Detection of Malfunctions and Abnormal Working

The mill is one of six mills supplying the 650-k (steam production of 650 t/h) boiler. However, the proposed method in this chapter is so generic that it can be applied to other types of coal mills. The coal mill is illustrated in Figure 1 . The coal is fed to the coal mill through the central inlet pipe, where it is pulverized by a series
