Sulfur oxides and other acid gases are removed from hot flue gases by dispersing and suspending an absorption agent and water, preferably Ca(OH)2 suspended in water, in a rising stream of hot gas at the lower part of a reaction chamber, where the hot gases are subjected to a rapid reduction in velocity. Sulfur oxides and other acid gases are absorbed on and reacted with the absorption agent in the presence of evaporating water producing a dry powder which is separated from the flue gas in a particle precipitator and partially recirculated to the reaction chamber. |
