coal mill model control
Modelling and control of pulverised fuel coal mills ...
An area of power plant control that has received much less attention from mod elling and control specialists is the coal mills. This is in spite of the fact that it is now accepted that coal mills and their poor dynamic response are major factors in the slow load takeup rate and they are also a regular cause of plant shutdown (Maffezzoni, 1986).

Modeling and control of ball mill system considering coal ...
This study analyzes the dynamic characteristics of duplex inlet and outlet ball mill direct firing pulverizing system. A mass and energy balancebased model is built by thermodynamic analysis. As a critical parameter in pulverized coal humidity control, coal moisture is considered in the mechanism model, and an extended Kalman filter is designed to estimate the coal moisture.

This paper presents a solution for the detection and control of coal loads that is more accurate and convenient than those currently used. To date, no research has addressed the use of a grinding medium as the controlled parameter. To improve the accuracy of the coal load detection based on the kinetic energy of balls in a tubular ball mill, a Discrete Element Method (DEM) model for ball ...
