Abstract
Stack gas analyses from a Norwegian cement kiln were performed during the incineration of hazardous waste. The kiln was operated by a dry cement process. Two studies carried out in 1983 and 1987 measured the emission of particles, organic micropollutants including PAH, PCB and PCDD, chlorine and heavy metals. Both studies concluded that the type of fuel incinerated does not influence the emission of organic micropollutants. The destruction of PCB was at least 99.9999%. The investigations show that the emission of particles, PAH and other cyclic organic hydrocarbons are more influenced by operation conditions than the fuel incinerated.
