An electron beam irradiation apparatus is employed for irradiating combustion exhaust gas with an electron beam to remove toxic components from the exhaust gas. The electron beam irradiation apparatus comprises an electron beam source (12) for emitting electrons, an accelerating tube (13) for accelerating the electrons emitted from the electron beam source, a focusing electromagnet (16) for controlling a diameter of an electron beam by applying a magnetic field to an electron beam having a high energy formed in the accelerating tube (13), an electromagnet (17, 18) for deflecting and scanning the electron beam by applying a magnetic field to the electron beam and an irradiation window (20) for allowing the electron beam to pass therethrough. The electron beam is focused a focus point by the focusing electromagnet (16) so that the electron beam converges once and then diverges, and then emitted through the irradiation window (20) to the outside. |
