Steel Smelter Ash

Steel Smelter Ash

IN BRIEF

The new Caofedian Industrial Zone on the coast of the Bo Hai sea in N.E. China is seeing rapid growth as a center for steel production, chemical processing, oil refinement and import processing. The customer purchased nine systems comprising mostly Ashveyor and Denseveyor pneumatic conveying systems for the handling of flue gas ash captured through ESP and baghouse processes. The steel plant is a 500T/day steel processing plant with the need to transfer 87 tons of smelting ash per hour to large on-site storage facilities prior to truck and train load-out.
