Control
of
Nitrogen
Oxide
in
Power
Plants
The regulations on the nitrogen oxide emissions are becoming hard as it is one of the most offensive pollutants produced by combustion process An increased power generation activity has increased NO2 emission and it has become essential to limit its emission level as it has many bad effects on the human health. The oxides of nitrogen are the second most abundant air contaminant found in the thermal power exhaust.
The
control
of
NO2
pollution
has
proved
to
be
difficult
and
no
widely
applicable
method
has
so
far
been
developed
on
commercial
basis,
Measures
are
taken
at
different
stages
to
reduce
its
emission
before
the
gases
are
exhausted
to
atmosphere
