ABSTRACT:
There is disclosed an apparatus for treating waste gas containing nitrogen oxides and sulfur dioxide by irradiation with electron beams with the addition of ammonia, which apparatus comprises a reactor having an inlet and an outlet for the waste gas and a window through which electron beams pass to irradiate the waste gas inside the reactor, an electron beam accelerator as a source of said electron beams and a dust collector which receives the irradiated waste gas and removes solid particles therefrom, characterized in that said apparatus further comprises two independently operating automatic controlling systems and a judging system; the first controlling system operates under normal conditions; the second controlling system operates only in the case of emergency when the judging system has detected abnormal changes with respect to the concentrations of NO.sub.x, SO.sub.2 and NH.sub.3 of the waste gas.
