Design of a heat shield and advanced control systems for a rotary calciner
Shell overheating and consequent heat loss are often encountered problems in the operation of a high temperature rotary calciner• Installation of a concentric metallic shield around the calciner provides a simple and relatively inexpensive solution to these problems. The heat shield can not only cool the shell but also recover most of the energy that otherwise would be lost. Substantial energy savings can therefore be realized. The success of such a shield in lowering the shell temperature of an industrial soda ash calciner is demonstrated by the way of computer simulation. The simulation has also been used to design a cascade control system and a feedforward control system for the calciner. The performance of these control systems is compared with that of the PID feedback control systems currently adopted in the plant. © 1993, Taylor & Francis Group, LLC. All rights reserved.
