The Deacon Reaction was proposed as a mechanism for the formation of molecular chlorine during the combustion of municipal solid waste (MSW): 4HCl + O2 ↔ 2Cl2 + 2H2O As suggested by some researchers, co-firing high sulfur coal with MSW may reduce the emission of toxic chlorinated organics, resulting from the reaction between S02 and Cl2: SO2 + Cl2 + H2O → SO3 + 2HCl The effect of sulfur dioxide on the formation of chlorine through the Deacon Reaction is investigated in this study. A Lindberg Furnace was utilized and preheated to 800°C to simulate the conditions in the AFBC system. The results indicated that S02 is an effective inhibitor for Cl2 formation. In addition, the optimum S/Cl ratio to reduce the toxic emission for co-firing is proposed. Tests regarding the AFBC system were also carried out to evaluate the combustion performance when co-firing coal with PVC pellets.
