Show incre~ses with temperature, incrR~ses with wast. chlorine ~ontent, ~an vary 5igni'i~antly with o~ygen concentration, and i5 strongly dependent on the type of Metal. Because increased metals vaporization leads to increased emission of metal-enriched flne parti~ulate M.tter, these effects &hould be taken into account in the deslgn, operation, regulation, and permitting of hazardous waste in~inerators and APC equipment. CONCLUSIONS This paper concludes that it is fea~ible to develop a theoretical model to predi~t the phenomenon of met~l partitioning during incineration. If the model can be verified by field test data, lt will have a wlde variety of applications. For e~ample, permit writers can use the model to estimate the accuracy of the data submitted by permit applicants and to decide what permit conditions should be 5pecified. Th~ model can also be used to examine the level of pretreatment required before a metal-bearing waste ~an be safely incinerated. It is likely that using a fully field validated Model to proJect the fate of trace metals in en in~ineration system will decrease permitting tiMe and cost ~ompared to the collection of field data on metals partitioning for every candidate incinerator.
