Mathematical modelling of roastng of calc-nepheline and cement mixture in tubular rotary kilns

Article preview

The article is devoted to developing a mathematical models of the sintering processes of calcnepheline and firing the cement mixture in a tubular rotary kilns based chain curtains. Chain curtains are installed in a rotary kilns for the intensification of heat exchange between the material and burn the gas flow, drying material, dust and carbon capture. The influence of chain curtains on the processes of heat transfer and dust separation are investigated. The developed equations allow to describe these processes in a mathematical model of a tubular rotary kiln. The resulting mathematical model of sintering and firing is implemented in software package ReactOp.

Chemical transformation kinetics at sintering of the shludge in tubular rotary kilns in alumina production

Article preview

This article is devoted to the  study of the kinetics and the development  of kinetic models of chemical reactions of minerals that occur during roasting and sintering of alumina in the tubular rotary kiln. To study the kinetics was used DSC firm NETSCH. Determination of kinetic constants and thermal effects of the individual stages were performed by solving the inverse problem in the environment of software system ReastOp. The experimental responses were used in sample mass change with time and heat speed (heat  absorption).
