Field Performance of Woodburning Stoves in Colorado During the 1995-96 Heating Season

During the winter of 1995-96, the field performance of 13 EPA-certified woodburning stoves in Crested Butte and Curecanti National Park, CO, was evaluated. Measurements included particulate matter (PM), carbon monoxide (CO), and weekly average burn rates. Six non-catalytic Phase II stoves, six catalytic Phase II stoves, and one catalytic Phase I stove were monitored. The study adds to the existing database on the field emissions of newer and older certified stoves. Average non-catalytic stove PM and CO emission factors of the study were 9.8 and 93 g/kg, respectively. For the catalytic stoves the factors were 22.8 and 112 g/kg, respectively. The report compares these values with results from previous studies and suggests reasons that field performance is poor relative to what might be expected from certification test results. This Project Summary was developed by the National Risk Management Research Laboratory’s Air Pollution Prevention Control Division, Research Triangle Park, NC, to announce key findings of the research project that is fully documented in a separate report of the same title (see Project Report ordering information at back).
