In-home demonstration of the reduction of woodstove emissions from the use of densified logs
There is a need to reduce emissions from conventional wood stoves in the short-term while stove replacement takes place over the longer term. One possible is to use fuels that would burn cleaner than cordwood. Densified fuels have been commercially available for years and offer such a possibility. The objective of this project was to evaluate the emissions and efficiency performance of two commercially available densified log types in homes and compare their performance with cordwood. Researchers measured particulate matter (PM), carbon monoxide (CO), and volatile organic matter (VOC) emissions. Both total VOC and methane values are presented. Each home used an Automated Woodstove Emissions Sampler system, developed for the EPA and Bonneville Power Administration, in a series of four week-long tests for each stove. The sequence of tests in each stove was cordwood, Pres-to-Logs, Eco-Logs, and a second, confirming test using Pres-to-Logs. Results show an average reduction of 52% in PM grams per hour emissions overall for the nine stoves using Pres-to-Logs. All nine stoves displayed a reduction in PM emissions. CO emissions were more modestly reduced by 27%, and VOCs were reduced 39%. The emissions reduction percentage was similar for both types of stoves.
