This report presents the results of 19 emission tests on four wood stoves and two retrofit emission control devices. The testing was conducted during June-October 1981. The objectives of this study were to further identify the effect of wood moisture on stove emissions, to evaluate several inexpensive (simplified) test procedures for assessing particulate emissions, and to define a level of particulate emissions which can be expected from state-of-the-art improved combustion stoves. This study included evaluating previous test data reported in the literature. A single standard operating procedure was used throughout the test program, the objective of which was to maintain a constant heat output rate, as monitored by combustion chamber temperature and stove surface temperature. A heat output rate corresponding to a relatively moderate to low burn rate (less than 2.5 kg wood/hour) was chosen. A single wood type (Douglas fir) was used throughout the study, wood size was maintained at a consistent level. Throughout the entire test program measurements were made for particulates, carbon monoxide, carbon dioxide, oxygen, and hydrocarbon content of the emissions; the gaseous constituents were monitored continuously. Measurements were made for creosote deposition, opacity, and smoke spot density. Appendices for this report are contained in Report No. PB84-170646.
