      Fluidized Bed Boiler - an overview | ScienceDirect Topics

      The fluidized bed boiler is gaining in popularity and has overtaken the grate-fired boiler in biofuel power generation applications. The principle is very simple: air is blown through a bed of sand and fuel particles at a velocity that is sufficient to suspend the particles on the airstream but not able to lift them permanently out of the bed, that is, 1–3 m s −1 at 800–900 °C.
