Abstract
The mathematical description of the technology of firing of lump limestone raw materials in a shaft kiln equipped with burner devices providing preliminary gas combustion is given. The model takes into account the peculiarities of the process of dissociation of carbonate component of raw materials, uses equations describing the kinetics of the drying process, conditions of counter-flow of gases and material, regularities of distribution of material and gas flows along the cross-section and height of the shaft. The developed model represents a stationary two-dimensional solution of the problem.
