1. Flame
lengths
are
approximately
as shown in column
(2). Often,
tested boilers or furnaces will
operate
well with chambers shorter than the
lengths shown
in column
(2).
2. As
a general practice
any
of these dimensions can be exceeded without much effect on
combustion.
3.
Chambers in the form of horizontal
cylinders
should be at least as
large
in diameter as the dimen¬
sion in column
(3).
Horizontal stainless steel
cylindrical
chambers should be 1
to 4
inches
larger
in diameter than the
figures
in
column
(3).
4.
Wing
walls
are not recommended. Corbels are not
necessary although they
might
be of benefit to
good heat distribution
in
certain boiler or furnace
designs.

1. As a
general practice any of
these dimensions can be exceeded without much effect on combustion.
2. A
fiber-type refractory "rug"
or fill material to cover the floor area
of
the combustion space is
recommended
for
cleaner combustion and
to protect
the base.
3. When a
refractory
or
refractory
fiber
target
is used, the
lengths
in column
(2)
apply.
If the
lengths
are equal to
or longer than
in
column
(3)
no
target
material is needed unless
recommended
by
the boiler manufacturer.
