Kanso V. Design and intensification of the processes of thermal decomposition of dispersion carbonate of calcium in the revolved stoves

Object - process of thermal dissociation of dispersible calcareous waste in a rotating furnace. A subject - a single particle, a layer of a dispersible material and movement of a layer on furnaces, physical and mathematical models of process of thermal dissociation of a mobile material, kinetics and dynamics of process of furnacing. Methods - in work are used methods of physical and mathematical modelling of process of thermal dissociation of a dispersible material in a rotating furnace. Theoretical and practical results - are received analytical dependences which represent mathematical model of process of furnacing, have enabled to carry out predicted calculations of rational technological process conditions of furnacing and, accordingly, to finish economic feasibility of recikling process calcareous waste; improvement of a design of the furnace and the technological process flow diagram which provide realization of rational duties and management with them is lead. Novelty - is offered mathematical model which describes character of mixing and movement of a burnt out dispersible material along the furnace; it is positioned, that the criterion of quality of mixing of a material is factor of heterogeneity of a mobile layer, is positioned, that criterion of efficiency of process of pelletising - the distribution function of granules on the size and residence time in the furnace; The mathematical model of processes of drying, the thermal schedule of a dispersible material and sintering of products of the schedule which adequately describes all stages of process is developed. A degree of introduction - trial tests. Area - chemical mechanical engineering
