This paper presents the results of an investigative study to determine the impact of leaching agricultural biomass on gaseous emissions and total suspended particles. Gaseous emission and total suspended particulates were measured in the stack of a domestic wood stove fired with leached and un-leached briquettes produced from commonly available agricultural biomass feedstock grown in Nova Scotia, Canada. The study primarily focuses on reducing gaseous and particulate emissions by leaching the biomass feedstock with water, prior to conversion and comparing against un-leached biomass feedstock. The result showed that the process of leaching significantly improved the fuel properties of the feedstock: however, a proportional reduction in gaseous and particulate matter emissions was not evident.
