Problems of heat and mass transfer on phase transformations or hemical reaction

This article review problems of kinetics of processes in a spherical particle under heat and mass transfer in conditions of chemical reaction or structural phase transformations. We use the approach of quasi-equilibrium to resolve kinetic equations. It is shown, that the suggested method simplifies the decision of this problem. For heat exchange and mass transfer processes with heat absorption, we received the closed system of the kinetic equations which can be investigated by numerical methods. Numerical calculations for a case of roasting of limestone particles are obtained.
