Mill performance could be indicated by the mill outputs, and problems could be predicted and even avoided by good control strategies of nonlinear systems [25]. Thus, research works have been devoted to the control optimization and fault diagnosis of coal mill [536], in which accurate modeling of coal mill is an essential work.

The bowl mills are further divided into deep bowl or shallow bowl mills. • Impact mill: These are highspeed impact machines that use beater wheels to crush the coal. Ball Tube Mills Tube mills: The tube mills are lowspeed machines that grind the coal with steel balls in a rotating horizontal cylinder. If the length of the cylinder is ...

Pulverized coal is the most efficient way of using coal in a steam generator. The coal is ground so that about 70 % will pass through 200 mesh ( mm) and 99 % will pass through 50 mesh ( mm). A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty.

Knowledge of moisture content in raw coal feed to a power plant coal mill is of importance for efficient operation of the mill. The moisture is commonly measured approximately once a day using offline chemical analysis methods; however, it would be advantageous for the dynamic operation of the plant if an online estimate were available.

As mentioned in Section 1, the change of coal in a thermal power plant typically happens over a period of several hours (referred to as coal transition) and there is an irregular time lag between the coal change at the bunker level and that at the mill or boiler level (Tuttle et al., 2020). Therefore, realtime detection of change of coal in an ...
