Pollutants in incineration flue gas

Previous studies have shown that pollutants from incineration include heavy metals, organic compounds, particulate and acid gas, However, most studies on a single pollutant, it is rare for a study to concentrate on all possib le pollutants and the relations between these pollutants under various inci neration conditions. The objective of this work was to experimentally study the effect of different operating conditions on the pollutants emitted dur ing incineration and the relations between these pollutants. The operating conditions of the experiments included the temperature of the combustion ch amber and the species of organics. The findings indicated that the concentr ation of hydrogen chloride (HCl) in the presence of polyvinyl chloride (PVC ) was higher than that of sodium chloride (NaCl). Regardless of what Cl-con taining feedstock was added, the concentration of chromium (Cr) was constan t. When organic chloride was added, Cr was the main metallic element which influenced the formation of polycyclic aromatic hydrocarbons (PAHs). On the other hand, when inorganic chloride (NaCl) was added, lead (Pb) was the ma jor element. (C) 2001 Elsevier Science B.V. All rights reserved.
