Sustainable growth of national economies therefore requires the search for novel green technologies. Biomass has recently been used as a supplementary fuel to coal. The literature describes the synergetic effect in the technical context of combustion in the power engineering sector. In the presented research, five types of biomass dust were added to coal dust. The selected explosion indices were determined using a 20 L sphere apparatus, in accordance with EN 14034 standards. The results demonstrate the impact of biomass on the course of dust–air explosions. A synergetic effect was observed and explained. Certain types of biomass were found to be characterized by a higher explosion pressure rise (15-17 % or 0.88-1.28 bar) and higher maximum explosion pressure rates (16-148 % or 57-143 bar/s) than those obtained for the samples tested separately. The results indicate that the implementation of biomass for co-combustion always requires a revision of the existing process safety measures designed for coal combustionTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Mariboru, Fakulteta za strojništvo
