The formation of dioxins in municipal solid waste incineration processes has been investigated using a laboratory-scale fluidized-bed incinerator. As the dioxins formation is influenced by many factors, in particular combustion characteristics such as air ratio, temperature, and residence time, the laboratory-scale fluidized-bed incinerator was conducted such that each factor could be varied independently. In the experiment, artificial refuse-derived fuels were used to ensure experimental accuracy. To elucidate the conditions of the dioxin formation in a municipal solid waste incinerator, a theoretical analysis was also conducted on the basis of chemical equilibrium. From the chemical equilibrium considerations and the experimental results, we conclude that the formation of dioxins in municipal solid waste incinerators occurs as a result of the heterogeneity of components in the combustion field.
