ROD SCRUBBER Abstract of the Disclosure A venturi-type rod scrubber for effecting the cleaning of the flue gas produced as a by-product of the combustion process that occurs during the course of the operation of fossil fuel firing steam generators, before the flue gas flows up the exhaust stack and is released to the atmosphere. The subject scrubber includes inlet means through which the flue gas enters the scrubber. A first spray system is suitably mounted in juxtaposed relation to the inlet means so as to be operative to intro- duce liquid into the stream of flue gas entering the scrubber through the inlet means. In alignment with but in spaced relation to the inlet means, the scrubber is provided with a throat region, i.e., a region of restricted cross-section. A plurality of spaced rows of parallel rods are suitably mounted within the throat region so as extend substantially perpendicular to the path of flow of the flue gas flowing therethrough. Interposed between the inlet means and the throat region, the scrubber is further provided with a second spray system that is also operative to introduce liquid into the flue gas stream. The first spray system and the second spray system mutually cooperate to effect an even distribution of liquid across the entire cross-sectional area of the throat region that is being traversed by the flue gas as the latter flows through the scrubber. This even distribution of liquid provides for an efficient removal of the par- ticulate matter, entering the scrubber in entrainment with the flue gas. Concomitantly a reduction is achieved in the amount of particulate emis- sion being released from the stack to the atmosphere.
