Anotācija The paper presents the results of experimental study of composition, heating values so as combustion and emission characteristics of a new type of plant biomass pellets, produced from non-hydrolyzed residues (LHRs) of different modes of spruce wood bioethanol processing. The small pilot-scale combustion system was used for experiments. The thermal decomposition of the biofuel and ignition of volatiles was initiated using the propane flame flow as additional heat source. The combustion conditions were optimized for different rates of the primary and secondary supply to obtain cleaner and more effective heat production with reduced impact on the global warming. The results were compared with those parameters for commercial softwood pellets. It was established that for equal total mass of fuel pellets (180g), equal rates of the additional heat supply into the biomass, the pellets from non-hydrolized residues could be gasified faster with more intensive heat release than wood pellets. It was established that LHRs produced by enzymatic hydrolysis of different configurations contain more sulphur and nitrogen than LHR produced by acid hydrolysis although the emission of SO2 did not exceed the domestic requirements. At the same time NOx emission exceeded the same requirements negligibly and conventional methods for NOx emission decreasing could be used. Keywords: combustion, bio-ethanol, non-hydrolyzed residues
