The report summarizes the results of a dioxin/furan emissions test of a drum and barrel reconditioning furnace equipped with an afterburner for emissions control. Steel drums are reconditioned by combusting the drum contents (residual material) in a tunnel furnace. The test was the 11th in a series of emission tests conducted under Tier 4 of the National Dioxin Study. The primary objective of Tier 4 is to determine if various combustion devices are sources of dioxin and/or furan emissions. If any of the combustion sources are found to emit dioxin or furan, the secondary objective of Tier 4 is to quantify these emissions. Drum reconditioning furnaces are one of 8 combustion device categories that have been tested in the Tier 4 program. The tested furnace, hereafter referred to as furnace DBR-A, was selected for the test after an initial information screening and a one-day pretest survey. The drums which are processed at the plant are received from a number of different sources, thus the combustible material burned in the furnace is heterogeneous. Furnace DBR-A is considered representative of other drum reconditioning furnaces operating in the United States. Data presented in the report include dioxin (tetra through octa homologue +2378 TCDD) and furan (tetra through octa homologue +2378 TCDF) results for both stack samples and ash samples. In addition, process data collected during sampling are also presented.
