Clinker: Fly ash from coal-fired power plants can be used effectively as a component of raw kiln feed for the manufacture of cement clinker. Fly ash contains significant amounts of Al 2 O 3 and SiO 2 and has thus been used as a partial replacement of natural raw materials like clay and/or shale in the raw kiln feed.
The coal flow into the mill is only indirectly mea- surable. Implying that the early fault detection based on detection of drops in the coal flow of the coal mill, is not so simple as it seems. A critical example on a fault in the coal mill is caused by a blocking in the raw coal inlet pipe, a coal mill is illustrated in Fig. 1.
