Particulate emissions from a modern wood stove – Influence of KCl

Particulate matter (PM) generated by residential wood combustion is a major environmental concern in Europe. This study focuses on the influence of potassium chloride (KCl) fine particle emissions from modern stove. Wood logs with and without KCl impregnation were subjected to batch emission measurements. A bi-modal number-size distribution characterized nucleation mode an accumulation was identified for all types fuel. However, presence KCl, lower number ultrafine particles higher larger (size ∼200–500 nm) observed. In addition, factor condensed organic compounds (COC) increased increasing content, 0.16 g/kg dry normal (NW) 0.48 impregnated 2 mol/L solution (HKW), most likely due facilitated heterogeneous condensation semi-volatile hydrocarbons pre-existing ash particles. soot also slightly when content high, 1.47 NW 2.23 HKW.
