the fine particles from the coke pill,
q should be used. The fine pieces max,
: a denser fuel, reduce the draft through
e the fuel bed, and thus help in keepin,
y the fire over night.
g Keep Ashpit Door Closed.
: 1.-The fuel bed may be made still
u denser by lightly tapping the coke OIL
i the top with poker or shovel. Th
ashpit door should be closed as tight
ly as possible and the draft in tn
furnace reduced by opening the checl
: damper in the smoke pipe If tn
y ashpit door does not fit tightly, in or
b. der to keep the fire over night it ma.
'o be necessary to open the damper il
the firing door.

to start the fire quickly.
After about half an hour, whe

tude of the opening of the chec
