Abstract
ABSTRACT
The USEPA Combustion Research Facility incinerator has been challenged in a series of experiments using toluene solutions of hexachlorobenzene (HCB) in which the HCB input and stack emission rates were determined. The resulting destruction and removal efficiency (DRE) was found to be in excess of the required 99.99%. On the other hand emissions of HCB were found even in the absence of feed. Sampling the combustion gases in the exit duct of both the kiln and the afterburner led to the conclusion that these emissions originate from the hot zones as well as from the air pollution control system. In addition, evidence is presented suggesting that the destruction efficiency of the afterburner at lower feed rates may depend directly on the feed rate of HCB to that chamber. Presumptive evidence is presented for the formation of and the identity of Products of Incomplete Combustion (PICs).
