Leaching characteristics of lead from melting furnace fly ash generated by melting of incineration fly ash

Journal of Environmental Management, 2012
This study investigated the effect of the chemical composition of incineration fly ash on the leaching characteristics of Pb from melting furnace fly ash generated by melting incineration fly ash. Melting furnace fly ash from both a real-scale melting process and lab-scale melting experiments was analyzed.

Tracking of copper species in incineration fly ashes

Journal of Hazardous Materials, 2006
Speciation of copper in the incineration waste heat boiler (HB) and the down stream electrostatic precipitator (EP) fly ashes during the flue gas cooling down (1123-->473 K) has been studied by X-ray absorption near edge structural (XANES) spectroscopy in the present work.

Chemical stabilization of MSW incinerator fly ashes

Journal of Hazardous Materials, 2002
In this work, the relationship between heavy metal content of fly ash and that of the solid wastes incinerated was correlated and compared. It is found that the former is a function of the latter. Hence, it is important to prevent heavy metal-rich wastes from being incinerated in order to reduce the content of toxic metals in the fly ash.

Stabilization of Fly Ash from Municipal Incinerators

2009 International Conference on Environmental Science and Information Application Technology, 2009
Municipal solid waste incinerator by-products include fly ash and air pollution control residues. In order to transform these wastes into reusable species, soluble alkali chlorides must be separated and toxic trace elements must be stabilized. In this paper, alkali chlorides can be extracted efficiently in an aqueous extraction step combining a calcium

Dioxin and Fly Ash Free Incineration by Ash Pelletization and Reburning

Environmental Science & Technology, 2001
Dioxins (DXNs) in municipal waste incinerator fly ash were effectively reduced by pelletizing the mixture of ash, cement, and sodium phosphate and reburning the pellets in a laboratory scale bubbling fluidized bed (BFB) furnace. Three types of pellets--A, B and C, of various sizes and compositions were used in the experiments.
