“…Similar conclusions were presented by Bajcar et al [29]. Many researchers suggest that these changes may be linked to differences in emissivity of the specific materials as well as the shape and size of the specific particles [35,37,55,66]. Studies by Dobashi et al and Yuan et al [48,67] demonstrated a significant correlation between Pmax and a decrease in particle size.…”

Because of the current energy crisis, researchers are looking into new potential substrates for production of biofuels and for possible ways to enhance their parameters. In line with such efforts, the current study focuses on the feasibility of processing waste from the production of cultivated tobacco. The aim of this study was to assess the potential of tobacco waste as a raw material for the production of solid biofuels, such as biochar produced through pyrolysis, and to determine its basic physicochemical properties, compared to other materials used for the production of green fuels. The analyses showed calorific values of 16.16 MJ kg−1 for the raw biomass and those in the range of 24.16–27.32 MJ kg−1 for the products of pyrolysis conducted at temperatures of 400–500 °C and with a heating time in the range of 5 to 15 min. To address the safety-related issues, the study also measured the explosion index (Kst max), which, in the raw biomass, amounted to 72.62 bar s−1 and in the biochar was in the range between 82.42 and 88.11 bar s−1. The registered maximum explosion pressure was 7.37 bar in the case of raw biomass, whereas in the biochars, the value ranged from 8.09 to 8.94 bar. The findings show that tobacco waste has parameters comparable to those identified in the case of other solid biofuels, whereas the process of pyrolysis enhances the energy-related parameters without increasing the explosion class of the product.

“…The hazards that increase the risk of ignition include contact of dust with hot air, heated components such as engines and moving parts of machinery. In the case of lignocellulosic biomass, important risk factors include electrostatic discharges, which occur during mechanical processing, transport and storage of the biomass [37][38][39].…”

“…Similarly, the use of modelling, although potentially associated to an appropriate and relevant response, could not be successful without preliminary testing. For instance, Islas et al [1] proposed a three-layer method to study biomass dust explosions: by merging the CFD simulation of the dispersion process, ignition and flame propagation steps, experimental tests and general knowledge of the chemical mechanisms involved, it is possible to deepen the conclusions that may be drawn from an explosion experiment.…”
