| Shrnutí: | Title screen The effect of the kinetic model of the thermal decomposition of wood on the results of prognostic modeling of the ignition of wood particles was analyzed. The results of mathematical modeling were verified by experimental studies of the ignition of wood particles in a high-temperature environment. Comparative analysis of theoretical and experimental ignition delays shows that they are in good agreement. The prognostic potential of three substantially different kinetic models of wood pyrolysis was analyzed. The model of one-step pyrolysis involving the formation of gaseous reaction products adequately describes thermal decomposition during thermal preparation in the whole range of heating conditions (the deviation from the times obtained using the three-step pyrolysis model does not exceed 5%). Numerical simulation results show that accounting for the thermal decomposition reactions of the second and third levels with the formation of intermediate (liquid and solid) pyrolysis products does not have a significant influence on the characteristics and conditions of ignition of wood particles in a high-temperature gas environment.
