Determination of the Pb, Cr, and Cd distribution patterns with various chlorine additives in the bottom ashes of a low-temperature two-stage fluidized bed incinerator by chemical sequential extraction

To compared with different metal distribution patterns on the first-stage sand bed in the LTTSFB incineration under the various Cl additives. The results showed that polyvinyl chloride addition increased metal mobility in the reacted sand bed. NaCl addition reduced metal mobility due to the formation of eutectic material.
