Special Issue Information

Dear Colleagues,

The study of the processes of ignition and combustion of woody biomass particles is a very important direction for the theory of combustion and is very important both from the point of view of applying the results of the study in real practice and from the standpoint of solving important problems of natural science. The latter is dictated by modern trends in the development of the energy sector, with the aim of the large-scale introduction of woody biomass into the overall balance of heat and power generation. Additionally, a deep understanding of the processes of ignition of wood will make it possible to predict forest fires with a high level of reliability and, accordingly, help to prevent them. However, despite extensive efforts in the development of this area of combustion theory, there are still many unsolved problems in the field of ignition and combustion of wood particles (for example, a unified theory of biomass pyrolysis and the combustion of thermal decomposition products has not yet been developed). This Special Issue is intended to provide an overview of the latest advances in thermal preparation, ignition and combustion of woody biomass under various thermal conditions. This Special Issue intends to provide selected materials that present advances in the science of woody biomass ignition.

Potential topics include, but are not limited to:

  • The ignition of wood particles;
  • Processes of thermal preparation of wood for combustion (drying);
  • Wood biomass pyrolysis processes;
  • Forest fires (occurrence and fire extinguishing issues);
  • Anthropogenic wood combustion products.

Thunderstorms are the main natural source of forest fires. The ignition mechanism of trees begins with the impact of cloud-to-ground lightning discharge. A common drawback of all predicting systems is that they ignore the physical mechanism of forest fire as a result of thunderstorm activity. The purpose of this article is to develop a physically based mathematical model for the ignition of a coniferous tree via cloud-to-ground lightning discharge, taking into account thermophysical, electrophysical, and physicochemical processes. The novelty of the article is explained by the development of an improved mathematical model for the ignition of coniferous trees via cloud-to-ground lightning discharge, taking into account the processes of soot formation caused by the thermal decomposition phase of dry organic matter. Mathematically, the process of tree ignition is described by a system of non-stationary nonlinear differential equations of heat conduction and diffusion. In this research, a locally one-dimensional method is used to solve three-dimensional partial differential equations. The finite difference method is used to solve one-dimensional heat conduction and diffusion equations. Difference analogues of the equations are solved using the marching method. To resolve nonlinearity, a simple iteration method is used. Temperature distributions in a structurally inhomogeneous trunk of a coniferous tree, as well as distributions of volume fractions of phases and concentrations of gas mixture components, are obtained. The conditions for tree trunk ignition under conditions of thunderstorm activity are determined. As a result, a complex three-dimensional mathematical model is developed, which makes it possible to identify the conditions for the ignition of a coniferous tree trunk via cloud-to-ground lightning discharge.
