After the coal is burnt, they are contained in the grains of respirable dust, which creates health hazard. The results of investigations into the distribution of several trace elements in granular composition of ash emitted from CFB boilers used in coal-fired heat and power station are presented. The research material was taken by means of a cascade impactor, enabling a different granulometrie fraction to be separated from a stream of dust that penetrated the electrofilter. The CP-AES method (inductively coupled plasma atomic emission spectroscopy) was used to determine trace elements after prior mineralization of samples by microwave method. The Authors presented the results of measurements and analyses, determining the ranges of trace elements' occurrence in dust, characterizing the distribution in PM,, PM25 and PM10 granulometrie fractions and determining the emission factors.}, type={Article}, title={The Occurrence of Trace Elements in Flue Gases from Circulating Fluidized Bed Boilers}, URL={http://www.czasopisma.pan.pl/Content/122848/PDF-MASTER/3_AE_VOL_36_4_2010_Konieczynski_The_Occurrence.pdf}, keywords={Hazardous air pollutants, air contamination with dust, coal combustion, CFB boilers, grain sizecomposition offlue ash, trace elements in the emitted dust, distribution in grain size fractions, emissionfactors}, }
