Abstract (en)
[origin: WO2018108561A1] In the context of a flue gas treatment method in which, downstream, in the flue gas flow direction (R), of a fossil-fired boiler of a steam power plant a carbon-containing adsorption medium in the form of fine particles, in particular activated charcoal or activated coke, is introduced and/or sprayed into a flue gas flow flowing in a flue gas duct (5) of the boiler in order to separate out heavy metals, in particular mercury, the purpose of the invention is to identify a solution by means of which the distribution of the carbon-containing adsorbent in the flue gas is improved and the separation capacity thereof for heavy-metals, in particular mercury, contained in the flue gas is increased. This is achieved by generating, in the flue gas duct (5) and by means of at least one first swirling means (10, 10'), in particular a first static mixer, arranged in the flue gas duct (5), at least a first flue gas swirling zone, in particular on a downstream side, with respect to the flue gas flow direction (R), of the at least one first swirling means (10, 10'), and by introducing and/or spraying the adsorption medium into the swirled flue gas flow at least in this first flue gas swirling zone.
