Coal normally is available to power plants in large lumps ranging from 2 mm to 50 mm size. Coal is commercially available in different sizes known as "Run of Mine," "stoker," "slack," etc. depending on their size.
This study reviews issues related to the efficient and safe operation of coal pulverising systems for large power station boilers. Commercial considerations and the need to comply with increasingly stringent environmental regulations are challenging existing design and performance specifications for pulveriser systems. Pulverised fuel quality is critical in …

Wyoming Hanna Basin coal, Rosebud seam, having a heating value 9-13% below that of the original coal; analysis is shown in Figure 2. This fuel change did not affect Unit 5's load carrying capability. Then during 1983-84, OPP D began procurement of a significantly lower cost Wyoming Powder River Basin coal for their two coal-fired plants. This coal,
Hot air forced through the bottom of the pulverizing chamber removes unwanted moisture and transports the pulverized coal dust up through the top of the pulverizer and out the exhaust pipes directly to the burner. The more recent coal pulverizer designs are Vertical Roller Mills. Figure 2 shows a cutaway view of a Babcock and Wilcox MPS Pulverizer.
