    摘要: A boiler plant comprises a fluidized bed boiler having a furnace (1), a flue gas duct (5) exiting the furnace, and a sorting device (8) which is arranged to separate a first fraction from the fly ash entering the flue gas duct, as well as a side duct (9) for leading the first fraction away from the sorting device (8). The boiler plant comprises a separator (10) for separating a first fly ash fraction from the flue gases flowing in the side duct (9). The sorting device (8) is arranged to separate into the side duct (9) the flue gases from a flow entering the flue gas duct (5). The flow in the side duct is more concentrated with respect to the fly ash and has a smaller gas volume than a flow that remains in the flue gas duct (5) after the sorting device (8). As to its hazard classification, the first fraction of fly ash obtained by the separator (10) corresponds to bottom ash.

    摘要: A method for treating fly ash of flue gas exiting a furnace of a fluidized bed boiler. A side flow conveying a first fraction of fly ash is separated from a flow conveying a second fraction of fly ash. After the separation, the side flow conveying the first fraction has a higher solids content than the flow conveying the second fraction. The first fraction of fly ash is separated from the side flow at a separation temperature of at least 400° C., whereafter the first fraction of fly ash is discharged from the process.
