Coal Mill Operation. Fires or explosions most likely occur during startup and shutdown of a coal mill system. If a small amount of coal remains in the mill after it is shut down, it slowly increases in temperature. If the pulverized coal undergoes spontaneous heating and the coal mill is restarted with hot embers present, an explosion or fire ...

The coal milling operation is quite complex and nonlinear. It depends upon coal quality and milling conditions; apart from grinding it also involves heat transfer and modeling should include inertia terms [35]. Zhang et al. [3] developed a coal mill model for steady state operations and obtained the model coefficients using GA

The coal mill outlet temperature is an important monitoring variable during the operation of a coal mill and needs to be well controlled. Low outlet temperature indicates that the pulverized coal is not sufficiently dried, which will decrease the combustion efficiency of coal. However, extremely high outlet temperature will make explosions ...
