Abstract

Identification and control of precalciner in the cement production process with the increased use of alternative fuels is presented in this paper. The model of the system consists of the precalciner model as well as of pulverized coal transport model and alternative fuel transport model. The manipulated variable in the precalciner system is pulverized coal, while the alternative fuel calorific value change and the alternative fuel mass flow change are the main disturbances. Outputs of the precalciner model are the precalciner output gas temperature, as a controlled variable, and concentration of CO as measured variable. During the identification process, raw meal mass flow and primary secondary and tertiary air flows are considered to be constant. Based on identified model of the precalciner and the fuel transport model, the mixed logical dynamical controller is designed and implemented at Cement Factory Lukavac (Bosnia and Herzegovina). The mixed logical dynamical controller is realized on the cRIO 9014 real-time controller using LabVIEW (G) programming language. The real-time responses indicate improvements in precalciner temperature control while keeping reasonable low frequency and intensity of CO peaks.
