ABSTRACT:
In an exhaust gas treatment process, the exhaust gas is first irradiated in the presence of ammonia to produce particulates, and is then fed into an electrostatic precipitator and then to a mechanical filter device, whereby the treated effluent gas released into the atmosphere is caused to satisfy the relevant dust regulation values in addition to being substantially free of SO.sub.x and NO.sub.x.
