Suspended particulate matter, including sulfur-containing compounds of calcium and magnesium, and sulfur oxides are removed from combustion gases by passing the gases successively through a high-velocity venturi-type scrubber and a wetted film-packed bed scrubber. Scrubbing liquid from the venturi scrubber and from the packed bed scrubber may, after being clarified, be recirculated to the two scrubbing stages.
