intelligent control system of the lime kiln
ADVANCED LIME KILN CONTROL OPERATING RESULTS FROM A
The main process objective of lime kiln operation is to produce a uniform quality lime. Additional operating objectives include minimizing fuel consumption and complying with environmental regulations. Given the long process delays and variable interaction inherent to lime kilns these objectives are extremely difficult to achieve under manual or standard closed-loop kiln operation.
