The cement rotary kiln is a time-varying, non-linear parameter system whose non-linear and dynamic behavior leads to its chemical interactions. At the beginning of the industrial production of cement, furnaces similar to brick kilns and lime kilns were used. In this field, a lot of energy was used and a lot of manpower was used.

Rotary kilns have been important for decades as calciners for various processes, especially cement production. More recently, rotary kilns have been adopted as an effective means for the incineration of hazardous wastes. This is par-ticularly true of solid hazardous wastes such as sludges, sorbents, and contaminated soils. Rotary kilns are able to

Vapour Pressure. The equilibrium vapour pressure for compounds of volatile components is seen in Figure 4.11 as a function of the temperature. Recalling the principle of vapour pressure curves, the equilibrium vapour pressure of a component is the partial pressure exerted by the components gas phase when the liquid phase and gas phase are in equilibrium.
