Abstract |
A series of pilot-scale incineration tests was performed at the EPA's Incineration Research Facility (IRF) to evaluate whether increased emissions of regulated pollutants could occur when an incinerator's automatic waste feed cutoff (WFCO) system repeatedly stops waste feed to the incinerator. Test program results show that none of the tested incinerator operating modes caused significant increased POHC, trace metal, or HCl emissions. POHC destruction and removal efficiencies (DREs) for all repeated WFCO tests were within the range measured for the two baseline tests. Similarly, trace metal emission rates and distributions among incinerator discharges for all repeated WFCO tests could not be differentiated from the baseline tests. Overall, test results suggest that the permit requirement to terminate waste feed whenever a permit-specified operating limit is exceeded apparently prevents significantly increased incinerator emissions of POHCs, trace metals, and HCl; particulate emissions can increase, however. |
