Fluidized bed coal combustion is a promising technology for using coal in an environmentally acceptable manner. Trace elemental constituents in fly ash from an experimental atmospheric pressure fluidized bed combustor (AFBC) are reported and compared with pulverized-coal combustor (PCC) ash data and those from other fluidized bed combustors. Bulk and size-separated particles were collected and analyzed by using spark source mass spectrometry.Fluidized bed combustor ash was similar to PCC ash in minor and trace element composition. However, AFBC ash showed less size dependence of elemental composition than has been reported for PCC ash. Bulk particle elemental composition varied with sampling position within the effluent stream. Penetration of elements through each cleanup stage and elemental enrichment were a function of the cleanup stage and the element under consideration.
