Characterization of the explosiveness of wood dust Santamaria Herrera, Alba Hoyuelos Álvaro, Fco. Javier Casado Marcos, Carlos Explosion characteristics Sawdust Biomass dust Explosive atmospheres Minimum ignition temperature Factors that influence the explosiveness of wood dust, like particle size distribution, moisture content and microscopic structure, have been characterised. Sawdust flammability has been tested in a Hartmann tube. The Minimum Explosive Concentration and Minimum Ignition Temperature of dust clouds and layers have also been measured. Dust granulometry linked to the regularity of its structure and moisture are the essential parameters to generate or not an explosive atmosphere. Smaller particle size dust with a lower moisture content is much more likely to create an ignition and/or explosion risk. The samples have been classified into two groups, those collected from cutting processes and those found in the ventilation ducts or deposited in the facilities. The most dangerous samples are those from Group 2. In some cases, dust samples up to 35 % moisture or with particle size greater than 500 µm at maximum dryness are able to produce an explosion. 2023-03-02T11:38:09Z 2023-03-02T11:38:09Z 2023-01 info:eu-repo/semantics/article 0957-5820 http://hdl.handle.net/10259/7484 10.1016/j.psep.2022.10.087 eng Process Safety and Environmental Protection. 2023, V. 169, p. 252-259 https://doi.org/10.1016/j.psep.2022.10.087 http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier
