Emission of Pb and PAHs from thermally co-treated MSWI fly ash and bottom ash process

Evaluation of the distribution patterns of Pb, Cu and Cd from MSWI fly ash during thermal treatment by sequential extraction procedure

“…The three different rotation rates included 0.89 rpm, 1.39 rpm and 2.0 rpm in this study. The detail operational conditions of this experiment were similar to those used by Chou et al [25].…”

“…Thermal treatment of the fly ash was conducted in laboratory apparatus and the experiment apparatus of this study was similar to that used by Chou et al [25]. This apparatus was a pilot-scale rotary kiln reactor with a thermal chamber (210 cm long with an internal [4] and [26].…”

“…However, very few reports have compared metal fractions in raw ash and treated slag. Chou et al [25] evaluated the emissions of Pb and polycyclic aromatic hydrocarbons (PAHs) from thermally co-treated MSWI fly ash and bottom ash process. In that study, the experimental results only showed the TCLP concentration of Pb.…”

Estimation and characterization of polycyclic aromatic hydrocarbons from magnesium metallurgy facilities in China

“…Khalili et al (1995) indicated that predominant PAHs in coke oven emissions were NaP, AcPy, PhA, Flu, Ant, and FluA, whereas Tsai et al (2007) reported that the major PAHs species were AcPy and BkF in the coke making process. In addition, the main PAH species in MSWI fly ash were low-ring compounds such as NaP, AcPy, and PhA (Chou et al 2008). The diversity of PAH formation from the Pidgeon process may come from combustion mode, temperature, air velocity, addition of secondary air, and additives such as desulfurizer (You 2008).…”

Occupational exposure and DNA strand breakage of workers in bottom ash recovery and fly ash treatment plants

“…Concluded the above findings, the toxic effect of residue from municipal waste incineration has been proved. The toxicity characteristic leaching procedure (TCLP) for bottom ash and fly ash have suggested that PAHs and some metal concentration, especially for Pb and Zn, in fly ash was higher than those of bottom ash [9][10][11]. It is highly like that the workers might overexpose to the hazards such as PCDD/Fs, PAHs and metal concentration while they handled the residue of incineration, especially in fly ash treatment plant.…”
