Formation, release and control of dioxins in cement

2008-1-1  The net formation and release of PCDD/PCDFs in cement production may therefore be due to a complex combination of simultaneous formation and decomposition reactions: • destruction of PCDD/PCDFs in the kiln region; • formation of PICs and chlorinated organics in the preheater, basically from raw material organics; •

Formation, release and control of dioxins in cement

It seems that the main factors stimulating formation of PCDD/PCDFs is the availability of organics in the raw material and the temperature of the air pollution control device. Feeding of materials containing elevated concentrations of organics as part of raw-material-mix should therefore be avoided and the exhaust gases should be cooled down quickly in long wet and long dry cement kilns without preheating.
