Abstract

This article presents results of a laboratory-based investigation of the use of four common household furnace filters to reduce emissions of PM 2.5 from a forced draft side feed biomass cook stove burning sticks of Douglas fir. The total emissions, from the chimney and fugitive, were pulled through 20” x 25” x 1” household furnace filters to capture the particulate matter before the air and gases exited the enclosure surrounding the stove. A box fan pulled the air and PM 2.5 through the filters. The stove and filters were tested under the Laboratory Emissions Monitoring System (LEMS) with gravimetric measurement of PM 2.5 during the cold start high and low power phases of the Water Boiling Test 4.2.4. The average of seven baseline emissions tests of PM 2.5 was 7.5 mg/min. The average of seven tests using the highest quality furnace filter (3M 2200) was 1.5 mg/min. The use of retained heat to simmer also dramatically reduced fuel use and emissions. An average of 256 grams of wood was consumed to boil 5 liters of water and to simmer the remaining water for 35 minutes.
