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separately into the reaction zone at several points, and finally from the opposite end a flue gas suspension is withdrawn and directed to dust separation (5).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: The invention relates to a process for separating off sulphur dioxide from boiler flue gases. In departure from the processes already known, in addition to the substance (4) to be burned and the oxygen-containing gas (5), pulverulent calcium oxide or carbonate or magnesium oxide or carbonate (6) is introduced into the boiler (1) in an excess in relation to the sulphur dioxide gas forming in the combustion chamber and water (9) is sprayed separately into the calcium oxide-containing or magnesium oxide-containing flue gases (8) thus obtained in a stage (2) separate from the combustion chamber. Alternatively, the pulverulent oxide (6') can be introduced directly into the flue gases coming from the boiler (1). … …

Abstract: In addition to a sulphur-containing fuel (4) and an oxygen-containing gas (5), a pulverous alkali metal or alkaline earth metal oxide or carbonate (6) (particularly calcium or magnesium) is fed into the furnace (1) in an amount in excess in proportion to the sulphur dioxide gas formed in the combustion chamber of the furnace, and water and/or steam (9) is sprayed separately into the calcium oxide-containing and/or magnesium oxide-containing flue gases (8) either in the furnace or after leaving the furnace. Alternatively, or in addition, the pulverous oxide (6') can be fed directly into the flue gases (8) leaving the furnace (1).

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: The process and device can be used for removing of gaseous sulphur compounds in particular sulphur dioxide present in the flue gasses, in the form of solid compounds - sulphates and sulphites. The flue gasses (16), containing sulphur dioxide, are fed into one end of an oblong reaction zone (4), into which pulverous calcium compounds and water are separately fed at several points along the reaction zone, and from its opposite end a flue gas and solid compounds suspension is withdrawn, said suspension being directed to dust separation (5). The problems, involved in the preparing handling and spraying of an agueous slurry, are avoided by feeding of the pulverous reagent and the water separately into the reactor (4), the reaction conditions and the retentation time in the oblong reactor (4) can be regulated easily.
