The report gives results of a literature search of 53 reports covering woodstove design, operating conditions, emissions, testing methods, and ambient air impacts. The woodstoves studied, both controlled (catalytic) and uncontrolled, varied in design from simple to complex. The primary considerations in operating conditions were that the stoves burned primarily cord wood. Test results were segregated by the type of wood utilized, the percent moisture in the tested wood, the burn rate of the wood, the stage of burning that was tested, and the length of the test. In addition to the operating conditions, the emissions were qualified by the test method that was performed, the firebox temperature, and the stack temperature. Emission parameters studied included particulate matter (PM), carbon monoxide, nitrogen oxides, hydrocarbons (HC), and polycyclic organic material, especially benzo-a-pyrene. This report includes ambient air impact surveys at various locations in the U.S. Most ambient studies were concerned with the PM and HC impacts, but a few looked at relating these impacts back to their sources.
