Coal fired power plants are heavily used due to large and long lasting coal resources compared with oil or natural gas. An important bottleneck in the operation of this particular kind of plants, however, is the coal pulverization process, which gives rise to slow take-up rates and frequent plant shut-downs (Rees & Fan, 2003).In typical coal fired power plants, …

2. The hot air is used for transportation of the recirculating coal within the mill and also for transporting the coal from the pulverizer to the furnace. As the coal is continuously reduced in size, the smaller/lighter particles are swept from the bowl by the hot air. Hot air (and cool tempering air) is provided by the primary air fans.

Mill problems originate mainly due to poor controls or faults occurring within the milling system. As discussed by G.Q. Fan and N.W. Rees [3], the control of mills remains very simple in most of the power plants due to the fact that the mill system is highly nonlinear with strong coupling among the variables and it is very difficult to measure some important …
