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

The lime kiln is an important part of the recaust and recovery process in a mill. In the evaporation section of the kiln, chains which drag through the lime mud increase the drying area and evaporation rate of the kiln. Heat for the calcining reaction is supplied by a large burner at one end of the kiln. Training Time 26 minutes.

Lime Kiln Process presents one of the most challenging measurement and control solutions in the Pulp and Paper mills. The complex dynamics and multivariable nature of the lime kiln process, with its nonlinear reaction kinetics, long time delays and variable feed characteristics, make the process inherently difficult to operate efficiently.

Using a periodic lime kiln is generally more accurate than a heap kiln, but nonetheless is prone to some impurities and crosscontamination. One of the only ways to ensure a pure lime byproduct is to use a continuous lime kiln. Such a kiln is a standalone structure, but unlike its brick predecessors, it need not stand outside.

Using model predictive control allows the lime kiln to be operated as a unit instead of a collection of loops which all interact with one another. Since its an empirical model of the running processes it can predict into the future to help operators see where key variables are heading and help them resist manually intervening and inducing

Lime kiln dust is a very fine material having unique chemical properties of limestone and lime along with silicates and other inert materials, which make the lime kiln dust highly suitable in agricultural uses. Depending on the concentration calcium carbonate it has obtained from limematerial, lime kiln dust can be effectively used in soilliming process.
