The purpose of this thesis is to create a model of the lime kiln that performs mass and energy balances over the process. This model is to be integrated in the WinGEMS software that is used to simulate mill systems in the pulping industry. There is an existing lime kiln block in WinGEMS but since has proven inadequate and in need of replacement.

Some shaft kilns can be operated on natural gas, liquid and solid fuels. This type of kiln tends to produce medium reactivity quicklime, which can then be used in a number of industrial processes including the manufacture of iron and steel and aerated concrete blocks. Quicklime from shaft kilns is also processed into hydrated lime.
