By burning the coal of relatively high heating value the boiler can achieve its MCR by operating only 3 pulverisers. For NCV = 25 MJ/kg the coal price was assumed according to [31] at the amount of 323.00 PLN/Mg. Respective results are presented in Figure 17. Higher price of coal increases the total cost of boiler operation.

sized pulverizer throat will require more than optimum primary air-flow to minimize coal rejects. The pulverizer "free annular jet" of vertically flowing airflow, in our experience, must be adjusted for a minimum of 7,000 fpm under normal operation. Throats that are oversized will result in either excessive coal rejects (not tramp metal

Raw coal is conveyed from the storehouse by a belt conveyer. Then it is lifted to the entrance level of a vertical cylindrical mill by a bucket elevator, and an electromagnet is used to remove iron objects from the raw coal. The raw coal is pulverized in the vertical cylindrical mill, and the pulverized coal is lifted to a powder separator by

coal pulverizer systems supplied by RPI originally designed for low, medium and high- speed pulverization have undergone design upgrades and improvements. These machines include Ball Tube Mills (BTM), MPS mills and Atrita@ Pulverizers, respectively. The Atrita@Pulverizer has been upgraded for better coal fineness and longer service life. BTM

In PC combustion, the coal is dried and is ground to a specified fineness, with a maximum particle size of 250–300 μm, depending on the reactivity of the coal. Coal preparation, which involves feeding, drying, and grinding of the coal, and the pneumatic transport of the pulverized coal to the burners, is fully integrated with the boiler.
