This paper presents a technique for the complete, simultaneous decompositio
n of CO2, SO2, and NOx, as well as the simultaneous removal of fly ash by u
ltra-high voltage pulse activation. Ultra-high voltage narrow guise is used
to make the gases in the reactor become active molecules, which are then d
issociated into nonpoisonous gas molecules and solid particles under the co
ntrol of a directional reaction model. By using a sufficient charge and a s
trong electric field, the fly ash can be removed. It becomes the carrier of
C and S, and its efficiency is 99.5%. Owing to the action of catalyst B (u
sing Ni as the mother's body), the activation energy of CO2, SO2, and NOx g
ases is reduced in great magnitude, and their removal Efficiency can reach
75 similar to 90% at normal pressure and 180 degrees C.
