  • Heat exchanger for fluidized bed reactor
    Patent number: 3983927
    Abstract: A fluidized bed reactor is provided with vertically oriented heat exchange coils for controlling the temperature of the fluidized bed. Tuyere elements discharge fluidizing gas at a level substantially above the constriction plate. The bed solids below the level of the tuyere ports constitute a static layer during fluidization and the lower return bends of the heat exchange coils are embedded in this layer and so are shielded from erosion by the fluidized solids of the bed proper.
    Type: Grant

  • Heat transfer element and tuyere for fluidized bed reactor
    Patent number: 3982901
    Abstract: A fluidized bed reactor is provided with heat exchange coils for controllng the temperature of the fluidized bed. The heat exchange coils are vertically oriented and elements thereof pass through the constriction plate of the reactor. Multiple function Tuyere elements are provided which admit air into the reaction chamber from the windbox, provide for passage of elements of the heat exchange coils through the constriction plate, structurally support the heat exchange coils in position and constitute thermal sleeves for accommodating differential thermal expansion of the heat exchange coils and the constriction plate.
