L-10
BEARING
LIFE:
The
theoretical
number
of
hours
after
which
90%
of
the
bearings
subjected
to
a
given
set
of
conditions
will
still
be
in
operation.
Also
known
as
B-10.
LAER
(LOWEST
ACHIEVABLE
EMISSION
RATE):
The
rate
of
emissions
that
reflects
either
the
most
stringent
emission
limit
contained
in
the
implementation
plan
of
any
state
(unless
it
is
proved
that
such
limitations
are
not
achievable,
or
the
most
stringent
emission
limit
achieved
in
practice,
whichever
is
most
stringent).
LAMINAR
FLOW:
Gas
or
fluid
in
parallel
layers
with
some
sliding
motion
between
the
layers.
LIQUID
FLOWRATE:
The
amount
of
water
or
“scrubbing
liquid”
introduced
into
a
wet
collector.
LOUVER:
A
device
comprised
of
multiple
blades,
which
when
mounted
in
an
opening,
permits
the
flow
of
air
but
inhibits
the
entrance
of
undesirable
elements.
LOW
NOX
BURNERS:
One
of
several
combustion
technologies
used
to
reduce
emission
of
Nox.
LOW
PRESSURE
CLEANING
AIR:
Air
at
less
than
30”
WG
used
for
cleaning
baghouses.
LOWER
EXPLOSIVE
LIMIT:
The
lower
limit
of
flammability
or
explosibility
of
a
gas
or
vapor
at
ordinary
ambient
temperature
expressed
in
percent
of
a
gas
or
a
vapor
in
air
by
volume.
