The removal of NO from flue gas has been tested by using non-thermal plasma method

decomposing NO under effect of high energy electrons into non-toxic and harmless N2.Results of test show that the non-thermal plasma technology can effectively promote decomposition of NO.Under condition of input power of the plasma is 42 W

the temperature is 25 ℃

the volume ratio of NO is 500 μL/L

the volume of O2 is 3%

the remainder is N2

and the flow rate is 500 mL/min

the removal efficiency of NO reaches 99%.Along with increasing the input power of plasma

the removal efficiency of NO is gradually increasing

the influence of flow rate and concentration of NO at inlet upon the removal efficiency isn't large;the concentration of O2 has certain restrain effect on decomposing reaction of NO

when the concentration of O2 is in a range of 1%~5%

the removal efficiency all can reach 92% and more.
