The so-called electron beam exhaust gas desulfurization and denitration method, in which this is removed from the exhaust gas by a suitable downstream dust collector (for example, an electrostatic precipitator) provided in the downstream area outside the irradiation room, is known per se.

In this case, the concentration of positive and negative ions generated between the electrodes due to the impact ionization of the electron beam on gas molecules is greatly distorted by the action of the electric field, with the negative ion concentration increasing near the positive electrode and the positive ion concentration decreasing near the negative electrode. The converted particles near the positive electrode are negatively charged by ion bombardment and are attracted to the positive electrode, and the converted particles near the negative electrode are similarly attached to the negative electrode and removed. The particle removal effect increases almost proportionally with the electric field, that is, with the applied voltage of the inserted electrode.
