Abstract
The paper researches the process of heat and mass transfer in furnaces of the resistance in the silicon carbide production and considers a solid body with gas cavities and internal heat in general physical model of the process. Solid part is multicomponent and moist. The thermal conductivity with variable thermal parameters, variable porosity, the heat of chemical reactions, the process of drying the solid component, the generation of gas in chemical reactions and heat transfer seepage gas flow are taking into account. The mathematical description of the process is a system of two differential equations: the heat equation for a porous body with a chemically reactive components and heat transfer equation in the process of filtering the gas through the interconnected pores. Differential equations are supplemented by the necessary closing relations. Closing relations are the results of the considering of the processes model accompanying the silicon carbide production: the drying, calculating the pressure field in the system of interconnected pores, heat of chemical reactions and the effective thermal conductivity. The obtained mathematical model allows determining the temperature field, choosing variants of loading the furnace and regimes of melting in the silicon carbide production.
