Pulverised Coal Combustion - an overview ScienceDirect ...

Pulverized coal (PC) combustion is presently the system of choice for coal-fired power-generating plants. 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 ...
