rotary kiln vs fluidized bed

The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a shaft furnace, rotary kiln furnace or fluidised bed. Sponge iron can be produced in the form of Direct Reduced Iron (DRI), Hot Briquetted Iron (HBI) and Cold Briquetted Iron (CBI); also Low Reduced Iron (LRI), which is pre-reduced iron ore with a reduction and metallisation degree lower than that for …

    fluidized bed furnace- an overview | sciencedirect topics

    Combustion systems include the fluidized-bed furnace, fire-grate furnace, rotary kiln furnace, and vortex combustion furnace (JSME, 1996). Fire-grate furnaces can be divided into upflow and downflow systems. In an upflow system, the gas generated by thermal decomposition of biomass in a fire grate goes upwards to be burned

    process and technological aspects of municipal solid waste

    The paper proposes a critical assessment of municipal solid waste gasification today, starting from basic aspects of the process (process types and steps, operating and performance parameters) and arriving to a comparative analysis of the reactors (fixed bed, fluidized bed, entrained bed, vertical shaft, moving grate furnace, rotary kiln, plasma reactor) as well as of the possible plant

    (pdf) thermal treatment of hazardous wastes: a comparison

    The rotary kiln was fed in a batch mode in order to simulate the passage of solids through a kiln. The fluidized bed was fed in both batch and continuous modes. Samples were removed from the kiln (bottom ash) and transition section (fly ash)
