The report summarizes the results of a dioxin/furan emission test of a residential woodstove conducted by Radian Corporation. The stove is a freestanding noncatalytic model manufactured by Atlanta Stove Works and offered for sale in the Sear Catalog ($42G84156N). During testing oak and pine were burned at low burn rates, which is representative of normal residential use. The test was the 13th in a series of dioxin/furan emissions tests conducted under Tier 4 of the National Dioxin Study. The primary objective is to determine if various combustion sources 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. Residential woodstoves are among 8 combustion source categories that have been tested in the Tier 4 program. The tested woodstove, hereafter referred to as Woodstove WS-A, is a test unit located at an EPA contractor facility. This stove was selected for inclusion in the Tier 4 program due to its location in the RTP area and because simultaneous testing of the stove was already being conducted for another EPA program (Integrated Air Cancer Project). The woodstove tested is considered representative of woodstoves built in the last 5 to 10 years. No dioxin/furan stack data were obtained from the source. Labelled internal standards used to determine analytical recovery efficiency were not detected because of the very high levels of hydrocarbons present in the stack gas. Dioxin/furan ash data are presented.
