20.500.12556/DKUM-96690 Synergistic effects of biomass and coal dust co-combustion on explosion safety The growing share of renewable energy sources in recent years has been driven by the development of national legislation in various countries aiming to reduce carbon dioxide emissions originating from fossil fuels. 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 combustion. biomass coal dust co-combustion dust explosion synergistic effects explosion pressure renewable energy safety engineering biomasa sinergijski učinki tlak eksplozije obnovljiva energija true false true Chair of Production Engineering (CPE), University of Maribor Faculty of Mechanical Engineering Angleški jezik Slovenski jezik https://apem-journal.org/ Članek v reviji 2026-01-23 12:34:59 2026-01-23 12:35:00 2026-01-24 03:11:34 0000-00-00 00:00:00 2025 0 0 str. 434-444 no. 4 Vol. 20 Dec. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-08-08 2025-12-07 2025-12-31 620.9 265904643 10.14743/apem2025.4.550 1854-6250 APEM20-4_434-444.pdf APEM20-4_434-444.pdf 1 01933CF5FC09C26F7CE53D6DBDB077C2 328db7cda3db8066979d75c6c7640681d0604d3fb91745b8f7e97416c9fc28a3 c4d9fc78-f84f-11f0-8c23-00155d00018d https://dk.um.si/Dokument.php?lang=slv&id=202490 https://apem-journal.org/Archives/2025/Abstract-APEM20-4_434-444.html 0 cad80274-f84f-11f0-8c23-00155d00018d https://dk.um.si/Dokument.php?lang=slv&id=202491 Fakulteta za strojništvo Advances in production engineering & management 0 0 0
