Give your plant a dust control tune-up Because PRB coal is smaller, more friable, and contains more fine particulates than bituminous coal, controlling the fugitive dust generated as PRB coal moves from bunker to burner tip is problematic.

Dust-collection systems capture fugitive coal dust that would otherwise escape from the perimeter of equipment areas. Collected fugitive dust is fuel that should be delivered to the furnace and burned. Dust control systems come in many different area-specific configurations (Figure 1). In the typical power plant, they can be found between the coal-unloading station and the outside stockpile, between the coal yard and the crusher station, between the crusher station and the tripper room, and n...
