Characterization of biomass emissions and potential

Jun 01, 2017 · Thus, modern small-scale pellet boilers do not only emit low amounts of OA, but also account for a low contribution to the total particle level in ambient air after atmospheric conversion processes. An estimation of SOA formation potential for BSP and BBP can be done by consideration of most contributing species to SOA formation (indicated by asterisk).
