Abstract

The results of numerical studies of aerodynamics of the dense layer and hollow regions of the shaft kiln; mechanism of material movement; kinetics of lump limestone dissociation are presented. A mathematical model of a shaft kiln with distributed parameters is developed. A computer program allowing to carry out predictive calculations of firing and to optimize mode and determining geometrical parameters of the installation is made. Proposals for modernization of operating shaft furnaces are made.
