Production of lime requires burning the limestone at controlled, high temperature in a rotary kiln. Temperature measurement at key locations during operation of a kiln is important to maintain an optimum performance to minimise downtime. VisionTIR offers different solutions to prevent damage to the kiln shell and ensure product quality.

Given the long process delays and variable interaction inherent to lime kilns, these objectives are extremely difficult to achieve under manual or standard closedloop kiln operation. A predictive control algorithm, MACS TM Multivariable Advanced Control System has been successfully applied to a Scandinavian kiln.

LimeLine lime kilns but also effective energy conservation and emissions control. The lime kiln is a huge consumer of energy in a pulp mill, and a large potential generator of CO 2 emissions. Energy and emissions need to be adequately controlled to consistently produce highquality lime for cooking liquors.

A lime kiln is a kiln used for the calcination of limestone calcium carbonate to produce the form of lime called quicklime calcium oxide.The chemical equation for this reaction is . CaCO 3 heat CaO CO 2. This reaction takes place at 900 C 1,650 F at which temperature the partial pressure of CO 2 is 1 atmosphere, but a temperature around 1000 C 1800 F at which
