(ArcelorMittal)
and submits the
following
Pre-Filed Comments
for
the
Illinois Environmental
Protection Agency
(Illinois
EPA or
Agency)
for presentation
at the
1
st
round
of hearings
scheduled in the
above-referenced
matter
for
December
9,
2008.
Specifically,
the proposed
regulations at 35 Ill.
Adm. Code
Part
217,
Subpart
H apply to iron
and steel and
aluminum
manufacturing
and
regulate reheat,
annealing
and
galvanizing
furnaces. ArcelorMittal’s
Riverdale,
Illinois facility has
a permitted
roller-
hearth
tunnel
furnace
equipped with ultra-
low NOx
tube burners (ULNBs),
which processes
cast
steel
slabs.
However,
the tunnel furnace
cannot be
considered as a
reheat, annealing,
or
galvanizing
furnace
and the arbitrary
NOx
reduction
proposed is
inappropriate for the
tunnel
V
V
furnace
in
operation
at ArcelorMittal’s
Riverdale
facility.
ArcelorMittal
finds
that based
on the
applicability
provisions
provided in
the proposed
regulation
at 35 JAC
217.150, the
tunnel
furnace
is not subject to this
regulation.
Should the
Agency
deem that
ArcelorMittal’s
tunnel
furnace requires
regulation
under the
proposed rule, it will
be
necessary
for the. Agency
to
include
a
specific
defmition
and emission factor
for the
existing
tunnel furnace
at
ArcelorMittal’s
Riverdale,
Illinois
facility, recognizing
the unique
nature of
the
operation
and the advanced
NOx
/
control
technologies
already
in
use.
V
THIS FILING
SUBMITTED ON
RECYCLED PAPER
1.
For
clarification purposes,
a brief
background
on
these
types
of furnaces
within
the
iron
and
steel
industry
is provided
herein.
Annealing
and
galvanizing
furnaces
are
used
to
further
process
steel
that
has
already
been
hot-rolled
and
exists
as
a
steel
strip,
while
reheat
furnaces are
used
to
process
steel
slabs,
billets
and
blooms,
which
are
typically
considered
intermediate
products.
At
traditional
mills,
liquid
steel
is
cast
into
slabs;
the
slabs
are
then
stored
in
a slab
yard,
transported to
a reheat
furnace,
heated
to
a
temperature
sufficient
for
rolling,
rolled
into
a
strip,
and
fmally
coiled
as a
finished
product.
In 1986,
new
technology
was
developed
that
allowed
continuous
casting
of
thin
slabs.
At
the Riverdale
facility,
a
state
of
the
art
compact
strip
production
(CSP)
facility
was
constructed
and began
operation
in 1996.
The CSP
process
allows
liquid
steel
to
be
cast
into
thin
slabs,
which
then
directly
enter
a
tunnel
furnace,
before
being
rolled
into
a strip
and
coiled.
ArcelorMittal
Riverdale
casts
a
thin
slab
with
a
2-inch
height,
which
is
then cut
to
length
by the
shear,
and
conveyed directly
into
the
tunnel
furnace
which
serves
to
equalize
slab
temperature
prior
to
rolling
at the
hot
strip
mill
(HSM):
The
CSP
design
represents
advanced
energy
efficiency
process
technology
(and
emission
reductions)
compared
to
traditional
methods
of
making
“hot
bands.”
Clearly,
the tunnel
furnace
is
not an
annealing
or galvanizing
furnace.
ArcelorMittal
has
prepared
the
remainder
of
these
comments
to further
illustrate
that
a
tunnel
furnace
cannot
be
coisidered
as a
reheat
furnace.
-
2.
The
Technical
Support
Document
(TSD)
prepared
in
support
of
the
rulemaking
provides
a
general
description
of
reheat
furnaces;
however,
the Illinois
EPA
provides
no
proposed
definition
of
reheat
furnaces
in
35
Iii.
Adm.
Code
Part
211.
Temperature
and
fuel
mixture
are
two
components
used
in
defining
a
reheat
furnace.
As
described
in
Section
6.2.1
of
THIS
FILING
SUBMITTED
ON
RECYCLED
PAPER
the
TSD, the
typical temperature
range for a reheat
furnace is a
continuous 2150
to
2450°F.
