Abstract:
1. A method for entrained-flow sulfation of sulfatable flue gas constituents of an oxygen-containing flue gas in an incineration plant having at least one combustion chamber and a waste gas burnout zone, the method comprising: passing the oxygen-containing flue gas through the waste gas burnout zone; tempering the oxygen-containing flue gas by lowering a temperature of the oxygen-containing flue gas; and passing the oxygen-containing flue gas through a sulfation zone so that the oxygen-containing flue gas has a temperature interval of between 700 and 900° C. during a time period of between 4 and 20 s so as to convert sulfatable flue gas constituents present in the oxygen-containing flue gas to solid sulfate-containing ash particles so as to reduce a halide concentration in ash deposits thereof.
