  • Coal Mill Modeling for Monitoring and Control

    Sep 2, 2011 COAL MILL MODELING. The MPC controller for coal mills is based on a nonlinear physical model to describe the grinding, drying, and sepa ration processes occurring in typical coal mill pulverizers. Similar models have been described by Fan and Rees. [1994], Zhou et al. [2000] and Niemczyk et al.

    Also, hard inclusions in the coal, such as pyrites or rock, may be a source. The action of these materials against one another or moving parts in the mill may produce sufficient heat and sparks to initiate a fire or an explosion. Broken damper plates or fan blades from fans or ducting may also create frictional sparks which can
