Cement Raw Material Feeding Amount Filtering Method Based on Kalman Filter

Abstract

The stable thermal system of the cement kiln system is an important guarantee for realizing the stability, high quality, high yield and low cost operation of the new dry process cement kiln. In order to ensure the stability of the thermal system of the kiln system, it is necessary to accurately estimate the true value of the raw material feed amount. In this paper, the filtering method of raw material feeding amount based on Kalman filter was studied. Firstly, the cement clinker production process and the Kalman filter principle are analyzed. On this basis, for the specific situation of raw material feeding amount, the raw material feeding amount filtering process based on the Kalman filter was proposed. Finally, the method was verified by data analysis. The data analysis results show that the Kalman filter algorithm could realize the online accurate estimation of the raw material feeding amount. This paper provided a feasible method for filtering the raw material feeding amount of cement.
