Model of the transient operation of a coal pulverizer ...

The model was developed primarily for predicting the influence of a pulverizer on an associated coal-fired boiler. The model is based on a set of 76 ordinary differential equations that govern conservation of coal mass in six internal regions of a pulverizer and in 15 particle-size groups. Subsidiary equations describe the internal coal flow rates.
