Abstract

This paper describes a mathematical model for the calciner outlet temperature via regression analysis, aim to the outlet temperature control of calciner. Based on the analysis of cement production, we find the tertiary air temperature, coal feeding and raw material feeding may affect the calciner outlet temperature. Firstly, we provide a Single-Input and Single-Output (SISO) mathematical model and find it can reflect the calciner outlet temperature, but the fitted value is inaccurate. Secondly, we provide the Multiple-Input and Single-Output (MISO) mathematical model to obtain a more accurate fitting curve. Finally, the simulation results demonstrate the model with three inputs can reflect the calciner outlet temperature precisely.
