Abstract
While operating a high temperature rotary calciner, two frequently encountered problems are shell overheating and the consequent deformation of the calciner, and heat loss. A simple and relatively inexpensive solution is to install a concentric metallic shield around the combustion zone. This heat shield can help to reduce the shell temperature and recover some of the energy that would otherwise be lost. Steady state temperature profiles of an industrial calciner with a heat shield around its combustion zone are computed via simulation. Open loop dynamics of the system are also analysed and the information obtained is used to design a PID feedback controller. Finally, the performance of the control system is tested with respect to various disturbances.
