Modeling, Control and Instrumentation of Lime Kiln Process: A Review

Present paper attempts to review the literature related to various strategies to design the control system for the Lime kiln industrial process. Lime Kiln is multivariable process with complex interactions of variables. It has higher degree of coupling, severe non linearities, and frequent disturbances. This paper covers the modeling and control aspects of Lime Kiln process. The lime kiln control in recovery section of paper mill along with heat and mass transfer in reaction, radiation, and convection in limekiln is also presented. This paper also explores the possibilities of improving the control of the lime kiln by reviewing the literature of various control techniques including both the conventional and the modern ones.