A
typical
reheat
furnace must
increase the slab to
this
temperature
from
ambient
levels;
however,
the
tunnel
fuinace
at ArcelorMittal’s
Riverdale
facility
maintains
the
slab
at its cast
temperature
with
only.
a
small
increase
in
temperature from
approximately
1800-1900°F to
2040-2146°F.
The
maximum
temperature of the
tunnel furnace
is 2150°F, well below
a
typical reheat
furnace’s
capacity.
Additionally,
while
traditional reheat
furnaces use fuel-rich
mixtures,
the tunnel
furnace
uses
a leaner fuel mixture.
3.
Design parameters
also
differ in
the tunnel furnace
versus a
traditional
reheat
furnace:
ArcelorMittal’s
predecessor,
Acme Steel
Company,
applied for a construction
permit
for
the CSP facility, including
the tunnel furnace,
on
April 12,
1993. The application
stated that
“The
Tunnel Furnace NOx
control technology
is
planned to
consist of low NOx
burners and
burner
càntrol
equipment.
In the
unlikely
event of burner(s)
or associated burner
control(s)
malfunctiOflor
breakdown,
the tunnel
furnace
must continue
to operate because it
is
in-line
with
the
cOntinuous., caster and
is the only
outlet for cast steel
slabs. The
tunnel furnace
is not
designed
as a conventional
reheat furnace;
therefore, any slabs
that must be
diverted
are not
recoverable
by Acme.” In
review, it
was found that the burners
are equivalent
in design
and
operation
to
ULNB, not
LNBs (See
paragraph #4 below
for more
details).
As
previously
indicated,
the , tunnel furnace
receives
slabs
directly from
the continuous caster.
Unlike a
traditional caster
which produces
a slab that’ is
stored prior
to processing, there is
no place to
store the
slabs
and no way to
“reheat”
a slab
from
ambient temperature.
The
entire CSP process
operates
as one
continuous process
and all sections must
be operating
optimally to produce
a
quality
finished product.
Further,
the tunnel furnace oflen
holds
the
slabs
until
they
can be
‘processed
at the
downstream
HSM.
Slabs
are
only
held
to accommodate maintenance
of HSM

FILING
SUBMITTED
ON
RECYCLED
PAPER
equipment;
any
lengthy holding
time
is
detrimental
to
the quality
of the
slab and
thus
the final
product.
4.
ArcelorMittal’s
current
NOx
emission
factor
for the
tunnel
furnace
is 0.171
lb/mrnBtu
and
the
tunnel
furnace
already
employs
ULNBs.
Information
from
the manufacturer
of the
ULNBs, Bloom
Engineering,
is
attached hereto
as Exhibit
A.
In addition,
the Agency
has
already
testified
that
it
would
be
surprised
if
sources
were
required
to install
post-combustion
controls
to achieve
the
proposed
emission
limits.
See
R08-19,
Transcrzpt
from
October
14,
2Q08
heariiig,
pp.
27, 116-117,
171.
Notwithstanding,
while
reheat
furnaces generally
combust
fuel
under
higher
oxidizing
conditions
allowing
for
greater
ability
to use
post-combustion
controls,
the
tunnel
furnace
does
not
afford
this ability,
and
because
it is
already
employing
ULNBs,
no
additional
reductions
can
feasibly
be
achieved.
Furthermore,
the CSP
design (which
incorporates
the
continuous
caster,
tunnel furnace
and
HSM)
represents
advanced
energy
efficiency
process
technology
(and
emissions
reductions)
compared
to
traditional
methods
to
making.”hot
bands” using
“Reheat”
furnace
process technology
(e.g.,
casting slabs,
reheating
slabs
and
rolling
slabs
to
hot
bands).
For comparison
purposes, in
a April
1998 evaluation,
the
Riverdale
facility
CSP
process was
65%
more efficient
than
the
previous
production
operations
that
produced
hot
band
coil at
the
facility,
which
translates
into
a significant
reduction
of
baseline
NOx
emissions
in-itself.
The
advance
CSP (including
the
tunnel
furnace) process
technology
should
be considered
in
the
overall
evaluation
to
reduce emissions.
