HCl and PCDD/Fs emission characteristics from incineration of source-classified combustible solid waste in fluidized bed

Abstract

A fluidized bed incineration experiment was performed by means of refuse-derived fuel (RDF) from source-classified garbage to study the emission characteristics of hydrogen chloride (HCl) pollutants and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCCD/Fs). This study analyzed the influence of the materials ratio, incineration temperature, and additive volume of calcium oxide (CaO) on the emission characteristics of HCl and the dioxins. Results show that plastics in garbage are direct factors for the emission of HCl and PCCD/Fs. The HCl yield significantly increases when the plastic component ratio increases from 35% to 45%. The RDF containing 45% plastics releases the highest toxicity concentration of total dioxins, whereas the RDF of 35% plastics releases the lowest dioxin toxicity concentration. The optimal incineration temperature is 850 °C, the emission concentrations of HCl and PCCD/Fs are significantly reduced at 850 °C. Adding CaO to combustible solid waste can effectively reduce the emission concentrations of HCl and PCDD/Fs in flue gas.
