Coal Milling Operational Constraints

Coal Milling Operational Constraints

Coal Mill - an overview ScienceDirect Topics

Operating data from a coal mill is used to compare the fault detection observer-based method and PCA/PLS models based approach. There are 13 process measurements available representing different temperature, mass flows, pressures, speed etc in the coal mill. The measurement is not updated, if the variation is less than 1%.
