Abstract
Chlorinated aromatic compounds are unintentionally released from combustion
sources into the environment. This thermal formation is catalyzed by fly ash
components and much interest has been focussed on the role of copper. This study
report results from a series of 16 full-scale trials with different fuel
compositions. The correlation pattern of fly ash components seem to suggest that
the catalytic effect may be due also to other metal oxychlorination catalysts.
Chromium shows particularly strong and statistically significant correlations
with many of the chlorinated phenols, benzenes, dibenzo-p-dioxins (PCDDs),
and dibenzofurans (PCDFs).
