Biomass is considered as one of the most promising fuels worldwide, mostly because its renewability and almost-neutral carbon balance. At same time, numerous studies have shown that combustion biomass results in emissions multiple gaseous particle phase pollutants. The aim this study was to fill gap data from agricultural fuels. Five residue-derived were tested: sunflower stalk pellets, straw buckwheat shells, corn wheat grain screenings. In addition, wood sewage sludge pellets investigated reference Experiments performed a commercially available domestic 13 kW pellet burner during optimal stable conditions. characterization basic pollutants (CO, CO2, SO2, NOx), well specific (size-segregated particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), BTEX (benzene, toluene, ethylbenzene, xylenes) conducted. PM represented by PM1 fraction (PM1/TSP > 0.8) case all Total ranged 0.28 g/kg 5.23 g/kg. PAHs 469.4 μg/kg 7212.2 μg/kg. Size-segregated PAH analysis revealed detected fine aerosol (0.056–0.18 μm). Sewage determined polluting fuel, including emissions. Several fuels, found be least favorable for small-scale pellet-type burner, increased CO PAHs.
