Abstract
This study investigates the effects of chlorides on the potential for hydrogen chloride (HCI) formation in a single heavy metal incineration system, using simulated municipal solid waste (MSW) with spiked organic and inorganic chlorides. The experiments were conducted at 900°C with the chlorine content varying from 0% to 1.6% (wlw as Cl The spiked chlorides include ionic and molecular bound compounds, such as PVC, C 2Cl 4, NaCl, KCI, and FeCl 3. The results indicate that an increase in the chlorine content enhances the potential for HCI formation in the flue gas and this potential is mainly affected by the characteristics of the chlorides, the presence of alkaline metals (Na and K) and the hydrogen content in the wastes.Furthermore, the HCI formation potential due to the presence of various organic and inorganic chlorides is found to be influenced in decreasing order as: PVC, C 2Cl 4, FeC1 3, NaCl, and KCI. The consistence is confirmed between the above experimental results and model predictions based on thermodynamic equilibrium analysis.
