Abstract (en)
[origin: CA2705043A1] The invention relates to a method for entrained-flow sulfation of flue gas constituents of a flue gas (9) containing oxygen in combustion systems having at least one combustion chamber. The aim of the invention is to develop a method for a practically complete entrained-flow sulfation of sulfatable flue gas constituents, thus allowing the formation of flue dust containing chloride to be minimized while reducing the use of sulfur oxides. Said aim is attained in that, after passing through an exhaust gas burnout zone, the flue gas constituents are conducted through a reaction chamber (22) in which the flue gas reaches a reaction temperature between 700 and 900 °C over a dwell time of 4 to 20 s, wherein the sulfatable flue gas constituents are transitioned (24) while flowing through into solid ash particles containing sulfate with the SO2/SO3 present in the exhaust gas and the halide concentration in the flue ash is reduced.