5.
Additional
variations
in
reheat furnaces
detailed
in the
TSD include
the surface
area,
thickness
and
composition
of
the
material
to
be heated.
ArcelorMittal’s
Riverdale
facility
produces
both
high
and
low carbon
grades
and carbon
alloy
grade steel.
Many
of
these
grades
(including
high
carbon
grades with
up to
0.95%
carbon; carbon
alloy
grades
with
specific
THIS
FILING
SUBMITTED
ON RECYCLED
PAPER
additions
of chromium, nickel, molybdenum, and vanadium;
and carbon
grade
steels with boron
additions)
are not typically produced at other facilities. The
continuous caster at Riverdale casts
a very thin
slab of approximately 2 inches in height,
compared
to
a traditional slab
height
of
9
to
13 inches.
These
production
variations also have
an impact
on
temperature and oxygen content.
A
reheat
furnace design affords a lower flame temperature at
the burner under higher oxidizing
conditions, which results in the ability to achieve lower
NOx.emissions. Because of the small
increase in temperature as stated above, the tunnel furnace does
not afford this ability. The
specific ratio of oxygen to gas is also important as the correct
ratio generates a proper scale
on
the slab, which can easily be removed by the descaler, and
prevents the scale from being rolled
into the strip at the HSM. As stated above, the
entire
CSP is a continuous
process and
any
scale
rolled into the strip can
lead
to issues with
product
quality. Unlike other
facilities
that operate
tunnel
furnaces, the Riverdale facility
does not
have
a second tunnel
furnace
or
shuttle furnace
that
can
be used to
divert
product
between
furnaces; nor does the
Riverdale facility
have any
downstream
fmishing operations
(such
as
pickling) to remove, scale.
Therefore, operationally
and functionally,
ArcelorMittal’
s
Riverdale tunnel furnace cannot be
compared
tO, or
considered
to be a reheat
furnace (or
even
compared to other tunnel furnace
facilities
for
that matter).
THIS FILING
SUBMITTED ON
RECYCLED PAPER
For
the above reasons, AtcelorMittal USA, Inc. requests
the
Agency recognize the unique
differences
in the tunnel furnace design and propose a specific definition for the existing tunnel
furnace recognizing
the unique nature of
ArcelorMittal’s
operation
and the advanced
NOx
control technologies
already
in use.

The
small
capacity
low
NOx
1430
Burner
Series
utilizes
Bloom’s
refractory
baffle
for
blame
stabilization.
The
baffle
design
induces
furnace
products
of combustion
back
into
the burner
port.
Port
geometry
and
mixing
velocities
control
the
amount
of
induced
flue
gas
to
maintain
flame
stability,
proper
heat
release
and reduced
NOx.
The excellent
flame
stability
allows
operation
with
exhaust
gas recirculation
to
reduce
NOx
further.
By
shielding
the
burner
internals
from
flame
and
furnace
radiation,
the baffle
minimizes maintenance.
The
burner
port
block
is
a
high alumina
refractorywith
an
iron
alloy
mounting
plate.
Six or
nine inch
port
blocks
are
standard.
The
unlined
burner
body
with
heat
resistant
alloy
iron is
suitable
for
air
temperatures
up to
1000°F
(538°C).
For
air
temperatures
greater
than
1000°F
(538°C),
special
designs
are
available.
Each
burner
has
a machined
integral
gas distribution
orifice
eliminating the need
for
individual
gas
balancing
or throttle
valves
ensuring
even
distribution
throughout
a
given
zone
with
approximately sized
piping.
Turndown
lances
and
momentum
jets are
available
options.
The 1430
Series
Burners
are
suitable
for operation
with
continuous,
intermittent
or
interruptible
pilots
utilizing
UV monitoring.
The
use
of flame
rods
for
main flame
monitoring
is
not
recommended.
Direct
spark
or
manual
ignition
is
also available.
The
1430
Series
Burners
operate
from
stoichiometric to
oxidizing
firing.
Pressure
balance
ratio regulator
systems
or
volumetric
fuel/air
ratio control
systems
can
be utilized.
CAUTION:
The improper
use of
combustion
equipment
can
result
in
