Similar models have been described by Fan and Rees. [1994], Zhou et al . Coal Pulverizer Mills Rebuilt or Replaced Chrome Carbide or .
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 take-up rate and they are also a regular cause of plant shut-down (Maffezzoni, 1986).
