Abstract:
In a process of eliminating contaminants in a waste gas by introduction of microwave energy into the electric field to which the waste gas is exposed, including the steps of:(a) flowing the waste gas to be purified through a dielectric tube; (b) creating an intense electric field in the waste gas to be purified by an incident and reflected electromagnetic wave generated by a magnetron in said dielectric tube through a tapered rectangular waveguide; (c) forming an atmospheric-pressure plasma with the help of an ignition system for purpose of dissociating the waste gas; (d) oxidizing and recombining the dissociated waste gas by injecting a proper reactive gas as an additive gas, wherein the gas to be oxidized and recombined is the byproduct.
