A steam scrubber system passes an exhaust gas to be cleaned into a steam scrubber chamber having substantially saturated steam therein. The substantially saturated steam particles have strong negative charges which attract positively charged particles to be extracted from the exhaust gas causing such particle to agglomerate and fall from the exhaust gas-steam mixture. Where it is desired to add a treatment chemical to the steam, a liquid containing the treatment chemical is atomized in the chamber. In a preferred embodiment, some of the inflow of steam is directed toward an impingement plate against which a jet of a liquid carrying a treatment chemical is directed for atomization and mixing with the steam. The treatment chemical is one, such as lime, slaked or unslaked, which would be ineffective if mixed directly with the steam. The resulting mixture may be passed into a cooling and demisting chamber before release to the atmosphere. The system may employ double steam chambers juxtaposed about a cooling and dimisting chamber in common, from where the cleaned gas is passed into the atmosphere or otherwise.
