Abstract: The invention relates to a process and apparatus for causing the sulfur dioxide of flue gases to react to form solid sulfates and sulfites which can be separated from the flue gases. Sulfur dioxide containing flue gases (16) are directed according to the invention into one end of an oblong reaction zone (4), in addition to which pulverous calcium compounds and water are directed separately into the reaction zone at several points, and finally from the opposite end a flue gas suspension is withdrawn and directed to dust separation (5). By feeding the pulverous reagent and the water separately into the reactor 4, the problems involved in the preparing, handling and spraying of an aqueous slurry are avoided, in addition to which the retention time and the reaction conditions can be regulated easily in the oblong reactor 4.

Abstract: Method for sepg. gaseous sulphur cpds such as SO2 from furnace exhaust gases, comprises: (a) introducing a powdered alkali metal oxide and/or an alkaline with metal oxide and or a precursor thereof into the furnace as well as the S-contg material, and a gas contg. oxygen, or a solid which releases oxygen on heating is mixed with the gas contg. S leaving the furnace. (b) water or steam is sprayed separately into the furnace and or the exhaust gas to convert the oxide to hydroxide and thus reacts with the SO2; and (c) a solid is sepd. contg. alkali (ne)earth metal sulphate and/or sulphite.

Abstract: According to the method, to fuel, containing sulphur (4) and to gas, containing oxygen (5), into the furnace is led powdered calcium or magnesium oxide or carbonate (6) in excess regarding the sulphur dioxide, being formed in the combustion chamber. In a following stage (2) outside the combustion chamber in the chimney gasses (8), carrying calcium and/or magnesium oxide, is sprayed water (9) or steam. Alteratively, the powdered oxide (6') can be led directly into the steam gasses (8), leaving the furnace (1). In this way the feeding of suspensions, containing calcium, is avoided.

Abstract: The invention relates to a process for removing sulfur dioxide from the flue gases of a furnace. In a way deviating from prior known processes, in addition to a sulfur-containing fuel and an oxygen-containing gas, a pulverous oxide or carbonate of calcium or magnesium is fed into the furnace in excess in proportion to the sulfur dioxide gas formed in the combustion chamber, and water is sprayed separately into the calcium oxide bearing or magnesium oxide bearing flue gases in a stage separate from the combustion chamber. Alternatively, the pulverous oxide can be fed directly into the flue gases leaving the furnace.
