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.

cement kilns. • In the 1950's, Harbison-Walker built a high-quality magnesite facility at Ludington, Michigan. This keyed the development of several industry standard products, including direct-bonded magnesite-chrome brick, pitch-bonded and pitch-impregnated magnesite products, and magnesite-carbon refractories. • In 1954, Harbison-Walker

The next common type of kiln is the vertical shaft kiln. This kiln can be described as an upright heavy steel cylinder lined with refractory material. The limestone is charged at the top and is calcined as it descends slowly to discharge at the bottom of the kiln. A primary advantage of vertical kilns over rotary kilns is the higher fuel ...

5 The earliest continuous kiln was the mixed feed vertical shaft kiln where the charge and fuel were blended together prior to feeding to the top of the kiln or fed as separate streams with mixing occurring on entry. These improved efficiency because the incoming limestone was preheated by the flue gas and the combustion air was preheated by cooling the lime.
