Abstract (in english)
   The speciation of potentially hazardous elements in residues from fluidized bed combustion (FCB) residues and products made of the was studied with Noth Bohemian lignitous coal. The FCB residues differ significantly from those prepared by classical technologies in phase composition as well as in trace element speciation. The content of some (esp. volatile) elements is higher in FCB residues, yet their form of occurrence is less environmentally dangerous and could be made even less hazardous by pelletization. Important factors enhancing the fixation of practically all studied trace elements are high alkalinity of the residues, ensured by surplus alkaline additive premixed with the sulfide-rich coal, and enhanced formation of ettringite in pelletization of the residue. In North Bohemian coals, high arsenic risk can be lowered by using FBC technology (in contrast to classical one) and further minimized by residue pelletization.
