Description:
The report gives results of an evaluation of the 1991-92 field performance of 11 woodburning stoves in and around Crested Butte, CO. Measurements included particulate matter (PM), carbon monoxide, total unburned hydrocarbons, and weekly average burn rates. The monitored stoves included catalytic and noncatalytic stoves, all EPA certified. The emphasis of this continuing study is to characterize the emissions from EPA-certified stoves as they age with normal use. Emissions from a previously monitored Phase II noncatalytic stove appeared to be unchanged when variations in fuel moisture content and burn rate were taken into account. A second Phase II noncatalytic stove also performed with emissions at levels which had been observed for noncatalytic in previous monitoring. On average, the catalytic stoves had PM emission factors about 59% greater than those measured during the 1989-90 study, when most of the monitored catalytic stoves had fresh catalysts. This increase is likely due to catalyst degradation. An average emission increase of 147% was measured for two Phase I catalytic stoves which were monitored in previous years. Two Phase II catalytic stoves, both of which were new this season, performed at the same emission level observed during the 1989-90 study of stoves with fresh catalysts.
