Simulation mathematical model for granular material thermal treatment

Abstract

In the last years new technologies in the area of granular materials thermal treatment have been developed. Basic improvement was achieved in significant increasing of heat exchange area, heat distribution and in the hydrodynamics. Development and operation of this thermal apparatus is based on physical and mathematical modelling, which can significantly contribute to acquire required critical knowledge. For lumpy and granular material thermal treatment the approximate mathematical model based on elementary balance method was developed. Model adequacy and complexity is crucial part of generation of the effective VR system. One of the possibilities to master this difficulty is generation of the hierarchical simulation models. Presented system consists of the following discriminations levels: Production line, technological aggregate, aggregate components, processes. The production line is of granular materials thermal treatment. Regarded technological aggregates are rotary furnace, shaft furnace, microfluid furnace and the furnace in compact thin layer. The modelled processes are gas flow, material flow, combustion, heating, cooling, drying, condensation, calcinations and sintering. Models are part of the developed VR system.
