Dioxin reduction by sulfur component addition

Abstract Dioxin (PCDD + PCDF) reduction test by sulfur component addition was carried out using small scale FBC (Fluidized Bed Combustorr) test system. Sulfur sources were three different modes; CASE A: gaseous SO 2 was directly fed; CASE B: coal containing sulfur was fed; CASE C: coal + sulfur reagent were fed. Dioxin reduction occurred for each case and coal addition was so effective for dioxin reduction. It is thought that this effect results from Cl 2 reduction which was caused by gaseous SO 2 in the flue gas.
