Abstract: Technique situation of removal of SO2and NOxis described,and conclusions as followswere drawn through analysis and comparison.
The investment and running cost of SO2removal in wet method is high and its byproducts are useless;on the contrary,the cost of SO2removal
by use of electron beam is 20%~30% lowerthan that inwetmethod,but strict and giant radiation defensive facilities are neededwith expens-
