Abstract: A nozzle assembly includes at least one nozzle (1) for the injection of liquid moistening medium into a flow of flue gas, especially in view of cooling the flue gas, and a body (2) for directing the moistening medium to the nozzle. Nozzle (1) and body (2) are essentially disposed in a flue-gas flow duct or the like. In the flue-gas flow duct is fitted a housing (3) which essentially surrounds nozzle (1) and body (2). Housing (3) ia provided with an an aperture (10), which can be closed by a closing means (9) and through which a jet of moistening medium passes into a flow of flue gas.

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separately into the reaction zone at several points, and finally from the opposite end a flue gas suspension is withdrawn and directed to dust separation (5).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.
