Abstract:To improve the safety and economy of coal mill operation, a dynamic mathematical model was established for MPS medium speed coal mill based on mass and energy balance. Considering the impact of coal moisture on the energy balance and taking the pulverized coal moisture as a state output, the model parameters were identified with ...

According to the mechanism model, the moving horizon estimation method was used to estimate the outlet flow of the coal mill, and subsequently the estimated results were compared with model outputs. Based on analysis of the disadvantages existing in the control system of present medium-speed coal mills, an inferential predictive controller was ...
