Abstract
Since fly ash plays an important role in thede novosynthesis of dioxins produced in the process of the incineration of municipal solid wastes, a number of experiments have been conducted to elucidate the formation mechanisms by heating fly ash samples. This paper reviews a wide range of such experiments, focusing on the influences of carbon source, chlorine source, oxygen atmosphere, temperature conditions and reaction time in the reactor system as essential or additional parameters. The reaction involves in the formation of dioxins from fly ash and the characteristics are examined. Furthermore, the paper also describes chemical kinetic modeling of the formation and its application.
