Abstract: Procedimiento para la purificación de gases de combustión, y aparato para el mismo. El procedimiento se efectúa dividiendo el gas de combustión caliente portador de polvo procedente del hogar, en la zona de separación (3) en un ujo principal (11) pobre en polvo, y en ujo secundario (12) rico en polvo, siendo introducida una niebla (14) de vapor o agua dentro del ujo secundario en un punto en que la temperatura de dicho ujo secundario es de 300 a 600º C. El aparato, tal como un ciclón, destinado al uso en el procedimiento anterior, que tiene unas boquillas (19) para introducir vapor o agua atomizada, y un conducto de conexión (12) entre el dispositivo de separación (3) y el conducto (11) de gas de combustión, con la finalidad de hacer que el ujo secundario rico en polvo activado de gas de combustión, se una al ujo principal pobre en polvo en un punto después del ciclón (3).

Abstract: 2064210 9101174 PCTABS00003 The invention relates to a process for the purification of flue gases by feeding (7) limestone into the furnace (1) of a boiler, by separating (3) the dusts from the flue gases at a point after the furnace, by hydrogenating (14) the separated dust, which contains calcium oxide, by returning (12, 13) it to the flue-gas flow (11) at a point after the separation point but before the reaction zone (4), in which additional water or vapor is fed (15) into the dust-bearing flue gas, whereafter the dust which contains sulfated calcium hydroxide is separated (5) from the flue gases (6) thus purified. According to the invention, the hot, dust-bearing flue gas coming from the furnace is divided in the separation zone (3) into a dust-poor main flow (11) and a dust-rich secondary flow (12), vapor or water mist (14) being fed into the secondary flow at a point at which the temperature of the secondary flow is 300-600 ·C. The invention also relates to an apparatus, such as a cyclone, intended for use in this process and having nozzles (19) for feeding in steam or for atomizing water, and a connecting duct (12) between the separation device (3) and the flue-gas duct (11) for the purpose of making the activated dust-rich secondaryflow of flue gas to join the dust-poor main flow at a point after the cyclone (3).
