Optimal control of annealing during the preparation of aluminum hydroxide and cement clinker in tubular rotary kilns

Abstract

A mathematical model of the preparation of aluminium hydroxide and Portland cement in tubular rotary kilns has been developed. Experimental data have been obtained by TG DSC on a NETCH calorimeter; mathematical models of reactors have been obtained based on an analysis of the motion of multiphase systems. The models of reactors have been used to solve the problems of optimizing the temperature profile in apparatuses using technological criteria of optimization by nonlinear programming methods.
