The paper presents results of the experimental study of composition, heating values and combustion characteristics of granulated non-hydrolyzed residues (LHR) of separated hydrolysis and fermentation (SHF) wheat straw bioethanol processing. The LHRs ash content at 1,4 – 1,7 times exceeds the values for the native wheat straw samples. It was established that higher heating values (HHV) of the granulated LHRs (on dry mass) exceed HHV of initial wheat straw and are some lower in comparison with that of softwood granules. Granulation was carried our using the laboratory scale flat die pellet mill KAHL. The higher plasticity of LHR results in lower energy consumption during the LHR granulation in comparison with softwood sawdust (most widely used for the production of biofuel granules). Due to higher thermolability of LHR, granules on its basis are characterized with faster gasification and faster transition to the active burning stage, but the average rate of heat release and total heat output are slightly lower to that for softwood granules. LHR obtained by enzymatic hydrolysis of wheat straw show the higher nitrogen content than native wheat straw and softwood, resulting in higher NOx emissions during the LHR combustion in comparison with softwood granules. Co-firing of LHR granules with propane flame, providing 10% of the additional heat supply into the combustor allows decreasing the levels of CO emission, so promoting cleaner combustion of LHR.
