[Subject] To provide a cement manufacturing apparatus and the like capable of increasing quantity of fly ash used in the apparatus while controlling unburned carbon content in cement within a permissible range. [Means for Solution] The cement manufacturing apparatus and the like comprises a removal means for removing unburned carbon from gypsum, and a grinding means for grinding gypsum from which unburned carbon is removed by the removal means together with clinker to generate cement. With the apparatus, total unburned carbon content in cement can be reduced, and the quantity of fly ash used in the apparatus can be increased by the reduced amount of unburned carbon. The removal means can remove unburned carbon contained in gypsum as well as unburned carbon contained in fly ash, and the grinding means may grind the fly ash from which unburned carbon is removed together with the gypsum, from which unburned carbon is removed, and clinker. The removal means may simultaneously remove unburned carbon contained in gypsum and unburned carbon contained in fly ash. |

This object is achieved using an existing water injecting technology used in precalciners for NOx control. The inventive method comprises the step of injecting water into the precalciner to control the temperature. Thanks to considerably different time horizons of the NOx control on one side and the temperature control on the other side, the two objectives can be achieved in parallel. The short term variations on the water injection for temperature control purposes are superposed to the long term water injections necessary to provide appropriate NOx control.

Dual estimation and a parameterized model of the circulation of volatiles is used to identify the changing volatility parameters (E1, E2, A) in a cement kiln and to estimate the concentration of the volatiles; the estimates of the volatility parameters will then be used to predict the evolution of the volatile concentration over time. The inventive method can be applied in a computer based simulation of the cement kiln. Model predictive control and mixed-integer programming are used to optimize cement production. The module predicts the evolution over time of the concentration of volatile components, a quantity which is used in the mixed-integer program solved in each optimization.
