■
After
initial
firing
of
furnace
at
design
temperature,
check fiber shrinkage in vicinity of burner tile. Fill
any voids with bulk fiber insulation to maintain a
gas tight seal between furnace interior and shell.
For Fiber Lined Furnaces:
(See Figure 3.4 and Figure 3.5)
• Be sure the gasket
is installed between the
burner
and be refractory combustor flange
.
• Install the gasket
between the refractory
combustor flange
and the furnace shell
.
• Coat the outside of the refractory combustor
with
an air setting refractory cement
. Also, fill
clearance gap between the furnace shell
opening
and the refractory combustor
with cement.
• Wrap the exposed refractory combustor
length
with two layers of continuous strip of blanket
insulation
.
• Compress and secure the blanket insulation
to
the refractory combustor
using a suitable, non-
metallic tape. Compression of the blanket insulation
should be at least 25%.
• Install the fiber insulation
tightly against the
wrapped refractory combustor
, following the
suppliers recommended procedure for anchoring
and compressing the fiber
.
Figure 3.4 Fiber Lined Furnaces
• For applications exceeding 2200 °F (1200 °C) install
a ceramic fiber board shield 11 suitable for the
furnace design temperature as illustrated in Figure
• Anchor the shield 11 to the refractory combustor
and the fiber lining
with a high temperature, air
setting refractory cement 12 and ceramic anchoring
devices 13 .
Figure 3.5
NOTE:
For furnaces that are unable to support the weight
of the refractory block, a stainless steel shelf can be
welded to the shell for support.
