Utilities Commission Chairman
Tells How to Use Grades and
Varieties in Furnace.

Walter C. Allen, executive secre-
tary Of the Public Utilities Commits
sion. today made public q set Of rules
for househulders, to be their guild
ance in using coal and coal suDsti-
These rules were compiled by the
American Society of Mechanical En-
gineers, and recommend them to
the attention of every coal user In
Washington" Mr.. Allen said.
The rules follow: !.
Rules for burning anthracite coal,
large size:
level with fire doors.
2. Shake the CRATE to remove ashes
and lower the fuel bed, but stop when
the first live Goals appear.
8. Fresh fuel should be spread
evenly over the entire CRATE area. "A
heavy firing, say six to, eight inches
deep, can be made if desired, and will
last for six to eight hours, For quick
kindling the fire bed should be made
fairly hot before adding fresh fuel.
4. After firing keep the hampers
wide open until blue flame appears,
then check off the draft as much as
necessary to keep the fire burning al
the desired rate. The proper setting
OF the campers must be learned by
experience for each furnace. This Is
because Of the variation In the draft
available for different Installations.
For Smaller Sizes.
Rules Cor, burning coke and anthra.
cite, pea or buckwheaf:
!. Carry q deep bed OF fuel, even
above the level Of the fire door.
2. Shake the crate to remove
ashes and lower the fuel bed hut
stop when the first live Goals ap.
pear.
s. Spread q thin layer OF antIlra.
cite over the entire CRATE and allow
q few minutes for this fuel "a
ignite. Next I'LL the fire pot with
coke and allow this to burn until
blue flame appears, then add an.
other layer of anthracite.
4. After firing and seeing that the
charge 10 ignited check off the draft
to the desired point for slow burn
ing.
S. When banking the fire for the
night, use less coke and more an
thracite. but otherwise fire in the
same manner.
6. Anthracite, pea or buckwheat
can often be used alone with sue.
cess. This will happen when the
draft Is unusually good and the
furnace Is amply large. Small size
anthracite ignites slowly. It Is best
to fire one-hah Of the crate at a
time, allowing the first half OF the
charge to ignite before adding the
second half. Small sizes may be
used in the fall and spring II not in
the winter.
Rules for burning wood and
anthracite, pea or buckwheat:
1. Follow the rules for coke and
anthracite, substituting block wood
for coke. It Is highly important to
see that the fuel is properly ignited
and giving off flame before closing
off the drafts.
Rules for Bituminous Coal.
1. Bituminous, or soft, coal viii.
as q rule, give out less heat than
anthnRcite when fired In the ordi-
nary residence heater. Hence more
attention will usually be required
when using soft coal.
2. A deep fuel bed is desirable,
also. as q rule, more draft by the
campers.
8. After the fuel is partly burned,
breaking up the fire bed with &
hoe or poker IL the fuel bed is
caked.
4 Stir up the fire ana get II hot
before adding new fuel.
5. Preliminary to firing and new
charge, push the burned fuel to the
back or sides OF the fire boz, heap
ing II high up on the sides of the
fire box wall. Fire fresh fuels into
the hole in the hot fuel bed, making
Il level with the heaped-up burning
fuel.
9. After firing, check the draft to
make the fire burn slowly. setting
the hampers as found best by ex-
perience.
z. A large charge Of soft coal will
burn slowly for several hours, CIV
ing out moderate heat. If more
heat is demanded, 1t can be secured
by breaking up the partly ignited
mass with the fire tools.
8. A little air should be admitted
through the slides in the fire doors
when burning bituminouS coal
