CHLORINATED ORGANIC-COMPOUNDS EVOLVED DURING THE COMBUSTION OF BLENDSOF REFUSE-DERIVED FUELS AND COALS

The objective of this study was to examine the possible formation of c hlorinated organic compounds during the combustion of blends of refuse derived fuels (RDF) and coal under conditions similar to those of an atmospheric fluidized bed combustion (AFBC) system. A series of experi ments were conducted using a TG interfaced to FTIR. Additional experim ents using a tube furnace preheated to AFBC operating temperatures wer e also conducted. The combustion products were cryogenically trapped a nd analyzed with a GC/MS system. The chlorination of phenols and the c ondensation reactions of chlorophenols were investigated in this study . A possible mechanism for the formation of chlorinated organic compou nds such as dibenzodioxins and dibenzofurans, by chlorination and cond ensation reactions involving phenols, was proposed.
