ABSTRACT:
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 includes passing the oxygen-containing flue gas through the waste gas burnout zone. The oxygen-containing flue gas is tempered by lowering a temperature of the oxygen-containing flue gas. The oxygen-containing flue gas is passed through a sufation zone so that the oxygen-containing flue gas has a temperature interval of between 700 and 900° C. during a time period of between 2 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.
