Agitator Pumps Power through Coal Slurry at Electric Plant

Coal and coal dust are abrasive and corrosive. Spraying piles of coal with water—to suppress the coal fines to control explosion risk and improve air quality—creates a heavy acidic and abrasive slurry of coal fines, dust, and suspended coal fragments. The same happens when rain falls on and percolates through coal piles. Coal’s abrasive
