Special Issue Information

Dear Colleagues,

It is with pleasure that we invite you to contribute to this Special Issue with papers on the subject of dust explosions in the process industry. We know how this topic is both current and transversal to practically all productive realities and how even serious explosions continue to happen, causing huge losses. We all know well how the efforts made in studying the causes and consequences of dust explosions have brought great benefits to the process industry, but we also know that much work remains to be done.

New challenges arise continuously, for example, with the advent of nanopowders, while further investigation is required in the field of unconventional powders, such as fibrous and flocculent dust. Moreover, new technologies, including 3D printing and the use of biomass granular material to generate energy, make extensive use of powders and are likely to contribute to creating new risks related to dust explosions.

We hope that you would like to contribute to this Special Issue. Submissions on the following topics, among others, are welcome:

  • Case studies;
  • Non-conventional dust;
  • New technologies;
  • Dust parameter measurement methods;
  • Ignition phenomena;
  • Flame speed;
  • Turbulence effect;
  • Numerical modeling;
  • New experimental methods;
  • Dust mixtures.

The concern about global warming issues and their consequences is more relevant than ever, and the H2020 objectives promoted by the EU are oriented towards generating climate actions and sustainable development. The energy sector constitutes a difficult challenge as it plays a key role in the global warming impact. Its decarbonization is a crucial factor, and significant efforts are needed to find efficient alternatives to fossil fuels in heating/electricity generation. The biomass energy industry could have a contribution to make in the shift to renewable sources; the quest for a suitable material is basically focused on the energy amount that it stores, its availability, logistical considerations, and safety issues. This work deals with the characterization of a wine-waste dust sample, in terms of its chemical composition, fire behavior, and explosion violence. This material could be efficiently used in energy generation (via direct burning as pellets), but scarce information is present in terms of the fire and explosion hazards when it is pulverized. In the following, the material is analyzed through different techniques in order to clearly understand its ignition sensitivity and fire effects; accelerating aging treatment is also used to simulate the sample storage life and determine the ways in which this affects its flammability and likelihood of explosion.

Mathematical Modeling of Coal Dust Screening by Means of Sieve Analysis and Coal Dust Combustion Based on New Methods of Piece-Linear Function Approximation

This study focuses on the development of new methodological approaches to dust-preparation and burning of separated particles, including through the use of polyfractional ensembles. Coal dust screening by means of sieve analysis is described in standard methods. However, in order to further use the results obtained during mathematical modeling of particle motion in fuel-air mixture and exothermal reactions of oxidation while burning in a torch, it must be possible to differentiate and integrate continuous functions. The methodology is based on the continuity of particle motion in a mixture with air in the calculation of aerodynamic and heat-mass exchange processes in a torch. The paper employs new scientific approaches to transforming and normalizing a continuously differentiable function described by the Gauss curve. We propose to combine mathematical modeling of such functions with methods of approximation of piece-linear functions developed by Professor S. V. Aliukov. The implementation of such methods helps reduce calculation errors of particle size and deviations thereof from average equivalent diameter and to avoid the Gibbs effect while differentiating. The paper contains analytical calculations based on the proposed method and experimental data. Quantitative and qualitative results of comparing analytical and experimental data are also presented. We provide recommendations on the further use and extension of the range of the results obtained in a computer simulation of fuel production and burning processes in a torch. Full article
