  • Grate kiln systems liming

    The grate chain travels flat and straight. The grate travels through a furnace with several zones that expose the pellets to different temperatures. Once the pellets are discharged into the kiln, the grate chain returns underneath. The grate is driven by a motor with gearbox or hydraulic drive. The grate is supported by rollers. Rotary kiln

    4.3.1.1 Grate/Kiln Furnaces. For grate/kilns, data were available on emissions of a wide variety of pollutants from the production of both acid pellets and flux pellets. The following paragraphs first describe how the candidate emission factors for grate/kiln furnaces were developed. 4.3.1.1.1 Filterable PM.

  • Mercury Chemistry and Mössbauer Spectroscopy of Iron

    Samples were also collected from beneath the grates in active induration furnaces at four taconite processing facilities. An important distinction between taconite operations is that some use “grate-kiln” furnaces (Fig. 1) while others operate “straight-grates” (Fig. 2). Grate-Kiln facilities dry and heat pellets on a grate, but final
