Pulsed power has been used to remove nitric oxide (NO) in a mixture of nitr
ogen, oxygen, and water vapor simulating the flue gases from a power statio
n stack. The effect of the pulsewidth at a fixed applied voltage on NO remo
val concentration was studied. The dependence of the energy efficiency of t
he removal of NO at a fixed applied voltage on the pulsewidth, on the remov
al ratio of NO and on the discharge current was investigated, This removal
energy efficiency increases with decreasing pulsewidth and decreasing remov
al ratio of NO.
