The Study of Various Models of the Process of Thermal Treatment of Solid Waste

Resumo

Methods for calculating and modeling individual processes that occur during the thermal treatment of solid waste in reactors with constant and variable temperatures of the medium have been considered. Studies of the influence of various mathematical models of the heating of dispersed material on the results of kinetic analysis of the pyrolysis of wood waste have been carried out. The influence of the type of the mathematical model and its parameters on process characteristics have been shown. For the model of material heating that takes into account the change in the local temperature both with time and with coordinate, the dependences of the average nondimensional temperature of material of spherical and cylindrical form on nondimensional time have been proposed for different values of the Biot number.
