摘要: 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.

摘要: The invention relates to a process for the removal of sulfur dioxide from hot flue gases (8) which have been obtained by burning a sulfur-containing substance (4) in a boiler (1). In the process, a substance (6), such as lime or limestone, which reacts with sulfur dioxide to form a solid product is fed into the boiler or into the reaction zone (2) subsequent to the boiler, the hot flue gases (8) are cooled in the reaction zone (2) by feeding into it at maximum such an amount of water as the hot flue gases are capable of evaporating, and the substantially dry solid products are separated (3) in the form of dust (10) from the cooled flue gases. According to the invention, the flue gases (11) thus obtained are scrubbed (13) with an alkaline aqueous solution (15) in order to remove the remaining sulfor dioxide and dust from the flue gases, and part (9') of the cycled scrubbing solution (9) is fed into the boiler (1) or the reaction zone (2) in order to evaporate the water from this solution.
