Power
Plant
Pollution
and
it's
Control
The purpose of this topic is to introduce the readers with the sources polluting the atmosphere. The electric power demand is continuously increasing and it is expected that the demand would be doubled after every 7 to 10 years and the pollution of the environment would be rapid in the coming years.
The
electric
utilities
are
currently
faced
with
simultaneous
demand
for
increased
power,
and
the
demand
for
the
elimination
of
all
the
objections
attributed
to
hydro-electric
power,
fossil
fuels
and
nuclear
energy.
The
main
pollutants
from
the
thermal
plants
are
dust
and
objectionable
gases
like
CO,
CO.,
SO2,
NO2
and
many
others.
The
ash
is
also
a
problem
as
it
also
emits
heat
to
the
atmosphere
as
well
as
small
diameter
pollutants
carried
by
the
air.
The
pollution
from
the
thermal
plant
is
also
large
quantity
of
heat
discharged
to
the
atmospheric
air
and
water
used
for
condensing
the
steam.
The
pollution
from
the
nuclear
power
plants
is
radio-active
waste
in
form
of
gases,
liquids
and
solids
whose
radio
active
property
may
retain
number
of
years.
The
dumping
and
leakages
of
these
wastes
are
the
major
problems
in
nuclear
power
plants.
The
pollution
problem
is
mainly
faced
by
the
developed
countries
like
U.S.A.,
U.K.,
Japan
and
France
and
positive
steps
are
already
taken
by
the
Governments
to
reduce
the
pollution
effects.
An
increased
concentration
of
man's
activity
in
to
any
area
is
another
cause
of
air
pollution.
In
USA,
50%
of
the
total
emissions
are
released
over
leas
than
1.5%
of
the
country's
area.
No.
doubt,
presently
the
percentage
pollution
by
electric
plants
is
considerably
less
(15%
of
total)
but
it
is
estimated
that
the
source
of
pollution
will
increase
rapidly
as
the
power
demand
increase
is
very
very
rapid.
