On-line measurement of coal quality parameters by inference of sensor information

Objective

Ash and moisture content of the coal and its handle-ability are important quality parameters.

To maintain high standards it is essential to get knowledge of key parameters throughout the whole preparation process. There are few measuring instruments because they are expensive and need much maintenance. On the other hand many signals from different sensors are available which contain inherent information about single product streams.

By an intelligent data processing system quality parameters can be inferred from a combination of signals. For the inference of handle-ability the size distribution is a key parameter, for which sensors have yet to be developed. Also for the subsequent utilisation in power plants the size distribution is very important. For a continuous optimisation of the pulverised fuel preparation on-line measuring devices have to be integrated into the milling circuit.
