STOICISM presented in 17th IFAC Symposium on Control, Optimization and Automation in Mining, Mineral and Metal Processing in Vienna, Austria
As partner of the STOICISM consortium, Dr. Zakharov from University of Aalto, presented the contribution “Dynamic modelling of a multiple hearth furnace for kaolin calcination with a sensitivity analysis with respect to reaction rates” at the 17th IFAC Symposium on Control, Optimization and Automation in Mining, Mineral and Metal Processing in Vienna, (Austria). The platform presentation was devoted to the description of the dynamic modeling of a multiple hearth kaolin calciner. The physical-chemical phenomena taking place in the six furnace parts, including the solid phase, gas phase, walls, cooling air, rabble arms and the central shaft, are described within the model. A mixing model is developed to describe the solid phase movement, dividing the solid bed in a hearth into volumes and considering the distribution of their contents after one full central shaft rotation. Step changes are introduced to the feed rate to study the responses of the gas phase temperature and solid bed component profiles in the multiple hearth furnace (MHF). In addition, the sensitivity analysis of the temperature profile with respect to the reaction kinetics is also described.
International Federation of Automatic Control (IFAC), has the mission to promote the science and technology of automatic control for the benefit of industry and humankind. IFAC covers numerous technical areas, such as Process and Power Systems, while its technical committee on Mining, Mineral and Metal Processing supports research and development, education and technology transfer in all fields also addressed by the IFAC MMM Symposium. The IFAC MMM 2016 provides a forum for professionals, researchers, and experts in control, mining, mineral and metal processing to review state-of-the-art control, optimization, and automation technologies in the field.
