<p>METHOD AND APPARATUS FOR TREATING FLUE GASES A method and apparatus for treating the flue gas, which is produced as a by-product of the combustion process that takes place during the course of the operation of a fossil fuel-fired steam generation unit. In accordance with the subject method and apparatus, the flue gas is made to pass through an air quality control system embodying a particular arrangement of scrubber means and spray tower means, before the flue gas is released to the atmosphere. The treatment of the flue gas consists of feeding the flue gas to the inlet of the air quality control system, passing the flue gas through spray tower means to effect the removal of sulfur therefrom, effecting a first change in the direction of flow of the flue gas through the air quality control system, effecting a second change in the direction of flow of the flue gas through the air quality control system, passing the flue gas through rod scrubber means to effect the removal of entrained particulates therefrom, from the rod scrubber means passing the flue gas through a dropout section to encourage agglomerates to fall out, effecting a third change in the direction of the flue gas through the air quality control system, passing the flue gas through a bulk entrainment separator and demister means to effect the removal of entrained fine water droplets therefrom, and exhausting the flue gas from the air quality control system.
